Attention all traders, the CoW Swap herd is thrilled to announce TWAP-tember, the greatest trading extravaganza of the year!


Introducing TWAP-tember

On CoW Protocol, rather than sending on-chain transactions with predefined swap instructions, users submit signed  [intent-to-trade messages](/learn/cow-protocol-glossary#:~:text=Intent%20to%20Trade). These messages contain some order details, like which assets to trade in which amounts, but leave other details to be optimized by  [solvers](https://docs.cow.fi/cow-protocol/tutorials/solvers).

One important parameter of these intents is min_out — the minimum amount of buy tokens a user is willing to receive for their sell tokens (or the buy amount, minus the maximum allowable slippage set by the user). Min_out works really well when a trade is intended for immediate or near-immediate execution, because it allows solvers to improve prices for users while protecting them from unfavorable price movements. However, when prices fluctuate a lot, min_out can be overly-restricting.

## **What is delayed execution trading?**

Simply put, delayed execution trades are trades intended to execute at some point far in the near future.

Many smart contract wallet users, such as DAOs, frequently need to create these types of orders. Take the following examples:

-   DAOs that need trades to execute after passing a governance process
-   Groups that need hours to collect signatures to execute trades from a multisig wallet
-   Applications that process automated swaps years in the future (e.g. for payroll or treasury management)

With extra time, prices can fluctuate wildly — and this creates a dilemma for traders:

If the buy token price falls and the min_out is too high, the order might not execute. But if the min_out is too low, the trader risks getting an unnecessarily poor execution price. (CoW Protocol solvers compete against each other to give users better prices, but placing such a high level of trust in solvers can be undesirable for very high-volume traders.)

![1-what-is-milkman.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_what_is_milkman_0518ebe1f4.webp)

If a user signs an intent to swap 1 ETH for a “min out” of 2000 USDC, there is no way for the trade to return any less than 2000 USDC

![2-what-is-milkman.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_what_is_milkman_08ab1cbaac.webp)

But setting a low “min out” risks leaving money on the table

## **What is Milkman?**

Milkman is a smart contract that solves the above dilemma for smart contract wallets.

It does this by allowing smart contracts to specify an on-chain data source (such as an oracle) to use as a reference for min_out — effectively turning min_out into a dynamic price backstop for their trade.

Let’s say you want to sell 1000 ETH for USDC, but you want to do it far in the future. To protect yourself from volatile price movements, you can supply Milkman to create the order based on with the Chainlink price feed for ETH/USDC, and Milkman at the time of order placement will dynamically adjust the minimum amount you’ll receive based on that price feed.

When the time comes to execute your trade, CoW Protocol will receive it with a min_out that accurately reflects prices at that point in time; and solvers will compete to improve the price on top of that, as they always do.

![3-what-is-milkman.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/3_what_is_milkman_7f4ab32979.webp)

## **Milkman for DAOs**

Milkman is particularly well-suited to many DAO-related use cases, because DAO governance processes often delay trades and because amounts traded by DAOs can be very large.

Several well-known DAOs, including  [Aave](/learn/aave-trade-breakdown)  and  [ENS](/learn/ens-trade-breakdown), have already used Milkman to trade over $20M worth of tokens. Beyond allowing these DAOs to count on reliable prices, Milkman lets them reduce their overall number of governance votes and gives them standard CoW Swap benefits like best price execution and  [best-in-class](https://eigenphi.substack.com/p/sandwich-mevs-impact-on-cow-swap)  MEV protection — critical for large trades.

Milkman is also natively integrated as a  [recipe on Tally](/learn/tally-recipe-for-cow-swaps), the widely-used DAO management platform — removing even more trading friction for DAOs.

## **Technical details**

Milkman follows a UniV2-style interface. To interact with Milkman, smart contracts need only to call the following function:

> _function requestSwapExactTokensForTokens(_
> 
> _uint256 amountIn,_
> 
> _IERC20 fromToken,_
> 
> _IERC20 toToken,_
> 
> _address to,_
> 
> _address priceChecker,_
> 
> _bytes calldata priceCheckerData_
> 
> _)_

The priceChecker is the data feed provider, and priceCheckerData is an array of arbitrary bytes that the function passes to the price checker (e.g. the desired slippage tolerance).

Price checkers have been deployed for Chainlink, Curve, SushiSwap, Uniswap V2, Uniswap V3, and combinations of these. The core Milkman code can be found  [here](https://github.com/cowdao-grants/milkman). Anyone can run a  Milkman bot, which simply functions as a hook that watches for new swap requests and surfaces them to CoW Protocol. Running a bot is fairly easy if you have a Kubernetes cluster; the instructions are in the repo.

Milkman was developed by  [Yearn Finance](https://yearn.fi/)  in partnership with CoW Protocol, through the  [CoW Grants Program](https://grants.cow.fi/).

Long live Milkman! And may you benefit from his commitment to bringing you favorable prices!

What is Milkman? CoW Swap’s Solution for Delayed Execution Trading

Surplus notifications are now live on CoW Swap! Just navigate to your account page to see the total amount of price surplus CoW Swap has generated across all your trades.

Surplus notifications will also pop up after each trade, showing you how much extra you’ve earned for that trade!

![announcing-cow-swap-surplus-notifications-cover-photo.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/announcing_cow_swap_surplus_notifications_cover_photo_dbb7d409c9.webp)

## What is Surplus?

On CoW Swap, we call any improvement over your quoted price “surplus”.

-   **Positive Slippage**: Sometimes the market moves to your advantage and the asset you’re trading becomes cheaper between the time you’re quoted and the time of execution. On CoW Swap, that price savings is passed on to you
-   **Coincidence of Wants (CoWs)**: If your order is matched peer-to-peer with someone else, you save on gas costs and LP fees. That price surplus is also passed along to you
-   **Any other price improvement**: If the solvers can find a better source of liquidity than they originally quoted, or improve the price in any other way, this price improvement is forwarded to you.

## CoW Swap Passes Along the Most Surplus

CoW Swap is the only exchange that passes along all types of price improvements. Positive slippage, gas savings, and other optimizations usually end up in the protocol treasury for most DEXs and DEX aggregators. At CoW, we put our users first, so you can rest assured that if we find a better price, it’ll be you we tell first.

Announcing CoW Swap Surplus Notifications

Slippage is the difference between the price at which a cryptocurrency order is submitted and the price at which it’s executed.

Since crypto prices fluctuate constantly, it’s necessary to set a “slippage tolerance” for every trade which allows users to accept a slightly higher or slightly lower price for their trades at execution time.

## What is Slippage?

Slippage is the amount that a trade price may vary by between the time the trade is placed and the time it actually executes.

To better understand slippage, let’s take a look at an example.

Let’s say a user places an order to buy 1 ETH while the price of ETH is exactly $3,000. By the time the order executes, however, ETH has shifted slightly in price and the user ends up only paying $2,980 for 1 ETH. The $20 difference between the $3,000 that they initially placed their order at and the $2,980 per ETH price that the order eventually executed for is known as slippage.

## What is a Slippage Tolerance?

![1-what-is-slippage.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_what_is_slippage_0b1a557216.webp)

_The slippage setting on_ [_CoW Swap_](https://swap.cow.fi/#/swap?utm_source=medium&utm_campaign=slippage-article)

Decentralized exchanges require users to set a “slippage tolerance” percentage every time they make a trade. This determines how much deviation the trader is willing to accept in the price of the asset they are trading.

For example, if a user wants to buy 1 ETH, it might cost them $3,000 at the time they place their trade, but by execution time that price may have changed to $2,950 (approximately 2% less). If they had no slippage tolerance, their trade would fail, potentially still incurring gas fees and forcing them to resubmit the transaction.

Meanwhile, if they set a slippage tolerance of 2% when they place their trade, their trade would be able to execute at prices 2% below or 2% above the quoted price. In this example, this would allow the trade to go through as long as 1 ETH is between $2,940 and $3,060 at execution time.

All decentralized exchanges use slippage tolerances for user trades, so it’s important to understand the concept and know what percentage to use.

## What Slippage Tolerance Should I Use?

As a rule, you should try to use the smallest slippage you can get away with. On most exchanges, the default slippage tolerance is between 0.5% and 2%, however, the optimal slippage tolerance depends on the type of asset you’re trading.

Generally speaking, the more volatile a crypto asset is, the higher a slippage tolerance you’ll need to use.

**For stable assets**: Assets like stablecoins generally require a low slippage tolerance because their prices don’t fluctuate by much. Exchanges specializing in stablecoins (such as Curve) set the default slippage tolerance for these assets at between 0.25% and 0.5%.

**For standard assets**: The standard slippage tolerance for most trades is between 0.5% and 2%. This is a good range to stick to when trading established assets with medium volatility profiles such as Ethereum.

**For volatile assets**: When it comes to cryptocurrencies whose prices jump wildly — such as memecoins or new token launches — users will often need to use a higher slippage tolerance than 2%. There is no hard and fast rule here. Depending on the volatility of the asset, user trades may require a double-digit slippage, maybe even in the high double-digits, in order for the trade to go through.

It’s important to understand, however, that setting a high slippage tolerance leaves you vulnerable to price exploitation in the form of maximal extractable value (MEV).

## The Dangers of High Slippage

While setting a high slippage tolerance helps ensure that your transaction goes through, using too high of a slippage tolerance can be dangerous.

Blockchains like Ethereum process transactions sequentially, meaning that transactions in a block execute one after the other. This, combined with the mechanism of  [automated market makers (AMMs)](/learn/cow-protocol-glossary#:~:text=amm), means that value-extracting bots can strategically place transactions before and after your trade to exploit your slippage tolerance and extract value from you. This type of price exploitation is known as maximal extractable value (MEV).

### Sandwich Attacks

![2-what-is-slippage.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_what_is_slippage_e0af2a8fb5.webp)

_The flow of a sandwich attack_

A  [sandwich attack](/learn/what-is-a-sandwich-attack-and-how-can-you-protect-yourself)  is a form of MEV that can occur whenever a user places a trade with a high slippage tolerance. Specifically, this is a slippage tolerance that is larger than what the market price may call for.

When a user places this trade, an MEV bot (known as a “searcher”) places another transaction before the user transaction, pushing the price of the traded asset up to the original user’s maximum slippage tolerance. The original user’s transaction then goes through, pushing the price up even further. Finally, the searcher sells the asset, cashing out on the price difference.

In the end, the user loses out because their transaction could have gone through at a lower slippage. Instead, the searcher forced the user’s transaction to execute at the limit of its slippage tolerance and kept the difference for themselves.

This isn’t a rare occurrence either, MEV is a systemic problem for chains like Ethereum where MEV losses total over $1.3 billion to date.

## What is Auto-Slippage?

Unfortunately, there is no perfect way to predict what the ideal slippage should be for every trade. In crypto, users are often competing against more sophisticated trading parties and bots who can take advantage of their sub-optimal traders for their own profit.

To protect users from MEV, some exchanges offer auto-slippage functions which automatically calculate the slippage tolerance that trades should use based on the assets they are trading and market conditions.

## CoW Swap: Premium Auto-Slippage and Delegated Trade Execution

![3-what-is-slippage.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/3_what_is_slippage_4170bdeb89.webp)

One of the exchanges with the most advanced auto-slippage features is CoW Swap. CoW Swap is an intents-based DEX aggregator that uses third parties known as “solvers” to execute trades on behalf of users. Solvers calculate the optimal slippage tolerance for user trades and take on all the risks of MEV.

![4-what-is-slippage.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/4_what_is_slippage_4f3c2ce1e4.webp)

In fact,  [data shows](https://blog.cow.fi/do-cows-slip-age-less-389150154f84)  that CoW Swap offers a low default slippage the overwhelming majority of the time compared to 0x and 1inch.

On CoW Swap, you can make the perfect trade every time, even if you’ve never heard of “slippage” before!

Welcome back to another CoW Update, where we break down the most notable developments of the last few weeks at CoW Protocol.


CoW Protocol July 2023 Highlights

_CoW Swap, a DEX trading platform, has undergone a remarkable transformation over the last few years._

_The platform has transformed substantially from its early days as a dutch auction swap to a leading authority on intents forging new ground through conditional programmatic orders. In a recent presentation, Alex Vinas, the Product Marketing Manager at CoW Swap, traced CoW Swap’s journey and offered insights into its history, pivotal developments, and the promise of the brand new_ [_Programmatic Order Framework_](/learn/introducing-the-programmatic-order-framework-from-cow-protocol) _(Please Note: At the time of the presentation, the Programmatic Order Framework was known as “Composable CoW.”)_

_What follows is a transcript of Alex’s talk:_

## A Brief History of CoW Swap

![1-navigating-the-evolution-of-cow-swap.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_navigating_the_evolution_of_cow_swap_ebc6a318b6.webp)

Cow Swap’s journey began back when its current team was a part of Gnosis. At the time, the team was working on decentralized mechanisms for trading prediction market outcomes. It was this work that helped bring to life the famous “x*y=k” formula for AMMs back in 2017 — earlier than even the founding of Uniswap.

