RichFeeHook

RobinhoodRegistered

Charges a volatility-based ETH fee on buys (beforeSwap delta) and sells (afterSwap delta), scaling the rate between a configurable base and max (both in the 1–5% range) based on the previous swap's tick movement. Fees are sent immediately to a per-pool recipient address set at registration.

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.
