L2 Contracts Overview

The Angstrom L2 deployment consists of just two contracts:

• AngstromL2 – A Uniswap v4 hook that taxes swaps and JIT liquidity based on the sequencer priority fee, then redistributes the proceeds to pool creators, the protocol treasury, and LPs.
• AngstromL2Factory – A governance contract that deploys verified hooks, configures protocol fees, and exposes emergency controls.

These contracts implement the MEV-taxing model described in Priority is All You Need. There is no off-chain coordination layer—routers interact with the standard Uniswap v4 pool manager, and the hook’s callbacks handle the rest.