### Dutch Auctions

While their initial ideas were good, Gnosis recognized the vulnerabilities of the traditional AMM design and its weakness toward MEV, so the team pivoted to Dutch auctions.

However, this mechanism also came with its own set of downfalls.

It worked well for initial coin offerings and wasn’t susceptible to MEV, however it fell short when faced with the growing diversity of tokens on Ethereum. Dutch auctions also had to compromise on speed, resulting in a slow trading experience for users.

### Batch Auctions

The team realized they needed a new auction mechanism for trading large amounts. It was here that the batch auction was born.

After cycling through several different iterations of batch auction DEX’s, CoW Protocol was born in 2021. CoW Protocol was built on the learnings from earlier projects and introduced innovative features like an intents-based architecture and comprehensive MEV protection.

The product was designed to address the challenges faced by retail users, smart contract accounts, and decentralized autonomous organizations (DAOs). At the core of the protocol is a delegated trading execution model in which bonded third parties known as “solvers” handle order execution on behalf of users.

The delegated trading model of CoW Protocol offers several benefits:

-   **For retail users**, it abstracts away Ethereum complexities such as gas fees, MEV, and the need to search for the most up-to-date AMM pools
-   **For smart contract wallets,** it enables a seamless trading experience. Before CoW Swap, smart contract wallets often had their trade execution paths expire by the time they gathered signatures. Today, smart contract wallets only commit to a particular  _price_  (rather than a specific trading path), leading to more flexibility and optimizing order execution
-   **For DAOs**, features like the  [Milkman](/learn/what-is-milkman-cow-swaps-solution-for-delayed-execution-trading)  contract bridge the gap in time between a governance proposal and an on-chain swap by allowing the DAO to specify an on-chain price feed from which to pull real-time prices (rather than specifying a fixed price)

### The Path Toward Smart Contract Intents

Initially, gasless trading was limited to EOAs since smart contract wallets don’t have private keys and thus can’t sign messages. It wasn’t until the introduction of  [ERC-1271](https://eips.ethereum.org/EIPS/eip-1271)  smart orders that gasless trading was enabled for smart contracts using a new method called “isValidSignature.” This allowed smart contracts to delegate order placement while maintaining control through interactive signature verifications.

The first implementation of smart orders in CoW Swap was the  [native ETH flow](https://medium.com/@cow-protocol/moooove-over-weth-native-eth-trading-is-now-live-on-cow-protocol-96f107e53a49)  which allowed traders to trade ETH just like they would any other ERC-20 token. The second implementation was the  [Milkman](/learn/what-is-milkman-cow-swaps-solution-for-delayed-execution-trading)  contract. Milkman protects governance-based swaps from price exploitation as users specify an on-chain data source from which to pull prices rather than specifying a fixed amount and slippage. This allows the “minOut” variable of a swap to be modular and enables much more streamlined governance-based swaps.

While ERC-1271 smart orders have advantages including conditional on-chain guarantees, they also have drawbacks: they are gas-heavy for autonomous execution, require trust in an intermediary contract holding funds, and are limited to one order per signature.

## Enter the Era of Programmatic Orders

Programmatic orders build on top of batch auctions to enable even more user-friendly, trustless, and autonomous trading.

Programmatic orders take advantage of ERC-1271 smart orders to unlock intents for smart contracts. This has been transformative for the ecosystem, as it allows smart contracts to delegate order placement while still ensuring secure and customizable trading conditions.

[The Programmatic Order Framework from CoW Protocol](/learn/introducing-the-programmatic-order-framework-from-cow-protocol)  allows users to execute unlimited smart orders in parallel, with enhanced gas efficiency and full self-custody. The Framework opens the door to a number of use-cases including automated fee collection, DAO payrolls, TWAP orders, and even private conditional orders such as stop-loss.

### Understanding the Programmatic Order Framework Architecture

Programmatic orders operate through a decentralized architecture that ensures trustless execution by holding assets in the user’s safe.

![2-navigating-the-evolution-of-cow-swap.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_navigating_the_evolution_of_cow_swap_93d6afc424.webp)

The Programmatic Order Framework involves four main customizable parameters which combine with the order handling of CoW Protocol to allow developers to deploy ANY codeable strategy.

Each conditional order has the following properties or data available at settlement:

-   _handler_  — verifies the conditional order parameters via a smart contract (Programmatic Order Framework)
-   _salt_  — allows for multiple conditional orders of the same type and data (Merkle root)
-   _staticData_  — data available to ALL discrete orders created by the conditional order
-   _offchainData_  — data optionally provided from off-chain to a discrete order

## The Future of Programmatic Orders

Programmatic Orders open a world of possibilities by allowing users to turn their Safes into autonomous traders. While the Programmatic Order Framework is currently developer-focused, it unlocks a wide range of use-cases for retail users as well. The integration of  [CoW Hooks](/learn/cow-hooks-you-are-in-control)  in the future could further enhance the user experience, combining composable smart orders with additional functionalities.

In conclusion, CoW Swap’s journey to perfect DeFi orders embodies the protocol’s commitment to users and innovation. The Programmatic Order Framework emerges as a pivotal milestone, showcasing CoW Swap’s adaptability and dedication to meeting the evolving needs of the crypto community.

Navigating the Evolution of CoW Swap: From Market Orders to Programmatic Orders

Since its inception, DeFi has relied on  [automated market makers (AMMs)](/learn/cow-protocol-glossary#:~:text=amm)  directly to facilitate the majority of trading volume. More recently, however, auctions have emerged as an innovative trading mechanism that addresses some of the major shortcomings of AMMs.

Below, we examine these shortcomings and compare and contrast two popular auction solutions— Dutch auctions and batch auctions.

## The Shortcomings of AMMs

CF-AMMs, first proposed by Gnosis in 2017 and later popularized by protocols like Uniswap, are a natural fit for a world of frequent token launches and volatile assets. The core function of a CF-AMM is the rebalancing of token prices as orders come in. These AMMs rely on permissionless liquidity pools to facilitate trades for any ERC-20 token pair.

Due to their design, however, CF-AMMs leave traders exposed to price exploitation in the form of  [maximal extractable value (MEV)](/learn/understanding-mev-protection). Since orders on AMMs get executed sequentially, malicious parties can re-order trades in the Ethereum mempool and take advantage of users. MEV has become a lucrative industry for the most resourceful traders out there, but those profits come directly out of the pockets of everyday users.

The propensity of AMMs to be exploited indicates that continuous-time venues may not be the ideal solution for trading on decentralized exchanges.

## The Benefits of Auctions

![1-batch-auctions-vs-dutch-auctions.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_batch_auctions_vs_dutch_auctions_20effdf8c3.webp)

At its core, Ethereum is an auction — each block is limited in space, so validators auction off “blockspace” to the highest bidders. It turns out that a similar mechanism works well when it comes to trading. Auctions have presented a viable alternative to continuous-time trades in a new field known as “[Order Flow Auctions](/learn/understanding-order-flow-auctions).”

There are several points to consider when examining how auctions make sense in the context of blockchains:

1.  Blockchains aren’t continuous, so trading on a continuous system doesn’t make sense. It only leads to a “first come, first serve” mode of operation that ultimately becomes a race to the bottom.
2.  Auctions work to benefit traders as there can be multiple bidders for any given order, providing better prices by aggregating fragmented liquidity.
3.  Grouping multiple orders together in an auction presents opportunities for matching liquidity peer-to-peer rather than having to tap on-chain AMMs.

Auction mechanisms are not monolithic however. There are multiple types of auctions to take into account when considering what may make the most sense for Ethereum traders.

## Dutch Auctions

![2-batch-auctions-vs-dutch-auctions.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_batch_auctions_vs_dutch_auctions_fbaf900f7b.webp)

_([Source](https://medium.com/coinlist/a-primer-on-dutch-auctions-525036d24d10))_

One of the most common auction mechanisms is the Dutch auction. Dutch auctions work by offering an asset at a high starting price and then lowering the price over time until a willing bidder is found. This method identifies buyers quickly, making for a fast settlement.

Trading solutions like  [UniswapX](https://blog.uniswap.org/uniswapx-protocol)  employ Dutch auctions to settle trades with the speed of a traditional AMM, but with some added benefits.

### Pros

**Solver Competition**: Multiple parties, or “solvers,” can bid on a given asset, finding the most competitive price for the user’s assets.

**MEV Protection**: Dutch auctions protect users from MEV by relying on a third party for execution, meaning the user is never exposed to an AMM where their trade could be front-run or sandwiched.

### Cons

**Centralized**: Market makers have to have the assets in their inventory, leading users to essentially be at the mercy of the liquidity that the bidding parties have on hand.

Dutch auctions provide important benefits over continuous order trading. However, they only support auctioning one token at a time and they suffer from liquidity fragmentation as liquidity for a single token is spread across various venues.

It was this problem that inspired the creation of Gnosis Protocol V1 — the precursor to CoW Swap. This protocol relied on a different auction mechanism: the batch auction.

## Batch Auctions

![3-batch-auctions-vs-dutch-auctions.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/3_batch_auctions_vs_dutch_auctions_7431306f4d.webp)

_An illustration of the batch auction mechanism on CoW Swap_

A batch auction groups together a set of orders intents and executes the entire batch as a single transaction.

This allows multiple users to trade multiple assets within a single auction (unlike Dutch auctions). Having multiple orders in a single batch even enables  [peer-to-peer swaps](/learn/what-are-cows-on-cow-swap)  which provide better prices than any on-chain venue.

Finally, while Dutch auctions rely on a price-decay bidding process, batch auctions encourage solvers to find the best execution route for each trade, incentivizing better execution rather than just the quickest settlement.

### Pros

**Solver Competition & MEV Protection**: Just like Dutch auctions, batch auctions rely on a delegated execution model where solvers compete to find the best prices for users and protect orders from MEV.

**Surplus Capturing Orders**: Batch auctions provide an extra layer of efficiency over Dutch auctions by grouping multiple orders together. This allows liquidity to be shared between orders peer-to-peer, providing better prices than any on-chain venue. When orders  _do_  have to go on-chain, batching provides gas efficiency, further contributing to savings.

**Multiple Trades Per Auction**: Batch auctions aren’t limited to just a single asset per auction. This means that a single settlement may include multiple traders, each trading a different asset.

### Cons

**Speed**: While other modes of trading settle orders instantaneously, batches have to be open for some period of time to collect orders before executing them on-chain. Speed issues can be mitigated by executing one batch per Ethereum block, making batch auctions run at the speed of Ethereum block settlement.

Batch auctions make sense as a natural fit for Ethereum, mirroring the Order Flow Auction mechanism of the block but at the dApp level. Today,  [CoW Swap](https://swap.cow.fi/#/swap?utm_source=medium&utm_campaign=dutch-vs-batch)  is the largest production-scale implementation of batch auctions for DeFi trades.

## The CoW Approach to Batch Auctions

![4-batch-auctions-vs-dutch-auctions.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/4_batch_auctions_vs_dutch_auctions_eb922dc3cf.webp)

[CoW Swap](https://swap.cow.fi/#/swap?utm_source=medium&utm_campaign=dutch-vs-batch)  utilizes batch auctions to ensure traders get optimal prices while being protected from MEV.

The process starts with traders sending signed “intent to trade” messages to an order book, which CoW Swap then groups into batches. Solvers then search both on-chain and off-chain liquidity pools for the best prices. An auction is conducted for each batch to select the solver that provides the highest price surplus (the difference between the quoted and actual execution prices) for the orders. Finally, the winning solver executes these orders on-chain, ensuring users benefit from a uniform clearing price for all assets.

The future of batch auctions lies in targeting smaller batches where one batch is equal to one Ethereum block. This mitigates all speed issues related to batch auctions, making them execute as quickly as any other type of DeFi trade.

Auctions are all the rage these days… but which auction method is really the best?


Batch Auctions vs. Dutch Auctions in Crypto

**Intent to Trade:** When users submit orders on CoW Swap, they are not actually initiating a blockchain transaction, like they would on Uniswap. Instead, orders are submitted as signed “intent to trade” messages which include the details of the intended trade, but are not actually submitted to the blockchain. From here, independent parties known as “[solvers](https://docs.cow.fi/cow-protocol/tutorials/solvers)” find the best execution path for the specified trade and execute the trade on-chain on behalf of the user. If a trade route cannot be found for any reason, the transaction will not execute and the user will not be charged a fee for the failed transaction.

