About CoW Protocol
CoW DAO is on a mission to protect Ethereum users from the dangers of DeFi. It does this by supporting the development of CoW Protocol, CoW Swap, MEV Blocker, and CoW AMM, and by funding values-aligned projects through the CoW Grants Program.
CoW Protocol is the second-largest DEX aggregator by monthly volume and the first-largest intents-based exchange. MEV Blocker is currently involved in ~4% of all Ethereum transactions, making it the category leader. CoW AMM is the only live AMM that protects LPs from LVR (loss-versus rebalancing).
As a member of CoW DAO’s core team, you will have the opportunity to shape these essential products, and contribute to the Ethereum ecosystem more broadly.
