ABOUT COW DAO CoW DAO is on a mission to build the most robust, user-protective, and efficient trading infrastructure in DeFi. We are the creators behind CoW Protocol (the engine behind CoW Swap). Operating as a dominant player in DeFi, CoW Protocol recently crossed a massive milestone of over $200 Billion in lifetime trading volume and consistently ranks as a top-two DEX aggregator by market share. Through combinatorial batch auctions, a competitive network of "solvers," and our unique Coincidence of Wants (CoW) matching engine, we protect traders from MEV bots and secure the absolute best execution prices on the market.
