ToyhoodFeeHook

RobinhoodRegistered

Volatility-based dynamic fee hook for ETH/token pools launched by ToyhoodLauncher. Charges ETH fees on buys (taken from input in beforeSwap) and sells (taken from output in afterSwap), with the fee rate scaling between configurable base and max bands (1%–6.2%) based on the tick movement of the previous swap.

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.
