Sterling Crispin 🕊️(@sterlingcrispin):I’m a little torn on this because the only reason why a v4 liquidity pool hook would be able to quote you at a 1% fee and fill you at 18% is if you submitted your transaction willing to accept 18% slippage. Why do we accept MEV and not this? It’s not that dissimilar and however complex all of the execution code is onchain and verifiable you could just do a better job verifying what users fill prices would be and pick the better route. It’s a failure of routers to pick a bad route not a failure of smart contracts for being aggressive.
