In this post, we introduce MEV taxes, a mechanism that arbitrary applications can use to capture their own MEV. This mechanism could be used today on OP Stack L2s like OP Mainnet, Base, and Blast, because the block proposers on those chains follow a set of rules we call competitive priority ordering. To implement a MEV tax on one of these chains, a smart contract charges a fee that is a function of the priority fee of the transaction. We show that if an application charges searchers a MEV tax of (say) $99 for every $1 of priority fee, it can capture 99% of the competitive MEV for that transaction. MEV taxes are a simple technique that opens up a vast design space. You can think of them as allowing any application on the chain to run its own custom MEV auction, without needing any offchain infrastructure of its own, just by hooking into a single shared auction run by the block proposer. We show how MEV taxes could be used to solve three major problems in MEV research: Decentralized exch