**Delegated trade execution**: When it’s time to actually execute a settlement (which can contain multiple trades),  [solvers](https://docs.cow.fi/solvers/solvers)  lock in the execution path and submit the transaction to the blockchain. Note here that it is the solvers who are completing the transaction on behalf of the user, meaning that they determine the correct slippage tolerance to use, the right amount of gas fees, as well as taking on the risk of negative price movements or MEV.

The delegated trading model also means that traders using CoW Swap do not have to spend ETH to cover gas. Instead, gas fees come out of the sell token when making trades.

**AMM**: Automated Market Makers, also known as “DEXs,” are trading mechanisms that allow traders to buy and sell assets in real-time. Unlike traditional “orderbook” trading, which relies on counterparties for every transaction (you need a seller in order to buy and a buyer in order to sell), AMMs work by maintaining a constant ratio between the prices of two assets. For example, ETH and COW. AMMs use the formula “x*y = k” to determine a fair price based on the ratio between two assets (x and y) in the liquidity pool.

Any time a trade alters this ratio by depleting the supply of one asset and increasing the other, the prices of the assets adjust in order to preserve the established ratio. For instance, if a trader buys COW and sells ETH, the COW price rises and the ETH price falls. The opposite happens when traders sell COW and buy ETH.

**Slippage Tolerance**: When placing a trade, traders set a “slippage tolerance” for their transactions which represents the maximum price difference they’re willing to accept for their trade. For example, if ETH is trading at $2,000 and you place an order to buy ETH with a 5% slippage tolerance, you’re willing to buy ETH at up to $2,100. If ETH goes above $2,100, however, your trade will fail as it’s outside your slippage tolerance.

Some amount of slippage tolerance is always necessary because the prices of crypto assets are constantly fluctuating. By the time your trade executes, the price may have moved. Setting your slippage tolerance too high, however, leaves room for searchers to sandwich your trades.

**Price Impact**: Crypto markets, like all markets, are based on supply and demand. AMMs maintain “liquidity pools” of assets which they use to fill trades. Each trade drains some amount of this liquidity and moves the asset's price. This price movement is known as “price impact.”

The larger the trade, the bigger the price impact. A trade of $100 ETH will not move the price of ETH very noticeably, since it only makes up a tiny fraction of the available liquidity. A trade of $1,000,000 ETH, however, will noticeably move the price of ETH.

**Transaction Reordering**: Blockchain transactions do not always enter the block in the order that they were submitted. Searchers can “bribe” the validators responsible for creating the block to get them to arrange transactions in a specific sequence. This transaction reordering is what makes all of MEV possible.

**EOA Wallets:**  Externally owned accounts (EOAs) are Ethereum accounts controlled by private keys. EOA wallets — for example: MetaMask, Rainbow, and Rabby Wallet — allow users to (1) send, hold, and receive Ethereum-native tokens, and (2) interact with smart contracts. Unlike smart contract wallets, EOA wallets are usually generated with a seed phrase and do not have any code associated with them.

**Milkman**: The  [Milkman](https://github.com/charlesndalton/milkman)  smart contract ensures trades are executed for the real-time price or better by utilizing a price checker, such as a Uniswap pool or an oracle. Instead of setting a fixed slippage tolerance based on the current market price, DAOs can utilize Milkman to determine a maximum percentage deviation from a real-time price sourced from a price checker, guaranteeing that their trade will finalize at a fair market price. If a trade can’t be executed within the defined price or better, the order remains pending until the price condition is met, or until the trader cancels the order.

A list of terms & definitions related to CoW Protocol


CoW Protocol Glossary

An MEV blocker is a piece of blockchain infrastructure that protects orders from price exploitation resulting from MEV (Maximal extractable value).

Under the hood, it’s  [RPC endpoints](https://www.quicknode.com/docs/ethereum)  that function as MEV Blockers by routing transactions through specialized mempools which protect them from MEV and even send rebates back to traders when their trades leave money on the table.

There’s a lot of moving parts when it comes to MEV blockers, so let’s break the topic down one step at a time.

## What is MEV?

An MEV blocker is a piece of software that protects user transactions from suffering MEV exploitation… but what is MEV?

MEV (Maximal extractable value) is a hidden tax on all types of Ethereum transactions. Any time you make a large trade, mint a valuable NFT, or even provide liquidity to a liquidity pool, you are at risk of experiencing price exploitation through MEV. To date, MEV has caused over $1 billion in trading losses and continues to increase by the millions each day.

![1-what-does-an-mev-blocker-do.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_what_does_an_mev_blocker_do_80b9b36ca6.webp)

MEV is carried out by traders known as “searchers” who monitor pending Ethereum transactions and  bribe block builders  to order the transactions in a specific order, extracting profit in the process.

Find out more about the specifics of how MEV attacks work in our  [“Understanding MEV” series](/learn/understanding-mev-protection).

## How do MEV Blockers Work?

Since MEV relies on  [reordering transactions](/learn/understanding-mev-protection)  from the order in which they were submitted to a new, more profitable order, it’s possible to cut the process short by sending transactions to a specialized network of searchers bound by unique rules that ensure favorable execution for users.

These searchers cannot frontrun or sandwich transactions. Rather, they capture value by  [backrunning](/learn/what-is-backrunning-mev-attacks-explained)  large orders and sending a large portion of the backrunning profits back to the users as a rebate. So, as a user, you’re not only protecting yourself from harmful price exploitation in the form of frontrunning and sandwich attacks, you also have someone looking out for you any time you leave money on the table.

## What is an RPC endpoint?

We mentioned earlier that under the hood, MEV blockers run through RPC endpoints. An RPC endpoint is a communication layer between the blockchain and a user’s wallet. RPC endpoints relay messages from the wallet that  [RPC nodes](https://www.alchemy.com/overviews/rpc-node)  use to add orders to the blockchain.

RPC endpoints are the perfect place for MEV protection because they are an intermediary layer between the wallet and the blockchain, safely re-routing transactions towards the specialized network of searchers we mentioned earlier, rather than letting them end up in the public  [mempool](https://www.blocknative.com/blog/mempool-intro)  where malicious searchers lie in wait.

## Order Flow Auctions for MEV Blockers

![2-what-does-an-mev-blocker-do.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_what_does_an_mev_blocker_do_7de134111f.webp)

MEV Blocker RPCs rely on an emerging blockchain mechanism known as  [order flow auctions](/learn/understanding-order-flow-auctions). Order flow auctions are bidding mechanisms used at various levels of the Ethereum stack which pit multiple execution parties against each other to find the one that can provide users with the best value for their transaction.

Currently, block building incentivizes MEV extraction by awarding the privileges of creating the next block to the builder who can extract the most value from the trades. Order flow auctions invert this dynamic — incentivizing auction participants (in the case of MEV blockers, this is the specialized network of searchers) to instead find as large of a rebate as possible for the user submitting the transaction. The searcher who bids the most to backrun a trade wins the auction, capturing some small value of the proceeds for themselves and sending the rest back to the user as a rebate.

## Should you use an MEV Blocker?

While many people have yet to learn about MEV blockers, they’re quickly being adopted by some of the most savvy traders to protect their trades, NFT swaps, LP positions, and more. MEV is an increasingly significant problem for traders of all sizes and MEV blockers are designed to outsmart the searchers with the latest innovations in market mechanics.

You may have heard that MEV is only a problem for large trades, but as searchers get more and more sophisticated, this is becoming less true. Searchers can also extract value from small trades, especially in volatile markets, and beginner traders are especially susceptible to price exploitation as they may not yet know how to protect themselves.

MEV blockers provide robust protection without many downsides. As a user, you install the MEV blocker through your wallet and forget about it, meanwhile it’s quietly protecting you from price exploitation and even forwarding rebates from any money your trades leave on the table.

## MEVBlocker.io — CoW DAO’s Approach to MEV Blocking

![3-what-does-an-mev-blocker-do.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/3_what_does_an_mev_blocker_do_cc9833e466.webp)

[CoW DAO](https://cow.fi/)  became a first mover in the MEV blocker space when it introduced  [MEV Blocker](https://mevblocker.io/)  (yes, we coined the term) in April of 2023.

MEV Blocker (capital “B”) is an RPC endpoint developed by CoW DAO in collaboration with  [Beaver Build](https://beaverbuild.org/)  and  [Agnostic Relay](https://agnostic-relay.net/)  that’s built to protect Ethereum transactions from frontrunning and sandwich attacks. MEV Blocker sends transactions to a mempool of searchers who bid for the opportunity to backrun the trades, sharing any profits 90/10 with users (90% to users, 10% to searchers.)

To join  [over 600,000 Ethereum users receiving more than 1,000 ETH](https://dune.com/cowprotocol/mev-blocker)  in rebates, add MEV Blocker to your wallet by following the instructions  [here](https://mevblocker.io/).

# How to create a LVR Protected Liquidity Pool on CoW AMM

## Accessing the creation page UI

CoW AMM is a new type of AMM built from the group up to protect LPs from price exploitation in the form of [LVR](https://cow.fi/learn/what-is-loss-versus-rebalancing-lvr). Liquidity providers expect their tokens to earn yield, but most liquidity pools are actually not profitable after accounting for stale prices. Arbitrageurs exploit these stale prices at the expense of LPs. CoW AMM fixes LVR once and for all, with liquidity pools proven to outperform reference Balancer and Uniswap pools.

Now, you can create your own CoW AMM pools too! To get started, navigate to the [Balancer CoW AMM pool creator](https://pool-creator.balancer.fi/cow).

You can access the pool creator in several ways. The first is to navigate to the [CoW AMM liquidity pools page](https://balancer.fi/pools/cow), scroll down to the bottom, and click “create a pool.”

![Cowamm_poolguide_5.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/Cowamm_poolguide_5_fb12211f1f.png)

## Configuring your own LVR Protected pool for deployment

To get started, select the tokens you want to use to create your LVR-protected pool.

![Cowamm_poolguide_6.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/Cowamm_poolguide_6_542472caad.png)

After selecting your tokens, specify the deposit amounts. Keep in mind that the pool creator currently only supports 50/50 pools so add an equivalent dollar amount of both assets.

![Cowamm_poolguide_7.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/Cowamm_poolguide_7_124b34dcdb.png)

After selecting your assets and amounts, tick the checkbox confirming that you understand assets must be added proportionally or you risk loss of funds via arbitrage. Once you’ve done this, click the “Preview” button.

## Deploying your LVR Protected pool onchain

Creating a pool requires several approval and swap steps through your wallet. The first is the actual pool creation, to initiate this click the “Create Pool” button and check your connected wallet interface.

![Cowamm_poolguide_9.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/Cowamm_poolguide_9_7a477d22d7.png)

In your wallet, approve the pool creation by signing. Remember to double check that you are signing the correct transaction!

![Cowamm_poolguide_9.1.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/Cowamm_poolguide_9_1_bed5d89c73.png)

Once you’ve created the pool, click “Approve” to approve the first token you want to create a pool for.

Welcome back to another CoW Update, where we break down the most notable developments of the last few weeks at CoW Protocol.

CoW Protocol September 2023 Highlights

Don’t worry, trade happy! CoW Swap has been busy cooking up Conditional Orders, an architecture that allows developers (and their users) to create sophisticated orders of all kinds. At the core of this system is a flexible smart contract wallet that allows the protocol to implement its unique logic. What’s better than standing on the shoulders of giants in the ecosystem and within the Gnosis family  [Safe](https://safe.global/)?

Wait? Smart contract wallet?

That’s right: CoW Swap pioneered intents across the Ethereum space for EOAs (think MetaMask, Trezor, Trust Wallet, etc.), but what’s less well-known is that the protocol can actually work in a similar way for smart contracts by relying on a flexible intents system with the ERC-1271 integration. It sounds technical, but this standard is basically designed to allow smart contracts to “Sign” a message like any other EOAs. This is a familiar procedure for the seasoned CoWmunity, but Conditional Orders now allow anyone to define a set of conditions and have the smart contract wallet do the clicking for you.

Incubated through the  [CoW Grants Program](https://grants.cow.fi/), and supported by the Safe team throughout the testing/auditing process, the ExtensibleFallbackHandler is now live. Sounds complicated, we know! Put simply, this is a way to add extra powers to your Safe, while preserving the strong security guarantees that the Safe is well known for.

Upgrading your Safe’s fallback handler is a secure process, all you have to do is tick a box when placing an order, and your Safe upgrade will be batched with your order, making for a single-transaction order placement and upgrade. The contracts that implement this system have been audited both by an independent auditor, and an external auditor from Ackee Blockchain (You can read the final audit reports  [here](https://github.com/cowprotocol/composable-cow/tree/ab3addad9bc05acdbf5fb040eb5c336209b58e31/audits)).

The owl-eyed among you would be aware that smart contracts have always been able to use CoW Protocol, though this required both a transaction on chain to signal your intent, and that the orders be fixed (not conditional). Wave goodbye to these limitations!

