Cow Swap is a novel Meta Dex aggregator with MEV Protection
  • Lower prices thanks to CoWs (Coincidence of Wants) CoW Protocol matches trades peer-to-peer where possible, cutting out the middleman (liquidity fee)
-Never pay more than the cheapest alternative. CoW Protocol searches all DEXes (1inch, Uniswap or other exchanges) for you, so you get the best price available.
Protection from MEV, CoW Protocol is the industry leader in protecting users from frontrunning and sandwich attacks, which lose traders thousands of dollars every day. It does this by matching trades peer-to-peer and leveraging batch auctions, so trade order becomes irrelevant.
-Keep your surplus, If a price moves in your favour after you've placed an order, CoW Protocol gives you the price at the time of execution.
-Never pay for failed transactions. CoW Protocol never charges for failed transactions – unlike almost every DEXes or aggregator.
-ETH-less trading, CoW Protocol takes its fees in the sell token, so you can save your precious ETH.
-Execute many orders at once. Never wait for one trade to finish before placing another.
I believe that integrating CoW Protocol with Phantom's existing infrastructure would create great synergies in mitigating MEV.
