About CoW DAO

CoW DAO is on a mission to protect Ethereum users from MEV and optimize trade execution across DeFi. We achieve this through the CoW Protocol, CoW Swap (a leading intent-based DEX aggregator), and the innovative MEV Blocker, which together help secure, aggregate, and route trades for optimal outcomes. We also fund values-aligned projects via the CoW Grants Program.

CoW Protocol is consistently ranked among the top DEX aggregators by monthly volume and is the largest intent-based exchange. Our MEV Blocker protects trades from harmful MEV extraction and is integrated across the Ethereum ecosystem. The CoW AMM is the only live AMM designed to protect liquidity providers from LVR (loss-versus-rebalancing).

With over 100 open-source repositories on Dune Analytics dashboard showcases billions in cumulative trading volume and a rapidly growing user base. As we continue to scale, CoW DAO remains at the forefront of DeFi innovation, prioritizing security, efficiency, and decentralization.
