The Settlement Layer for Decentralized Trading
CoW Protocol lets people swap assets MEV protected at the best exchange rate by leveraging its batch settlement layer built on top of DeFi’s favorite AMMs and DEX Aggregators. Instead of directly executing trades on-chain, users only sign their swap intention and delegate the execution to so-called solvers (aka relayers in other protocols). Solvers bid on the best possible exchange rate in order to win the right to settle trades. By batching multiple trades together in order to create CoWs (Coincidence of Wants), solvers can save on gas costs, AMM fees and execution risk. Therefore CoWs lead to structurally better prices than on any existing DEX aggregator. In the absence of CoWs solvers fall back to using the best possible on-chain route, by comparing quotes from leading aggregators.
- Trades: 4
- Saved fees: $1,392
Traders swapped 99.39% peer-to-peer, while the remainder was executed on Sushiswap
If they had traded by themselves, they would have paid $1,396 in liquidity fees in Sushiswap; instead they paid 8$.

More than a Meta DEX Aggregator
- Best On-Chain Prices
By leveraging any on-chain liquidity sources we are able to provide the best on-chain prices.
- Professional Transaction Execution
Meta-transactions ensure that traders do not pay for failed transactions. They also facilitate automatic resubmission of failed orders.
- Coincidence of Wants (CoWs)
CoWs, simply put as peer-to-peer trades, improve the prices by reducing the need for liquidity pools. This saves the traders money spent on protocol fees, slippage, and gas fees.
- MEV Mitigation
Trades are protected against MEV in multiple layers: via Coincidence of Wants (CoWs) and leveraging both Flashbots Protect RPC and the Eden Network.
- Same Block, Same Price
All trades within the same block are guaranteed to receive the same price regardless of their execution order.
- ETH-less Trading Experience
Traders pay fees in their sell tokens. No need to spend your precious ETH.
The life cycle of a CoW order
The protocol improves prices for traders by batching trades, finding Coincidence of Wants (CoWs)
and tapping into all on-chain liquidity, including aggregators. Read More
