ShiftyFeeHook

RobinhoodRegistered

Volatility-adjusted fee hook for ETH/token pools that charges 1–7% ETH fees on buys (beforeSwap) and sells (afterSwap), scaling with the previous swap's tick movement; fees are pushed directly to a per-pool fee recipient with no claim step. Only exact-input swaps are supported; exact-output swaps revert.

What it can do

Runs on every swap

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

Can change what you receive

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

Checks new pools

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