With an ExtensibleFallbackHandler+ComposableCoW-enabled Safe you now benefit from all the CoW Swap features directly from your smart contract wallet: MEV protection, no failed swap transactions, at-execution path discovery, conditional orders, and batching if you need to do pesky things like approve or wrap ETH.

If you’re technically inclined, check out how you can  [start building with conditional orders using ComposableCoW](https://hackmd.io/@mfw78/HyuvoGt9h#), or drop into  [#tech-talk on our discord](https://discord.gg/cowprotocol)! While you’re busy reading up on how to write the latest and greatest conditional order, you could also be gradually buying up more of your favorite token using TWAP!

## What is a Safe fallback handler?

Long story short, Safe is designed to have strong security guarantees over basic operations (think executing transactions, spending your precious tokens, etc.), but there’s not enough time to program all functionality that a user may require. Therefore, the Safe can “forward” all function requests that it doesn’t recognize to another contract (the fallback handler).

**CRITICALLY**: Fallback handlers do  **NOT**  have the same authority as the Safe from which they were called. Due to the security architecture of Safe, it is not possible for the fallback handler to execute transactions on behalf of the Safe.

OK, the fallback handler can’t execute a transaction for you, so why should you care? Safe doesn’t by default (without a fallback handler) support ERC-1271 signatures. The standard deployment of a Safe deploys with CompatibilityFallbackHandler as the fallback handler, which has limited ERC-1271 support (meaning: it cannot read and thus, cannot be automated). CoW Swap intents super-charge this by allowing a Safe to also specify a smart contract that can sign messages for a particular application on its behalf.

This is where ComposableCoW takes over! 🐮🎶 You can think of ComposableCoW as an autonomous agent, signing orders that meet whatever conditions you have specified. After you create your first conditional order, the second transaction you see in the batch will enable ComposableCoW, which tells your Safe “I want ComposableCoW to be able to sign orders from CoW Protocol”. TWAP is just a conditional order type that works with ComposableCoW.

**CRITICALLY**: Due to the design of ERC-1271, all signature verification is  **read-only**  which means it is  **impossible**  for a ComposableCoW or any conditional order to directly access user funds (the movement of funds during a swap is initiated by the settlement contract  **ONLY**).

In summary, to make CoW Swap’s new TWAP order feature work:

-   Safe users need to upgrade their fallback handler(enables conditional signing)
-   Conditional orders are automatically placed in the CoW Protocol order book (now signed with the new handler)
-   Automated signing of orders means you may hear less of CoW’s trademark moo. Feel free to set  [this](https://github.com/cowprotocol/cowswap/blob/develop/apps/cowswap-frontend/public/audio/success.mp3)  as your phone’s notification tone if suffering withdrawal symptoms 🐄

CoW Swap takes security very seriously. The underlying Safe fallback handler code has been fully audited by both the Safe and CoW teams as well as by two independent external auditors, G0 and Ackee Blockchain. You can find all the audit final reports  [here](https://github.com/cowprotocol/composable-cow/tree/ab3addad9bc05acdbf5fb040eb5c336209b58e31/audits).

The solution presented follows Safe’s high security standards. What’s more, the fallback handler isn’t just about placing orders. It allows limitless and, as of yet, unknown functionality. Maybe you want to:

-   Define a custom method handler for any non-standard method (if you really want you can turn your Safe into an ERC-20 token)
-   Define a custom EIP-712 domain verifier, whereby a contract implementing ISafeSignatureVerifier can do your menial signing automatically (it is this interface that ComposableCoW implements to power the shiny new TWAP orders)
-   Define a set of methods (interfaceId) that your Safe supports, and report such using ERC-165

The architecture for the ExtensibleFallbackHandler can be viewed  [here](https://hackmd.io/@mfw78/HyuvoGt9h).

**NOTE**: Audits are not a guarantee that code is free from error. Use with caution.

We wish you much surplus and happy  [TWAP order trading](https://swap.cow.fi/swap?utm_source=medium&utm_campaign=fallback-handler)!

All you need to know about CoW Swap’s new Safe fallback handler


The vast world of DeFi offers many kinds of tokens, with more being added every day. Decentralized aggregators like CoW Swap allow users to swap between practically any two ERC-20 tokens, but sometimes you need to manually add a custom token before you can trade it.

## Add Custom Tokens

In order to display user balances, CoW Swap queries the blockchain to see what tokens a wallet holds. To ensure a smooth user experience, this analysis is limited to tokens included on official token lists such as CoinGecko.

![1-add-custom-tokens.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_add_custom_tokens_a00d95fa40.webp)

For this reason, your wallet may hold tokens that don’t show up in your balance on CoW Swap. This doesn’t mean you can’t trade them! The CoW Protocol network of  [solvers](https://docs.cow.fi/cow-protocol/concepts/introduction/solvers)  searches all available liquidity to bring you the best prices, even for tokens outside of the default lists.

To trade custom tokens, you simply need to add them to the UI. Here’s how:

## Step 1

Navigate to CoW Swap and click “Select a token.”

![2-add-custom-tokens.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_add_custom_tokens_c80ddc6351.webp)

## Step 2

A token list will come up. Here you can either search the name of your token or enter the contract address in the search box.

![3-add-custom-tokens.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/3_add_custom_tokens_f8dd21ae8e.webp)

## Step 3

For maximum security, you should always paste the official token contract address into the search box. This prevents any form of manipulation or phishing.

![4-add-custom-tokens.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/4_add_custom_tokens_1ee5946e85.webp)

For ERC-20 tokens, the contract address starts with “0x” and is followed by 40 characters. You can usually find it by looking up the token you want to trade on reputable websites like  [CoinGecko](https://www.coingecko.com/).

_Note: While rare, it is possible for token lists to show the wrong contract address. Always check the official channels of the project you are trading for the most up-to-date information on token contract addresses._

## Step 4

Once you’ve found the token you’re looking for, click the “Import” button to add it to CoW Swap.

![5-add-custom-tokens.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/5_add_custom_tokens_da75a6cce1.webp)

## Step 5

Ensure you’ve entered the correct token address and click “Import.”

![6-add-custom-tokens.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/6_add_custom_tokens_160c90e632.webp)

## Step 6

Once imported, you will be able to trade the token on CoW Swap. Tokens only need to be imported once per browser.

![7-add-custom-tokens.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/7_add_custom_tokens_149eafcaa6.webp)

CoW Protocol January 2024 Highlights

On February 9th, 2023, After a successful  [governance vote](https://www.tally.xyz/gov/ens/proposal/45461903078948131870051132081249892009497709518413744958551889217805827301425)  from ENS, CoW Swap processed a large trade for the ENS DAO using the exchange’s signature intent-based trading design and Milkman contract.

## Trade Details

[ENS DAO sold 10,000 ETH](https://twitter.com/CoWSwap/status/1623680760522612738)  in exchange for USDC in order to reduce its exposure to ETH.

-   **USD value of the trade**: $16,145,549.60
-   **Slippage tolerance:**  2%
-   **Actual slippage**: 0.5%
-   **Price surplus**: $80,992.87

## Why CoW Swap?

CoW Swap’s solver competition ensured that ENS received the best possible execution price, even after announcing trade details publicly in a governance proposal ahead of time.

CoW Swap provided several benefits for a trade of this size:

1.  Protection from attack vectors caused by the delayed execution
2.  Allowing ENS to create a governance proposal that includes the exact swap parameters and protects the trade with a price checker — guaranteeing that the trade receives some minimum amount determined at the moment of swap execution (not during the creation of the governance proposal)
3.  Use of the Milkman bot for protection against MEV, slippage, and re-entrancy risk

## Milkman

The CoW Grants Program-funded, and Yearn.fi-developed  [Milkman bot](https://github.com/cowprotocol/milkman-bot)  was critical to the ENS trade.

The Milkman bot ensures that trades execute for the real-time price or better by utilizing a price checker, such as a Uniswap v3 pool, Chainlink oracles, or a custom price checker. Instead of setting a slippage tolerance, DAOs can utilize Milkman to determine a maximum percentage deviation from the price checker, guaranteeing that their trade will finalize at a fair market price. Milkman also simplifies governance for trades as DAOs don’t have to define a fixed price re-vote if the market moves significantly.

For this swap, ENS DAO chose to use a Uniswap v3 ETH/USDC pool, with a maximum slippage of 2%, guaranteeing that they would receive no less than the minimum specified in the governance proposal.

## CoW Swap: The leader in DAO trading

The largest DAO trades take place on CoW Swap, and the exchange is single-handedly responsible for more than 30% of all DAO trades. Check out  [CoW Swap for DAOs](/learn/cow-swap-for-daos)  to learn why DAOs such as  [Aave](/learn/aave-trade-breakdown),  [Nexus Mutual](/learn/nexus-mutual-trade-breakdown), and more trust CoW Swap with their large trades.

ENS Trade Breakdown

CoW Protocol is proud to announce the launch of CoW Hooks. You can now implement custom-coded DeFi actions that execute directly before and/or after your trades.  **CoW Hooks can be used to chain together complex actions such as trading, bridging, staking, depositing, and much more.**

The best part?  **CoW Hooks execute your entire sequence as a single transaction and, true to the CoW Protocol model, you pay gas fees in your sell token if, and only if, your transaction succeeds.**

## Background

In recent months, the crypto industry has been absorbed in discussions on “intent” messages on Ethereum and the new possibilities that this innovation unlocks.

So far, the only production-ready intents system live on Ethereum is CoW Swap. The rest has only been theory and research papers covering the possibilities of intents. What’s more, these papers frame the user transaction as an “intent” but they don’t usually allow for composability. This is why the CoW Swap model asks the user to sign the trade instead of executing it directly on chain… This allows solvers to optimize the order by composing it with other strategies and optimizations. Composability unlocks the real power of intents, as they are meant to abstract the user away from complex interactions.

CoW Swap has been the leader in the intent space for a while and has built one of the most widely-used intent-based models. On CoW Swap, users delegate their trade execution to a network of solvers that complete the transaction on their behalf. This delegated trading model makes way for composability as solvers can batch trades together, find  [Coincidence of Wants](/learn/what-are-cows-on-cow-swap)  (CoW) matches, update the trading path at the moment of execution (rather than the moment of creation) and more.

Today, CoW Swap is proud to announce the launch of an overhauled intents system that allows for composability of a wide range of actions before and after a swap.

It’s called CoW Hooks.

## What are CoW Hooks?
![1-cow-hooks.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_cow_hooks_801e54dabe.webp)

CoW Hooks are arbitrary Ethereum “calls” that attach to an order and execute before and/or after the order. Developers and advanced traders can use code to express an intent that performs some action before a swap (pre-hooks) and after a swap (post-hooks).

**Pre-hooks**  can be used to “set up” conditions for an order. Examples include executing the code necessary for validating an on-chain signature, or setting the required approvals through an EIP-2612 permit.

**Post-hooks**  execute after a swap takes place and the receiver address receives the funds. Post-hooks provide an opportunity to put the funds to use immediately through staking, liquidity providing, bridging tokens to L2s, and much more.

## How do CoW Hooks work?

CoW Hooks let you do anything you can imagine. You can use whatever you can encode on-chain as a pre or post hook. The only requirement is that your action includes a trade on CoW Swap.

With CoW Hooks, users define:

-   A list of pre-hooks intents
-   The swap intent
-   A list of post-hooks intents

The flexibility of creating CoW Hooks opens up a world of possibilities — all you need to do is encode your actions in the right order for your particular use-case.

### Fresh Address Receives tokens: Permit, Swap & Bridge

Let’s say that you receive USDC and you would like to bridge the funds to another chain. You can use CoW Hooks to execute a token approval, swap, and bridge all at once.

-   **Pre-hooks**: Use a pre-hooks action to approve the token for a swap
-   **Swap**: Use CoW Swap to swap your USDC to the token you would like
-   **Post-hooks**: Send your new tokens to the bridge contract as a post-hook

And just like that, you have received, swapped, and bridged your tokens to a different chain all in one set of transactions. As a bonus, all of your gas fees will be charged in your sell token (USDC in this case,) which means that you can move your received funds without first sending ETH to cover gas costs.

