CoWSwap vs Lighter

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.
