CowSwap is a decentralized finance application for the Ethereum blockchain. CowSwap tries to settle buy and sell orders between its users, i.e., find a coincidence of wants (CoW), which prevents slippage and fees.  Orders that fail to find a peer-to-peer match are sent to CowSwap's underlying automated market maker. CowSwap enables its users to execute trades at the best price on-chain across all exchanges and aggregators, such as Uniswap and Sushiswap.