If you are interested in learning more about the code behind this example, we’ve created a walkthrough on how to reproduce this exact set of actions in our CoW Hooks  [documentation](https://docs.cow.fi/overview/cow-hooks), as well as on YouTube:

### Flash Loan payback adapter for CDPs via Stop loss orders

You can also use CoW Hooks to repay debt or manage collateral levels. In this case, your hooks actions might look like this:

-   **Pre-hooks**: Approve the tokens you would like to swap
-   **Swap**: Use CoW Swap to swap for the tokens you need to service your debt
-   **Post-hooks**: Repay your debt and close your position, or use your tokens to add collateral so as to not be undercollateralized

We’ve also put together a walkthrough for how to code this set of hooks, you can view it here:

## Use CoW Hooks for everything

The examples illustrated above are just some of the uses of DeFi assets, but the possible use-cases for CoW Hooks are really endless. Here are some more examples:

-   **Repaying a debt & staking**: You could use CoW Hooks to repay a debt, close a position, swap assets for a yield bearing token, and stake your tokens all-in-one. To do this, you would set your pre-hook action to repaying the debt and closing the position, then you would use CoW Swap to swap your assets, and finally use a post-hook to deposit your new assets into a staking vault.
-   **Opening an LP position**: You can also work with only a pre-hook and a swap or only a post-hook and a swap. For example, if you wanted to open an LP position, you could first swap some assets for ETH, and then use a post-hook for the rest. If you wanted to do this via a CDP, you could deposit your ETH as collateral, borrow stablecoins, swap some stables to the other LP token side, and open a liquidity provider position.
-   **JIT (Just-in-time) smart orders**: Say that you want to leverage the benefits of programmable smart contract wallets to deploy a Safe and also trade via the composable CoW framework (ERC-1271). Using CoW Hooks, you can express the entirety of your transaction sequence at no cost. Connect the deployment of the Safe, execute your custom smart contract approval and swap, and even add on another post-swap action all in one. The entire sequence is conditional on every step being able to execute, otherwise none of it goes through.
-   **NFT sniping & selling:** CoW Hooks also come in useful in the NFT world. You can, for example, sell an NFT and encode a CoW Hooks action to immediately swap those funds for a token of your choice. Or, alternatively, you could place a limit order to purchase crypto at a certain price and then buy an NFT directly after.
-   **Bridging to another chain**: If you want to swap some tokens and bridge them to another chain, you could use CoW Hooks. In your flow, you would first swap your tokens and then send them to a bridge contract in order to combine both the approval and the bridging.
-   **Claiming airdrops**: While they’re not as common as they used to be, airdrops are a core part of many Ethereum projects. You can use CoW Hooks to sell your airdrops without spending any ETH on gas. Simply approve the token in your wallet and add a swap transaction to sell it. Your gas fees will be taken in the sell token, so you can enjoy holding on to your precious ETH.
-   **Unstaking and restaking**: If you’re an Ethereum validator and you want to claim your rewards, you’ll first need to unstake your 32 ETH in order to perform any action with them. With CoW Hooks, you can unstake your ETH, approve and swap to a token of your choice, and then re-stake your new assets somewhere else, all in a single set of encoded transactions.
-   **Automatically growing your LP position:** Let’s say that you’re a liquidity provider for a EUR — USDC pool on Gnosis chain that rewards you in GNO tokens. You can use CoW Hooks to automatically convert your GNO to EUR/USDC in a 50/50 split through CoW Swap and then use each of the assets to increase your LP position.

## What are you going to build with this anon?

The best part about CoW Hooks? They’re fully-featured and already live at the protocol level! So, if you are a developer or an advanced technical user, get your wallets ready and step into a new era in DeFi!

## Governance

It has been a hectic month in terms of governance; CoW DAO has executed 3 proposals! After a relaxing month of July, the CoWs came back in force for August 💪.

### Executed Proposals

This month we executed three important proposals:

-   [CIP 28 — Should CoW DAO send its profits to the CoW Treasury Core unit to generate extra revenues?](https://snapshot.org/#/cow.eth/proposal/0x269163793f84ceded1b4c902ca1d368e49f4c5991cb4780493feca2a0b640f1b)
-   [CIP-29: Renewal of the solver rewards program](https://snapshot.org/#/cow.eth/proposal/0x22fde20fee09167dbde2981a8e9b7552dcb67af887474b0005d15eedb2a8a6d9)
-   [CIP-30: Implementing oSnap for Optimistic Governance in CoW DAO](https://snapshot.org/#/cow.eth/proposal/0xbb52a603325a81e2f4e2cb0bb17d6626d8929737f2511d18e184cdeb94f7f3de)

### Draft Proposals

There has been a new proposal asking for feedback before moving into the next phase, a final CIP, in its current form:

-   [Fees and CoW bonding for MEVBlocker](https://forum.cow.fi/t/fees-and-cow-bonding-for-mevblocker/1876)

### Technical Discussions

As an “agora” for technical topics on batch auctions or CoW Protocol-related topics, the forum surfaced an interesting post:

1.  [Measuring and banning overbidding](https://forum.cow.fi/t/measuring-and-banning-overbidding/1874)

Make sure to read through it and leave comments — your feedback is highly appreciated and will help move important topics forward. If you are interested in submitting a proposal to the CoW DAO, make sure to use the following  [template](https://forum.cow.fi/t/cip-0-template/28).

CoW Protocol August 2023 Highlights

TWAP orders allow traders to spread their trade over a specified period of time in order to smooth out fluctuations in market price and open a position for an average market price. A TWAP order consists of multiple smaller orders placed at regular intervals over a predefined time period.

> **In our tests, selling 1,000 ETH in four parts of 250 ETH each, allowed us to yield a price for the order that was 3.5% better than selling the 1,000 ETH all at once!**

## TWAP Order Interface

To get started with TWAP orders through the  [Safe](https://app.safe.global/)  app, you will first need to authorise a transaction signing request that contains a batch of transactions (we’re big fans of gas savings through batching ⛽🚫). This batch includes a “setFallbackHandler’’ function. TWAP orders are the first order type that runs on a new conditional order framework, super-charging your Safe.

In order for this framework to make complex trades on your behalf, an upgrade to Safe’s “fallback  handler” is required. Don’t worry though, you will be automatically prompted to upgrade in order to use TWAP.

![1-twap.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_twap_9fef6b1d70.webp)


The TWAP interface has several sections:

-   **Trading Assets**: Select the assets you want to swap and the amounts of each.
-   **Price Protection**: Provides protection against major price movements. Your TWAP order won’t execute if the market price dips more than this percentage (calculated from the asset price at the time of order submission).
-   **Number of parts**: Enter the number of parts you would like your order split into.
-   **Total Duration**: The total amount of time your order will take to execute.
-   **Part Duration**: Automatically calculated from your total duration and number of parts, part duration shows how long CoW Swap will wait between each part of your order.
-   **Sell & Buy per part**: Shows an estimate of how much CoW Swap will sell and buy with each part of your trade.

## Benefits of TWAP Orders

TWAP orders have been widely explored through research literature in traditional finance but haven’t yet seen the light of day in DeFi. They’re finally entering use on exchanges such as CoW Swap and they provide a range of benefits for traders.

**Reduce your slippage**: Breaking up a large order into smaller pieces allows you to set a smaller slippage tolerance for each piece than if you had executed the large order as one.

**Reduce your price impact**: As with slippage, breaking up a large order into small pieces allows you to spread your liquidity needs over time, reducing your price impact.

**Always receive 100% of your order surplus**: On CoW Swap, all order surplus is forwarded to you. If your order executes for a better price than your quoted price — thanks to  [Coincidence of Wants](/learn/what-are-cows-on-cow-swap)  or any other price improvement that solvers are able to find — the extra price improvement will be forwarded to you.

**Eliminate market fluctuations**: By giving traders the time-weighted average price, TWAP orders smooth out market volatility, which makes trying to predict prices a thing of the past.

**Customise your order parameters**: TWAP orders allow you to fine-tune your order by specifying the number of parts you’d like it split up into, as well as the time period you want it to execute over. On CoW Swap, TWAP orders also have a “price protection” option which protects your order from executing at an unfavorable price due to market volatility.

## Get Started with TWAP Orders on CoW Swap

TWAP orders are now available in the  [CoW Swap order interface](https://swap.cow.fi/#/1/advanced)  under the “Advanced” tab.

**Have a Safe?**  Awesome! You can try out TWAP  [here](https://swap.cow.fi/#/swap?utm_source=medium&utm_campaign=TWAP-announcement).

**Don’t have a Safe?**  Not a problem! Create one  [here](https://app.safe.global/share/safe-app?appUrl=https%3A%2F%2Fswap.cow.fi&chain=eth).

The CoW Swap team is working on adding support for more wallets in the future.

One more thing to note: TWAP orders are most useful for big trades! So, when trading on Mainnet, the  _minimum_  TWAP order size is $5k. This minimum ensures that your savings from reduced price impact are not lost on execution fees (AKA gas fees). If you want to trade smaller amounts, head over to Gnosis Chain, where the TWAP order minimum is only $5 (and the gas fees are much cheaper!)

As always, on CoW Swap:

-   All prices are aggregated from the best available on-chain and off-chain liquidity.
-   Traders are fully protected from MEV.
-   Orders are free to place and free to cancel.
-   Traders never pay for failed transactions.
-   Transactions are gasless as fees are paid in the sell token.

Celebrating ComposableCoW’s conditional order superpowers, we are releasing it with TWAP (time-weighted average price) order support for enabled-Safe users.

CoW Swap is excited to announce the launch of Time-Weighted Average Price (TWAP) orders! Available now as an advanced order type in the CoW Swap order interface.


CoW Swap Launches TWAP Orders

CoW DAO is an open organization of developers, traders, market makers, and various community members aligned with the vision of providing traders with the best prices and comprehensive MEV protection. CoW DAO is focused on building and maintaining CoW Protocol, a fair and decentralized trading system, and MEV Blocker, an RPC endpoint. CoW Protocol’s technology powers a network of traders and solvers, enabling trustless and efficient peer-to-peer trading through a unique “batch auction” system. This positions CoW Protocol as native trading infrastructure for discrete-time settlement layers like Ethereum. MEV Blocker is designed to protect transactions from MEV attacks such as front-running and sandwiching. In addition to protecting trades from harmful MEV, MEV Blocker leverages an Order Flow Auction between various searchers and builders to offer rebates to users for certain trades.

[oSnap](https://uma.xyz/osnap)  is a DAO governance tool built and secured by  [UMA](https://uma.xyz/). It allows communities to vote off-chain and automatically execute the successful proposals on-chain. oSnap automatically integrates with the DAO’s  [Snapshot](https://snapshot.org/#/)  space and the Safe wallet holding the DAO’s treasury funds. Transactions approved by the community are validated on-chain and executed without the need for centralized multisig approval.

CoW DAO is looking forward to integrating oSnap, as it will give the DAO several advantages including:

-   A decentralized process to execute successful proposals that no longer requires the involvement of multisig signers → Instead of having the multisig owners push successful proposals on-chain themselves, the oSnap bot will automatically execute them
-   Extra on-chain guarantees through a challenge period → Through oSnap, voters will be able to challenge proposals during a “challenge period” that takes place after the successful passing of a proposal
-   One step closer to a more decentralized and resilient CoW DAO → Integrating oSnap allows CoW DAO to run 100% through on-chain governance without relying on any off-chain infrastructure or trusted parties

## How it works

On a technical level, Snapshot allows users to integrate transaction data into their proposals using its transaction builder tool. Community members can include specific transactions in their proposals for the DAO to execute. Once a proposal is published, Snapshot uses the decentralized hosting service IPFS to store and share this transaction data, assigning it a unique identifier in the process.

Once a proposal is approved, the oSnap system takes charge of submitting the transaction data to UMA’s optimistic oracle. The oracle then verifies that the transaction matches the data stored at the IPFS identifier. If the oracle confirms the match, the transaction is executed using funds from the DAO Safe. However, in the event of an invalid or malicious transaction, the system automatically removes the data before it reaches the blockchain.

This integration is a step forward for CoW DAO’s decentralization. If you are interested in participating in the CoW DAO governance process, you have several options:

-   [Forum](https://forum.cow.fi/)  → CoW DAO’s forum is the main venue for governance-related discussion. Signing up for the forum allows community members to post and participate in discussions.
-   [Snapshot](https://snapshot.org/#/cow.eth)  → CoW DAO’s Snapshot space is a simple voting interface that allows users to vote on proposals. Votes on Snapshot are weighted by the number of vCOW+COW held or delegated to the address used to vote.
-   [Discord](https://discord.gg/cowprotocol)  → The CoW DAO Discord server is currently the main discussion hub for the CoW community and an informal place for governance discussions. The “governance-discussion” channel is where governance matters and proposals are discussed.

CoW DAO integrates oSnap for decentralized governance


A DEX aggregator is a platform that searches multiple decentralized exchanges to find the best prices for crypto trades.

The rise of permissionless trading venues known as decentralized exchanges (DEXs) allow users to swap between virtually any cryptocurrency assets. Navigating multiple decentralized exchanges, however, can be cumbersome and inefficient.

This is where a decentralized exchange (DEX) aggregator comes in.

DEX aggregators are decentralized applications that search decentralized exchange trading platforms (like Uniswap, Balancer, and others) to find the best prices for any given trade. DEX aggregators have become pivotal to the world of decentralized finance (DeFi) by providing a single trading platform for users looking to get the best deal on their swaps.

## How does a DEX aggregator work?

DEX aggregators search various sources of liquidity to find the best trade route for on-chain assets.

