FoxyFeeHook

RobinhoodRegistered

Volatility-adaptive ETH fee hook for FoxyLaunch pools that charges fees in native ETH on buys (via beforeSwap delta) and sells (via afterSwap delta), scaling between configurable base and max fee rates (1%–7%) based on the previous swap's tick movement. Only the bound factory may open pools on this hook; 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.

Runs at pool creation

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