14mo SimpHookA dynamic fee hook that computes LP fees using a VPIN-based model. It tracks order imbalance across fixed-size volume buckets and estimates price impact via an illiquidity measure, then sets a per-swap fee override in beforeSwap. afterSwap records actual price impact and updates volume trackers for subsequent fee calculations.

By running application-specific auctions, Angstrom internalizes MEV and redirects the extracted value back to users, preventing arbitrage losses and sandwich attacks while reducing trading fees and gas.