Since liquidity is often fragmented across various sources, different decentralized exchanges may quote different prices for the same asset. DEX aggregators “aggregate” quotes from decentralized exchanges and fulfill user orders at the best available price. Sometimes, DEX aggregators may even route a single trade across multiple decentralized exchanges to reduce  [price impact](/learn/cow-protocol-glossary#:~:text=Price%20impact)  and provide better execution.

There are multiple types of DEX aggregators and the last few years have seen ever-more advanced versions of these platforms become available.

### Traditional DEX Aggregators

![1-what-is-a-dex-aggregator.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_what_is_a_dex_aggregator_b90efd4ea4.webp)

_1inch DEX Aggregator_

Traditional DEX aggregators such as 1inch have been around for years. Their interfaces look very similar to those of regular decentralized exchanges. A user is presented with a swap module that takes in two cryptocurrencies: a sell token and a buy token. After the user clicks “swap,” the aggregator automatically finds the best liquidity for the trade and executes the transaction on-chain.

### Meta DEX Aggregators

![2-what-is-a-dex-aggregator.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_what_is_a_dex_aggregator_2323d5b3ed.webp)

_DeFi Llama Meta DEX Aggregator_

Meta DEX aggregators are a step up from traditional aggregators. As the “meta” name implies, they aggregate DEX aggregators. This leads to better liquidity coverage across more venues, while still providing users with a single interface for their trades.

### Intent-Based DEX Aggregators

![3-what-is-a-dex-aggregator.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/3_what_is_a_dex_aggregator_198d1d6719.webp)

_CoW Swap Intent-Based DEX Aggregator_

Intent-based aggregators are the most advanced type of DEX aggregator out there.

They not only aggregate on-chain liquidity across exchanges and other aggregators, they also delegate execution to third parties known as “solvers.” These third parties provide additional sources of liquidity by including private inventory and, in certain cases, even matching trades peer-to-peer. This avoids protocol fees and makes for the most efficient trades in DeFi.

## Benefits of Using a DEX Aggregator

DEX aggregators provide a number of benefits, simplifying trading and providing better outcomes for users.

**Better Prices**: DEX aggregators look across multiple on-chain decentralized exchanges to find the best prices for any given token pair. Since most on-chain trading relies on  [automated market makers (AMMs)](/learn/cow-protocol-glossary#:~:text=amm), liquidity may be fragmented across various exchanges. As their name suggests, aggregators collect this liquidity in one place, giving traders the best deal for their swaps.

**Convenience**: By using a DEX aggregator, traders can reliably get good prices for their trades in one place without having to check multiple exchanges.

**Price Impact Protection**: Fragmented liquidity can sometimes make for shallow pools, meaning large trades experience significant  [price impact](https://blog.cow.fi/cow-protocol-glossary-ad7313a2c71#:~:text=Price%20Impact). Aggregators can break up trades across multiple exchanges, reducing price impact and providing better prices.

**MEV Protection**: In the case of intent-based DEX aggregators, solvers execute trades on behalf of users—protecting them from price exploitation in the form of  [maximal extractable value (MEV)](/learn/understanding-mev-protection).

Fragmented liquidity often makes finding the best route for trades difficult. DEX aggregators bring this liquidity back together and take the work of finding the best prices off the backs of users.

## What is the Best DEX aggregator?

There are a number of DEX aggregators on the market today. By market share, the most popular DEX aggregator is 1inch. However, when it comes to innovation, intent-based protocols like CoW Swap go the furthest.

## CoW Swap: The Leading Intent-Based Aggregator

![4-what-is-a-dex-aggregator.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/4_what_is_a_dex_aggregator_8768b6d9fb.webp)

CoW Swap is a leading innovator in the intent-based aggregator space. It’s the second most popular DEX aggregator after 1inch, and a leader among DAO & Safe wallets.

Whales and DAOs (as well as retail users) rely on CoW Swap as their aggregator of choice because CoW Swap does more than just aggregate liquidity. It also provides comprehensive  [MEV protection](/learn/understanding-mev-protection)  and enables price optimizations — such as  [CoWs](/learn/what-are-cows-on-cow-swap)  — that traditional aggregators can’t. Thanks to its intent-based architecture, CoW Swap supports 22 solvers that compete with each other to find the best prices for each user trade, and even provide price surplus on top.

While other aggregators claim to provide the best prices, CoW Swap’s architecture is built from the ground up to incentivize the best prices and the most surplus for trades, all in an easy-to-use, worry-free interface.

Decentralized exchange (DEX) aggregators are used to find the best prices for user trades


What is a DEX Aggregator

[MEV bots](https://www.blocknative.com/blog/mev-and-creating-a-basic-arbitrage-bot-on-ethereum-mainnet)  monitor pending transactions in the mempool and place their transaction ahead of others, capitalizing on the order of transactions within a block. This approach allows them to gain a significant edge, profiting from traders placing transactions. Frontrunning occurs when an MEV bot monitors the mempool for a trader’s pending transaction. Spotting a potential trade, the bot quickly duplicates the users transaction so that they can be the one to get the tokens or the opportunity that the user detected.

This issue permeates various blockchain ecosystems — from decentralized exchanges to non-fungible token (NFT) marketplaces.

According to recent  [data](https://dune.com/jhackworth/mevmevmev), over 2.7 million MEV transactions have been processed on Uniswap alone. This alarming statistic underscores the widespread and high-stakes nature of MEV exploitation.

## How frontrunning works

Frontrunning takes advantage of the open nature of the blockchain mempool, as anyone can view transactions. MEV Bots exploit this transparency to hijack trades. Here’s a basic rundown of the process:

1.  **Monitoring Pending Transactions:**  The first step involves monitoring the blockchain network’s mempool, a holding area for pending transactions. Here, frontrunners, who are often sophisticated bots, scan the mempool to identify transactions that can carry significant value that they want to snatch away or that could influence the price of a particular asset
2.  **Selecting Profitable Transactions:**  The frontrunner will analyze the potential market impact once such a transaction is identified. For instance, if a large buy order for a specific token is detected, the frontrunner knows that this transaction could increase the asset’s price once processed
3.  **Placing a New Transaction:** The frontrunner will initiate their buy order for the same asset, intending to get their transaction processed before the initially detected transaction. They typically give the validators a higher “tip” to execute their transaction first in the block in comparison to the target transaction

### Frontrunning examples

A notable example of DeFi frontrunning involves the notorious MEV bot named “[jaredfromsubway.eth](https://www.theblock.co/post/230218/jaredfromsubway-mev-bot).” In one case, a user,  [0x3a7822](https://zeromev.org/block?num=17508508), intended to trade 2 ETH for another token, $BOB. This trade was noticed by the bot jaredfromsubway.eth, which continuously monitors the mempool for transactions it could take advantage of.

Once the transaction entered the mempool, Jaredfromsubway.eth quickly executed its own transaction to buy $BOB with ETH, strategically placing it as the first in the block, and knowing that he would get the assets at a discount as the transactions behind will pamp the pricer. MEV allows validators to prioritize transactions that are of the most value to them. Consequently, the bot’s transaction, being the first one in the block, was confirmed ahead of the user’s transaction.

![1-frontrunning.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_frontrunning_6077287d3c.webp)

The frontrunning attack triggered an increase in the price of $BOB tokens due to the additional demand created before the user’s transaction was processed. When the user’s original order of 145M $BOB was executed, it was conducted at this now-inflated price, leading to user 0x3a7822 receiving way fewer $BOB tokens, hence losing out on the value they could have otherwise captured.

Jaredfromsubway.eth completed its MEV attack by  [selling](https://etherscan.io/tx/0xff31ba1a8a61933e0093bc4afba95018929e9e1599fec204a3f503c6b7851cb1)  its $BOB tokens at an increased price, resulting in a profit, a second move that made this MEV attack a  [sandwich attack](/learn/what-is-a-sandwich-attack-and-how-can-you-protect-yourself). In this scenario, the price slippage triggered by the frontrunning bot meant that user 0x3a7822 encountered a worse trade-off, ultimately making a loss while the MEV bot profited — an estimated gain of 0.1 ETH.

Another form of frontrunning would have been for example, if user, 0x3a7822 identified an liquidation opportunity faster than anyone else and sent its transaction to the mempool to get the discounted assets from the liquidation in the first place, then Jaredfromsubway.eth would have seen this and would have replaced the users transactions with the transaction of its own, but with a higher gas fee, and thus more likelyhood to get processed faster, and effectively stealing the opportunity of capturing value away from the user.

### How Harmful is Frontrunning?

While frontrunning may seem harmless or even clever to some, it can adversely affect individual traders and compromise the overall integrity of the Ethereum network. Here’s how:

1.  **Impact on Traders**: Frontrunning disrupts the fair operation of financial markets. By exploiting pending transactions, frontrunners manipulate market conditions to their benefit. This can lead to distorted prices, impacting regular traders who abide by market rules. What’s more, these traders miss out on the value they would have otherwise derived from their trades. But most importantly, frontrunning attacks prevent users from receiving the value of the trading opportunity they identified
2.  **Long-term Market Consequences**: Over time, persistent frontrunning can erode market confidence. As traders realize they are consistently at a disadvantage due to frontrunning, they may lose faith in the integrity of the market and choose to leave. This could result in diminished market participation and liquidity, both of which are critical for overall market health and efficiency
3.  **Network Effects**: Frontrunning can also have wider implications for the underlying network. It can cause network congestion, since unnecessary transactions in a block slow down transaction processing times

CoW Swap takes a firm stance against all forms of Maximal Extractable Value (MEV), including frontrunning, as they are detrimental to traders and the wider Ethereum ecosystem. CoW Swap was built to cultivate a fair and transparent trading environment that best serves the interests of all market participants.

### How to protect against frontrunning?

Mitigating frontrunning and other forms of MEV can pose a challenge, given the transparent and permissionless nature of the Ethereum blockchain. However, CoW Swap gives traders the necessary tools to outsmart the MEV bots:

1.  **Batch Auctions**: Instead of executing orders immediately, CoW Swap orders are gathered and grouped into collections known as “batches.”  [Solvers](https://docs.cow.fi/cow-protocol/tutorials/solvers), or the algorithms that provide an order settlement solution for a batch, compete to deliver optimized solutions. This batch auction method ensures all trades within a batch share the same uniform clearing price, preventing MEV Bots from reordering trades. Through batch auctions, CoW Swap affords traders the opportunity to pool liquidity among their orders, enabling users to trade directly with each other or access specialized markets to complete transactions that would otherwise be impossible to do in a peer-to-peer manner — this is known as  [Coincidence of Wants](/learn/what-are-cows-on-cow-swap)  (CoW)
2.  **MEV Blocker**:  [MEV Blocker](https://mevblocker.io/)  is a straightforward solution to the MEV problem. It is an RPC endpoint that protects all types of transactions from MEV. MEV Blocker organizes an auction among searchers, who are given the chance to backrun your transactions and forward up to 90% of the backrun value to the user. In exchange, they protect you from both frontrunning and sandwich attacks
3.  [**Use CoW Swap**](https://swap.cow.fi/#/swap?utm_source=medium&utm_campaign=frontrunning-article)**:** CoW Swap is a meta DEX aggregator that uses batch auctions and facilitates an efficient trading process, preventing all forms of MEV, including frontrunning

### The CoW approach to frontrunning

CoW Swap distinguishes itself in the trading ecosystem with its innovative and comprehensive approach to combating frontrunning and other MEV tactics, thereby creating a safer trading environment for users. The platform has meticulously crafted multiple layers of protection, each targeting a distinct aspect of the MEV issue.

The initial line of defense is  **Delegated Trade Execution**. In conventional DeFi platforms, every transaction a user initiates is instantaneously visible in the public mempool, providing an opportunity for searchers to exploit it. As opposed to other exchanges, on CoW Swap, users sign an “intent to trade” which protects them from directly interacting with the mempool. CoW Swap directs all intents through a network of decentralized ‘[solvers](https://docs.cow.fi/cow-protocol/tutorials/solvers).’ These solvers are responsible for securing the best execution price for your trades, while also shielding you from direct exposure to the public mempool, effectively making you undetectable to MEV bots. Moreover, CoW Swap harnesses the power of  [‘Coincidence of Wants](/learn/what-are-cows-on-cow-swap)’ (CoW). This allows the platform to match orders off-chain, fostering peer-to-peer trades that not only save on gas and liquidity provider fees but also substantially reduce the risk of MEV attacks by circumventing public liquidity pools. CoWs that don’t rely on on-chain liquidity pools eliminate a key opportunity for MEV exploits.

The platform also introduces a  **Uniform Clearing Price**  for all orders in a batch. In a typical decentralized exchange, simultaneous trades clear at marginally different prices in the same block due to sequential transaction processing. This provides an opening for MEV attacks. CoW Swap counters this by ensuring all orders within the same batch auction are settled at the same clearing price within a block. As a result, the order of transactions within a batch becomes irrelevant, effectively preventing MEV attacks and giving users in the batch a fair price.

