ToyhoodFeeHook

RobinhoodRegistered

Volatility-based dynamic fee hook for ETH/token pools. Charges fees (1%–6.2%) on buys via beforeSwap delta (ETH input) and on sells via afterSwap delta (ETH output), with the fee scaling between a base and max rate based on tick movement from the previous swap. Fees are sent directly to a per-pool fee recipient; only exact-input swaps are permitted.

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.
