HookeFeeHook

RobinhoodRegistered

A protocol-fee hook for a single hXMAX/USDG pool that charges a 2%–4% USDG-only fee per swap based on the pool price's deviation from an oracle price. Fees on the specified stablecoin leg are pre-taken in beforeSwap via BeforeSwapDelta; fees on the unspecified leg are taken in afterSwap via AfterSwapReturnsDelta. Also records tick-cumulative observations to serve a TWAP via consultMeanTick.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