CoW Swap’s strategy to tackle frontrunning hinges on eliminating opportunities for searchers to exploit trades. This helps maintain the integrity of user transactions and safeguards user value. By leveraging its unique batching technology, CoW Swap remains resilient against frontrunning and other MEV attacks.

### Trade safe from MEV on CoW Swap

Given the severity and frequency of MEV attacks, protecting your trades from MEV should be a top priority. CoW Swap offers unparalleled protection with its pioneering anti-MEV features, making it an invaluable tool for every trader.

Frontrunning is a crypto strategy exploiting blockchain’s transparency to extract value from a transaction.


What is Frontrunning

MEV or “maximal extractable value” is a hidden tax on all types of Ethereum transactions. Any time you make a DeFi trade, buy or sell an NFT, or lend tokens to a liquidity pool, opportunistic users known as “searchers” may manipulate your trades, resulting in unfavorable prices, failed transactions, and missed opportunities.

To date, MEV has been responsible for more than $1.3 billion in lost value for Ethereum users.

![1-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_what_is_mev_050181095d.png)

MEV is a complex phenomenon with multiple different causes. In this article we’ll take a deeper look at what causes MEV, how it affects traders, and how you can protect yourself.

## How Does MEV Work?

MEV is possible because validators are free to order blockchain transactions as they see fit in order to maximize their profits. Proof-of-stake (PoS) blockchains such as Ethereum use parties known as “validators” in order to ensure that the consensus rules of the blockchain are followed by all participants. Validators get randomly selected to add the next block to the blockchain. In this process, they determine what transactions are included in the block, and in what order.

![2-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/2_what_is_mev_04f9643567.png)

When you submit a transaction on Ethereum, it does not immediately get added to the next block. Instead, it first goes into the “mempool” which is the collection of all pending transactions. Validators then pull transactions from the mempool and add them to the next block when it’s time for it to be built.

Here is where the opportunity to extract value through MEV comes in.

Validators are not required to add transactions to the block in the same order that they were submitted by users, so searchers can pay validators a fee to order transactions in a specific way. For example, they can pay to have their transactions come first if they want to frontrun someone else, or they can pay to have their transactions come right after a specific transaction if they want to perform a backrun — both are types of MEV.

## Understanding MEV Terms

In order to get a solid grasp of how the different types of MEV work, we must first familiarize ourselves with the function of on-chain trading through decentralized exchanges (DEXs) along with some terms.

**Automated Market Makers (AMM)**: Automated Market Makers are trading mechanisms that allow traders to buy and sell assets in real time. Unlike traditional “orderbook” trading, which relies on counterparties for every transaction (you need a seller in order to buy and a buyer in order to sell), AMMs work by maintaining a constant ratio between the prices of two assets. For example, ETH and COW. AMMs use the formula “x*y = k” to determine a fair price based on the ratio between two assets (x and y) in the liquidity pool.

Any time a trade alters this ratio by depleting the supply of one asset and increasing the other, the prices of the assets adjust in order to preserve the established ratio. For instance, if a trader buys COW and sells ETH, the COW price rises, and the ETH price falls. The opposite happens when traders sell COW and buy ETH.

**Slippage Tolerance**: When placing a trade, traders set a “slippage tolerance” for their transactions, which represents the maximum price difference they’re willing to accept for their trade. For example, if ETH is trading at $2,000 and you place an order to buy ETH with a 5% slippage tolerance, you’re willing to buy ETH at up to $2,100. If ETH goes above $2,100, however, your trade will fail, as it’s outside your slippage tolerance.

Some slippage tolerance is always necessary because the prices of crypto assets are constantly fluctuating, so by the time your trade executes, the price may have moved. Setting your slippage tolerance too high, however, leaves room for searchers to exploit your trades.

**Price Impact**: Crypto markets, like all markets, are based on supply and demand. AMMs maintain “liquidity pools” of assets that they use to fill trades. Each trade drains some amount of this liquidity, moving the price of the asset. This price movement is known as “price impact.” The larger the trade, the bigger the price impact.

A trade of $100 ETH will not move the price of ETH very noticeably, since it makes up a tiny fraction of the available liquidity. A trade of $1,000,000 ETH however, will noticeably move the price of ETH.

**Transaction Reordering**: Blockchain transactions do not always enter the block in the order that they were submitted. Searchers can “bribe” the validators responsible for creating the block to get them to arrange transactions in a specific sequence. This transaction reordering is what makes all of MEV possible.

## The Different Types of MEV

Now that we’re familiar with the core concepts at play in MEV attacks, let’s take a look at the different types of MEV.

### Frontrunning

Frontrunning is a particular type of MEV that affects all forms of Ethereum transactions including trades, NFT mints, and more. Users can sometimes receive messages like “your transaction may be frontrun” on decentralized exchanges and it’s important to understand what this means.

![3-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/3_what_is_mev_fa9d5e5144.png)

Frontrunning occurs when a user makes a transaction but gets “front run” by an MEV bot who makes the same transactions ahead of them.

1.  **Monitoring Pending Transactions**: The first step involves monitoring the blockchain network’s mempool, a holding area for pending transactions. Here, frontrunners, who are often sophisticated bots, scan the mempool to identify transactions that can carry significant value that they want to snatch away or that could influence the price of a particular asset.
2.  **Selecting Profitable Transactions**: The frontrunner will analyze the potential market impact once such a transaction is identified. For instance, if a large buy order for a specific token is detected, the frontrunner knows that this transaction could increase the asset’s price once processed.
3.  **Placing a New Transaction**: The frontrunner will initiate their buy order for the same asset, intending to get their transaction processed before the initially detected transaction. They typically give the validators a higher “tip” to execute their transaction first in the block in comparison to the target transaction.

Frontrunning disrupts the fair operation of blockchain transactions, leading to distorted prices, value drain, and missed opportunities for everyday traders.

Read more about frontrunning in our article: “[What is Frontrunning](/learn/what-is-frontrunning)”

### Backrunning

Backrunning is another form of MEV that affects various Ethereum transactions, including trades, NFT mints, and more. Unlike frontrunning, backrunning takes advantage of transactions after they have been executed.

![4-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/4_what_is_mev_ebc0972169.png)

Backrunning occurs when a user makes a transaction that gets followed by an MEV bot executing a strategic transaction right after theirs in order to capture a price movement.

1.  **Monitoring Pending Transactions**: Like frontrunning, backrunning attacks begin with searchers monitoring the mempool for profitable opportunities. In particular, they are looking for transactions that cause a large price impact, as the backrunning attack involves capturing the arbitrage opportunity left behind after a large trade.
2.  **Finding a Transaction with a Large Price Impact**: Once a valuable transaction is identified, the searcher analyzes its impact. For instance, if a large sell order for a specific token is detected, the backrunner knows that this transaction could decrease the asset’s price once processed.
3.  **Capturing the Price Impact**: By placing a transaction directly after a previous, large transaction, the MEV bot can capture the price movement that the transaction causes on the AMM. The backrunner makes a transaction correcting this price impact and collecting the arbitrage in the process.

Backrunning is considered the least harmful type of MEV. While it still captures value, it does not do it at the expense of the trader. When done in isolation, it only captures leftover arbitrage after a large transaction moves an asset’s price.

Read more about backrunning in our article: “[What is Backrunning](/learn/what-is-backrunning-mev-attacks-explained)”

### Sandwich Attacks

Sandwich attacks are considered the most dangerous type of MEV as they extract the most value from users. A sandwich attack is a combination of frontrunning and backrunning for maximum profit on the part of the searcher.

![5-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/5_what_is_mev_f66a58a086.png)

Sandwich attacks occur when a user’s transaction gets trapped, or “sandwiched,” between two hostile transactions — one before and one after. As a result, the original transaction executes at a much higher price than necessary, leading to an inflated price for the original trader and a profit for the searcher placing the two extra trades.

1.  **Monitor Pending Transactions**: Like all other types of MEV, sandwich attacks begin with searchers monitoring the mempool for profitable opportunities. In this case, they’re looking for trades that will create a large price impact which they can frontrun, capturing the value of the asset before the large transaction, and then backrun after the victim transaction, capitalizing on the price impact.
2.  **Perform a Frontrunning Transaction**: When a large trade is identified, the searcher will duplicate it and place their own transaction right before the victim’s — in essence frontrunning. The searcher gauges the size of their transaction to cause just enough price impact to push the asset’s price up to the precise slippage tolerance the victim has set.
3.  **Execute the Victim Transaction**: Since a sandwich attack is a 2-part process, the searcher orders transactions so that the victim’s transaction executes right after the seracher’s frontrunning transaction, but just before their backrunning transaction.
4.  **Execute a Backrunning Transaction**: After the victim transaction executes, its price impact pushes the price of the asset even further (remember it was already raised as a result of the searcher’s frontrunning transaction). Once this takes place, the searcher executes a backrunning transaction, selling the asset and profiting from the arbitrage.

Sandwich attacks are the most common types of swap-related MEV, taking advantage of a user’s slippage tolerance to cause maximum pain for the trader and maximum profit for the searcher.

### Loss-Versus-Rebalancing (LVR)

Loss-versus-rebalancing (LVR) is a type of MEV that affects liquidity providers (LPs) and accounts for more value loss than all other types of MEV combined.

LVR is different from the swap-based versions of MEV we’ve covered so far. It occurs when liquidity providers lose out on potential profits due to stale prices. Many liquidity providers haven’t even heard of LVR, but it costs them 5–7% of their liquidity, resulting in hundreds of millions lost each year. In fact, when accounting for LVR, many of the largest liquidity pools are not profitable for LPs at all.

![6-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/6_what_is_mev_39dc2a4798.png)

_(_[_Source: Delphi Digital_](https://members.delphidigital.io/learn/loss-versus-rebalancing-lvr)_)_

LVR is a form of arbitrage that occurs whenever an AMM has an outdated (stale) price in comparison to some other trading venue. Arbitrageurs exploit this price difference by trading from the AMM to the more liquid exchange (usually a centralized exchange like Binance), correcting the arbitrage and extracting value from LPs in the process.

Learn more about LVR in our article: “[What is Loss-Versus-Rebalancing (LVR)?](/learn/what-is-loss-versus-rebalancing-lvr)”

### Other MEV

Since the definition of MEV is broad enough to encompass all validator activities that maximize the profits of a given block, there are many other types of MEV that we haven’t covered here as well.

One such example is “Oracle Extractable Value” (OEV) which occurs whenever data from an oracle (such as pricing information) is outdated and searchers can capitalize on this arbitrage at the expense of regular users.

## An Example of an MEV Attack

Let’s take a look at a sample MEV attack through the example of the most common type of MEV — the sandwich attack. In this example, we’re going to be trading ETH and COW.

![7-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/7_what_is_mev_d8784b4c5e.png)

**Step 1**: Bessie wants to buy COW using her ETH. She goes to a decentralized exchange (DEX) like Uniswap, and places an order for 4,000 COW. This should cost her around 1 ETH, but due to significant market volatility, Bessie decides to set a 10% slippage tolerance. This means she’s willing to pay up to 1.1 ETH for 4,000 COW.

**Step 2**: Bessie’s trade enters the Ethereum mempool (the pending order queue), and a lurking searcher spots an opportunity. Springing into action, the searcher places a trade just before Bessie’s trade that is large enough to push the COW price up to her slippage tolerance. In this case, the searcher buys 4,000 COW for exactly 1 ETH. As a result of this first trade’s price impact, Bessie’s 4,000 COW purchase now costs 1.1 ETH — the maximum she’s willing to pay.

**Step 3**: Once the searcher’s transaction clears, Bessie’s transaction also goes through and she receives her 4,000 COW in exchange for 1.1 ETH. The searcher takes advantage of this price impact and sells his original COW at this new rate — 4,000 COW for 1.1 ETH.

In the end, the searcher buys 4,000 COW for 1 ETH and sells it for 1.1 ETH, earning a profit of 0.1 ETH (before gas and fees) for not much effort.

It’s easy to see how lucrative sandwich attacks are!

Bessie, on the other hand, ends up with a bad deal. She could have purchased 4,000 COW for just 1 ETH, but her slippage tolerance left room for a sandwich attack that forced her to pay an extra 10% for her trade.

## Why is MEV Bad?

MEV is a complex and often controversial topic in the Ethereum community.

Some say that MEV is a natural part of the Ethereum market mechanism and it helps to find the most efficient prices. Others believe that MEV can be harmful, but only if it’s concentrated in the hands of a few validators — therefore they work to “democratize” MEV and allow anyone to extract value from on-chain transactions.

