Paradigm General Partner and Head of Research Dan Robinson and Research Partner Dave White published an article introducing the MEV tax, which will allow any application to capture its MEV and retain composability.
This mechanism is now available on OP Stack L2s such as OP Mainnet, Base, and Blast, because the block proposers on these chains follow the rules of "competitive priority sorting".
The two said that the MEV tax is a simple technology that can be thought of as allowing any application on the chain to run its own custom MEV auction without any of its own off-chain infrastructure, just connecting to a single shared auction run by the block proposer; L2 is encouraged to consider using priority sorting (OP Stack supports it by default), and applications are encouraged to try MEV taxes if they support it.
