CoWSwap vs Uniswap

CoW Swap is a decentralized exchange interface built on CoW Protocol, an intent-based meta-DEX aggregator that optimizes trades through batch auctions and a competitive network of solvers. Instead of executing swaps directly on-chain, users sign trade intents that are aggregated and matched via Coincidence of Wants (CoWs) or routed across multiple liquidity sources to achieve the best price. This architecture reduces slippage, captures price improvements, and protects users from Maximal Extractable Value (MEV). CoW Swap combines peer-to-peer matching with aggregated liquidity, enabling efficient, secure, and gas-optimized trading across multiple EVM networks.

Uniswap V4 rebuilds the protocol as a ‘Singleton’ contract and introduces programmable ‘hooks’ that let pools execute arbitrary logic before and after swaps. The redesign cuts gas costs by 15‑25 % and should open the door for new order types like TWAMMs and on‑chain limit orders. V4 is expected to go live shortly after Ethereum’s Pectra upgrade, when core devs will freeze the code under a Business Source Licence.
