What is Surplus?

On CoW Swap, we call any improvement over your quoted price “surplus”.

  • Positive Slippage: Sometimes the market moves to your advantage and the asset you’re trading becomes cheaper between the time you’re quoted and the time of execution. On CoW Swap, that price savings is passed on to you
  • Coincidence of Wants (CoWs): If your order is matched peer-to-peer with someone else, you save on gas costs and LP fees. That price surplus is also passed along to you
  • Any other price improvement: If the solvers can find a better source of liquidity than they originally quoted, or improve the price in any other way, this price improvement is forwarded to you.

CoW Swap Passes Along the Most Surplus

CoW Swap is the only exchange that passes along all types of price improvements. Positive slippage, gas savings, and other optimizations usually end up in the protocol treasury for most DEXs and DEX aggregators. At CoW, we put our users first, so you can rest assured that if we find a better price, it’ll be you we tell first.
