How Do Decentralized Exchanges (DEXs) Try to Prevent Sandwich Attacks at the Protocol Level?

Some DEXs implement anti-MEV mechanisms directly into their smart contracts. This includes using batch auctions where all orders are executed at a single clearing price, removing the priority advantage of gas fees.

Other DEXs use private order flows or commit-reveal schemes. Additionally, some protocols incorporate 'Maximum Value Extraction' (MVE) protection, which may involve subsidizing users who were successfully attacked to compensate for their losses.
