About Co
W DAO

Co
W DAO is on a mission to protect Ethereum users from MEV and optimize trade execution across De

With over 100
- source repositories on Git
Hub, we're transparent,
- driven, and deeply committed to the
- source ethos. Our
- time Dune Analytics dashboard showcases billions in cumulative trading volume and a rapidly growing user base. As we continue to scale, Co
