CoW Protocol

CoW Protocol receives a B risk grade (26/100) from Hindenrank, where lower scores indicate lower risk. Lower risk — genuine MEV protection and clean history, but solver concentration could quietly erode the execution quality you expect A trading protocol that protects you from front-running by batching trades together every 30 seconds and matching buyers with sellers directly. It processes $9B+ in monthly volume with $50M in deposits. Its B grade reflects a clean track record and strong MEV protection, limited mainly by the risk that a few dominant solvers could quietly degrade your execution.

The key risks identified for CoW Protocol are: (1) A small number of solvers handle most trades. If they collude, your trades get worse prices without you noticing. At $9B monthly volume, even 0.1% extraction costs users $9M per month (2) You approve the settlement contract to spend your tokens. If that contract gets hacked, all your approved tokens are at risk, not just what you are currently trading (3) The 30-second batch window means your order information exists briefly before execution. If it leaks, someone could trade against you despite the MEV protection claims
