CoW Swap uses batch auctions to protect traders from MEV (Maximal Extractable Value) attacks.​ The protocol works by having solvers compete to find the best execution prices across decentralized exchanges.​

How it works:

  • Trades are grouped into batches rather than executed individually
  • Multiple solvers compete to provide optimal pricing
  • This structure prevents front-running and sandwich attacks by predatory bots

Key benefits:

  • Protection from MEV extraction during normal trading
  • No gas fees lost on failed transactions
  • Competitive pricing across all DEX liquidity sources

The batch auction model proved particularly effective during recent market volatility, when MEV bots extracted millions from traders on traditional AMMs while CoW Protocol users avoided these costs entirely.​
