[CoW Swap Upgrades Matching Infrastructure to Strengthen Solver Bidding] According to an announcement from CoW DAO, CoW Swap has launched two solver infrastructure upgrades to enhance the bidding mechanism and optimize the execution process. The first update is 'hidden bidding until the deadline,' where solvers cannot see each other's bids during the auction and can only submit blind bids before the deadline. This helps maintain strategy independence and improves user transaction outcomes. The second update removes the UCP (Uniform Clearing Price) constraint, a mechanism considered to add restrictions at the system level without providing additional benefits to users. Its removal simplifies solver logic, allowing the best solution to prevail more efficiently. The team stated that this move aims to improve matching efficiency while maintaining price consistency among users trading the same pairs.
