Priority is all you need

The article introduces MEV taxes, a mechanism that lets an application capture its own MEV by charging a fee that is a function of a transaction's priority fee. It says this could work today on OP Stack L2s such as OP Mainnet, Base and Blast, whose block proposers follow competitive priority ordering, and gives an example in which a tax of $99 for every $1 of priority fee captures 99% of the competitive MEV. The authors note that MEV taxes only work if block proposers strictly follow those ordering rules, so they currently depend on trusting L2 sequencers. The article also sketches uses for DEX routers such as UniswapX, AMMs, and wallets.
