Batch Auction

A trading mechanism that collects many orders over a short window and settles them together at a single uniform clearing price, instead of matching them one by one. Because everyone in the batch gets the same price regardless of timing or order, the incentive to front-run or sandwich within the batch disappears — a structural MEV defence used by protocols like CoW Protocol (often via competing solvers). The trade-off is waiting for the batch rather than executing instantly, plus reliance on the settlement mechanism.
