FarmIndexFeeHook

RobinhoodRegistered

Volatility-based dynamic fee hook for ETH/token pairs launched via FarmIndexLauncher. Charges ETH fees on swap input for buys (beforeSwap) and on ETH output for sells (afterSwap), with the fee rate scaling between a configured base and max BPS based on the previous swap's tick movement. Fees are sent directly to the pool's fee recipient on every swap.

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.
