MEV (Maximal Extractable Value) bots are automated programs that monitor blockchain transactions to profit from price differences and user trades.​

Key points about MEV bots:

  • They scan mempool for profitable trading opportunities
  • Common strategies include frontrunning and sandwich attacks
  • Can significantly impact regular traders' transaction costs

CoW Protocol offers protection against MEV through:

  • Batch auctions
