CowSwap is a MetaDEX aggregator. But what does the COW in CowSwap really stand for? COW comes from Coincidence of Wants, a phenomenon where two parties can exchange items directly without the aid of a third-party exchange. Think of people waiting in line at a currency exchange swapping between themselves instead of using the exchange. Users of CowSwap benefit from:

  • Gasless trades
  • MEV Protection
  • Best on-chain prices available
  • No gas fees charged for failed transactions

Users of the Balancer trade interface also benefit from these points, achieved through the Balancer-CowSwap-Protocol (BCP). The BCP uses CoW Solvers that integrate with the Balancer Vault to execute trades in batches. The solvers look for the optimal execution path for a trade to benefit the user.