However, MEV makes money for searchers, block builders, and Ethereum validators at the expense of regular users… especially beginners who don’t know how to protect themselves. As of the time of writing, sandwich attacks on AMMs and aggregators alike generate [almost $1 million in profit for searchers each week](https://eigenphi.io/mev/ethereum/sandwich).

![8-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/8_what_is_mev_26ab0ff9ec.png)

Over time, persistent MEV erodes market confidence as traders realize they are at a constant disadvantage to more sophisticated actors. Ultimately, MEV may pose an existential threat to blockchain ecosystems like Ethereum so it’s imperative for solutions to emerge that protect everyday traders from price exploitation.

## How to Protect Yourself from MEV

There are multiple ways to avoid MEV as a trader. The most comprehensive solutions take place at the dApp level, but not all dApps provide MEV protection so there are more all-encompassing protection methods including RPC endpoints.

### Reduce Slippage

The most basic defense against MEV is setting a low slippage tolerance.

Since MEV relies on slippage for price manipulation, transactions with a lower slippage tolerance give searchers less room to exploit trades.

For users who aren’t utilizing any other MEV protection tools, setting a lower slippage tolerance can be a good first line of defense, however it’s by no means a complete solution. Setting the slippage tolerance too low often results in failed transactions. Even with optimal slippage, MEV bots may still be able to extract value from your trades.

### Use a Custom RPC Endpoint

![9-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/9_what_is_mev_70787de2c8.png)

A better protection method is to install an MEV protection RPC endpoint.

A Remote Procedure Call (RPC) endpoint is an intermediate layer that routes transactions from a user’s wallet to the blockchain itself. Transactions pass through RPC endpoints before getting to the mempool, so RPCs can provide additional functionality across any blockchain application or protocol.

Normally, RPCs are a boring piece of blockchain infrastructure. Recently, however, specialized RPCs have begun incorporating extra security guarantees for transactions before they reach the blockchain.

One of the most popular specialized RPC endpoints is [MEV Blocker](https://cow.fi/mev-blocker). As the name suggests, MEV Blocker provides protection against MEV across all of Ethereum. The RPC works by managing a permissionless network of searchers and hiding transactions from the public mempool. These searchers cannot frontrun or sandwich user transactions. Instead, they capture value through backrunning. Anytime a searcher backruns a user’s transaction, the searcher keeps up to 10% of the value and sends the other 90% back to the user as a rebate.

Install MEV Blocker here: [https://cow.fi/mev-blocker](https://cow.fi/mev-blocker)

### Use an MEV-Protected DEX

![10-what-is-mev.png](https://celebrated-gift-f83e5c9419.media.strapiapp.com/10_what_is_mev_16deedca85.png)

As MEV has become more prevalent, decentralized applications (especially decentralized exchanges) have begun offering creative protection solutions to users. For example, many DEXs offer an “auto-slippage” feature which determines the optimal slippage for user trades, reducing the chances of price exploitation.

[CoW Swap](https://swap.cow.fi/#/) is a meta DEX aggregator that finds the best prices for trades and provides comprehensive MEV protection. The protocol uses a unique trading mechanism that relies on batch auctions and intents to achieve the best outcomes for users. Thanks to a powerful combination of delegated trade execution, batch auctions, and protected transaction flow through MEV Blocker, CoW Swap users benefit from thorough MEV protection on all trades.

## Maximal Extractable Value — Ethereum’s Existential Battle

MEV is a critical problem for the Ethereum ecosystem because it undermines the fundamental principles of fairness and transparency that blockchain technology aims to uphold. The ability of sophisticated actors to extract value from everyday traders pushes users away and discourages the broad adoption of decentralized technologies.

Addressing — and eventually solving — MEV is essential to keeping Ethereum a robust, innovative, and user-friendly platform for all participants. To this end, CoW DAO is working hard to secure a decentralized future by creating products that ensure a fair and protective decentralized financial system.

CoW DAO March 2024 Highlights

Maximal extractable value (MEV) has become a controversial topic in the DeFi community over the last few years as the practice has gained wider adoption. Some blockchain projects take steps to protect their users from suffering MEV, but there are also advocates of the practice who argue that it contributes to market efficiency and validator compensation.

[CoW DAO](https://cow.fi/)  creates products that protect Ethereum users from negative outcomes, so it’s clear that participants in the DAO are no fans of MEV. The technical innovations that MEV searchers have pioneered in the pursuit of maximizing profits, however, are indeed impressive.

Thankfully, this tech can be put to good use in a way that benefits users and still makes money: Rather than being MEV searchers, these users should consider becoming CoW Protocol solvers.

## What is a Searcher?

Searchers are DeFi market participants, most often bots, that monitor pending Ethereum transactions for arbitrage opportunities.

Captured arbitrage is known as  [maximal extractable value (MEV)](/learn/understanding-mev-protection), and it’s a pernicious form of price exploitation that occurs across all types of transactions. To date, MEV has cost traders over $1.5 billion in losses. Most of these losses have been facilitated by searchers who pocket a large portion of the arbitrage for themselves.

## What is a Solver?

![1-switch-from-searcher-to-solver.webp](https://celebrated-gift-f83e5c9419.media.strapiapp.com/1_switch_from_searcher_to_solver_7763c26103.webp)

CoW Protocol is a meta DEX aggregator that relies on bonded third parties known as “[solvers](https://docs.cow.fi/cow-protocol/concepts/introduction/solvers)” to execute user trades. The protocol uses an  [intents-based trading system](https://docs.cow.fi/cow-protocol/concepts/introduction/intents)  where user intents get grouped into  [batches](https://docs.cow.fi/cow-protocol/concepts/introduction/batch-auctions). The solver that can execute the orders at the best price wins the right to settle the batch (find out more about how CoW Protocol works  [here](https://docs.cow.fi/category/concepts).)

Solvers are compensated in COW tokens for settling batches, incentivizing them to compete to find better prices and win the right to execute user intents. In return for this compensation, solvers provide users with a number of benefits including:

-   Finding optimal prices for the trades in a batch
-   Protecting users from MEV by executing transactions on their behalf
-   Providing abstraction that allows for benefits like gasless trades, transaction bundles, directly tapping into LPs, and more

## Searchers vs. Solvers

Fundamentally, searchers and solvers optimize for the same thing: maximizing profits. However, they serve different purposes, so their incentives diverge.

Searchers make money by performing MEV attacks on vulnerable transactions — giving users worse prices and keeping the difference for themselves. Searchers are incentivized to maximize their profits while ensuring that they are bidding enough for their transactions to be included in the next block.

In Ethereum, searchers work to out-bid each other to have their transactions included and make money. This is similar to what solvers do on CoW Protocol. The difference, of course, is that  **searchers benefit validators while solvers benefit users.**

## Why Become a Solver?

The fundamental difference between searchers and solvers is that searchers extract value from user transactions while solvers add value to them.

MEV may be a profitable enterprise in the short-term, but it hurts users and makes for a more toxic ecosystem. This turns potential new entrants away, feeding a vicious cycle — after all if there are no users left, who will searchers make money off of?

Solvers are the opposite: they take the same tech but they leverage it for the benefit of users. This cycle is virtuous, rather than toxic. Users achieve better prices, so they’re incentivized to use the product more, which means more order flow and better compensation for solvers.

From a technical standpoint, the methods searchers use to find arbitrage opportunities can be used to instead find solutions to batches. Searchers can leverage their existing nodes, algorithms, servers, AMM-indexed liquidity, simulation services, and more to become a good solver. This means that the lift to turn a searcher into a solver is relatively minor, while the upside is significant.

## Who can be a Solver?

CoW Protocol was the first DEX to implement intent-based trading, a model that the entire DeFi industry is now moving towards. This means that  [opportunities for solvers](https://dune.com/cowprotocol/solver-info)  will only grow in the coming years.

Thanks to a permissionless structure, anyone can become a solver. The main requirement is to put up a bond which serves as a guarantee that the solver will follow the  [rules](https://docs.cow.fi/cow-protocol/reference/core/auctions/competition-rules)  or risk getting slashed.

Solvers that do well find good solutions to the  [batch auction problem](https://docs.cow.fi/cow-protocol/reference/core/auctions/the-problem). They also generally:

-   Develop an efficient optimization algorithm
-   Identify and solve special problem instances that are easy to solve
-   Consider diverse liquidity sources
-   Integrate external market makers

## How to Become a Solver

Transforming a searcher setup into a solver setup or writing a new solver takes some technical expertise. We won’t go into it in this article, but you can find the requirements and specifications for becoming a solver in the  [CoW Protocol solver documentation](https://docs.cow.fi/cow-protocol/tutorials/solvers).

We also answer questions and provide technical support through the CoW Protocol  [Discord](https://discord.gg/cowprotocol).

Happy solving!

Welcome back to another monthly CoW update, where we break down the most notable developments of the last few weeks at CoW Protocol.


CoW Protocol October 2023 Highlights

**Overview**

-   Many Ethereum traders receive suboptimal prices and face risks from MEV bots when trading on traditional decentralized exchanges (DEXs)
-   CoW Swap is a solution that provides price improvement technology to ensure traders get the best possible prices on their trades while also enjoying MEV Protection
-   CoW Swap uses batch auctions to find the optimal clearing price for all trades in a batch, as well as  [Coincidences of Wants (CoWs](/learn/what-are-cows-on-cow-swap)) that enable peer-to-peer transactions, among other types of optimizations
-   CoW Swap improves pricing and increases market depth, providing traders with greater access to liquidity and better overall trading conditions

For far too long, Ethereum traders have been forced to deal with suboptimal pricing when trading tokens.

Unfortunately, many traders are unaware they may receive a bad deal on their trades when using traditional Decentralized Exchanges (DEXs). To make matters worse, some traders may also fall victim to manipulative MEV bots, whose damages total billions of dollars in exploited value.

## How does CoW Swap work?

_Figure 1: Showing how Batch Auctions work on CoW Swap_

CoW Swap has introduced a revolutionary approach to trading: A delegated trading model through an Order Flow Auction that runs on “batch auctions” to find the best settlement for all the trades.

When using batch auctions, traders submit their intent to trade a particular token pair without having to settle their raw Ethereum trades directly on-chain, as the  [solvers](https://docs.cow.fi/cow-protocol/tutorials/solvers)  (auction settlers) will be the ones creating the transaction for them. This innovative approach means that traders don’t have to fine-tune their own trading parameters — such as what liquidity pools to use and what slippage to set — all while enjoying better prices and MEV protection.

Unlike traditional DEX orders, intent-based trades protect traders from getting MEV’ed. This ensures that traders can execute their trades with greater confidence, security, and efficiency while getting the best possible price. With CoW Swap, users can trade without worrying about the typical pitfalls of trading on a DEX, and rest assured that any price improvement is forwarded to them (not kept by the protocol.)

### What is price improvement?

CoW Swap is revolutionizing how traders approach decentralized exchanges by providing price improvement technology (in the form of “surplus”) that ensures they get the best possible price on every trade.

Once a trader submits an intent to trade by submitting a signed order, it gets sent to an off-chain orderbook and inserted into a batch auction where solvers can search all available on-chain liquidity to find the optimal order clearing price. CoW Swap’s batch auction mechanism helps improve pricing by batching orders together and establishing a uniform clearing price. By doing this, CoW Swap creates a more liquid trading environment that matches  [Coincidences of Wants (CoWs)](/learn/what-are-cows-on-cow-swap)  and finds other optimizations which improve the trader’s price.

CoWs enable traders to conduct peer-to-peer transactions directly with each other, eliminating the need for intermediary AMM pools and providing a more efficient trading price.

Many times, CoWs allow traders to entirely bypass any on-chain liquidity and directly exchange tokens, avoiding slippage and any fees they might incur. In the trading UI, CoW Swap quotes the minimum price the trader will receive whenever the trade executes. In most cases, CoW Swap forwards price surplus to traders by giving them more of their purchase tokens.

_Figure 2: Showing CoW Swap’s UI_

To illustrate the power of CoW Swap, let’s take a look at  [this CoW Swap Batch Auction Settlement](https://explorer.cow.fi/tx/0x0e9877bff7c9f9fb8516afc857d5bc986f8116bbf6972899c3eb65af4445901e?tab=orders).

In this settlement, 8 different trades were executed in a single batch, forming a CoW and also leveraging the best possible on-chain liquidity for all traders involved. If we take a close look at the settlement, we can see that some USDC-ETH traders are overlapping meaning a portion of their trade can be matched directly in a CoW instead of tapping into an AMM. For the rest of the trades, the settlement tapped into the best on-chain liquidity available.

Thanks to the batch auction mechanism, CoW Swap provided all traders with a surplus on top of their quoted price, maximizing their returns and minimizing their exposure to risks. In this example, the average surplus was 1.66%, giving traders a bunch of extra tokens than no other DEX can give since these price improvements are only possible by leveraging batch auctions as a trading mechanism.
