Plain English
CoW Swap (Coincidence of Wants) is a unique DEX aggregator that batches all incoming orders into discrete auctions every few minutes. Solvers compete to fill the entire batch; users get uniform clearing prices. The design eliminates sandwich attacks and most MEV by construction.
How it actually works
Orders sit off-chain until the next batch settles. The protocol matches “coincidences of wants” directly (if you’re selling ETH and someone else is buying ETH, you match P2P with no slippage). Remaining orders fill on-chain via solvers. MEV protection is structural rather than just protective routing.
What it means for you
CoW Swap is the MEV-conscious choice for any swap that doesn’t need instant fill. The trade-off: orders take a few minutes to settle (vs instant on 1inch/Matcha). For HNW size where saving 0.1–0.5% to MEV outweighs the wait, CoW Swap usually delivers the best net price. Always use it for trades above $50K.
