WallStreetTradersFeeHook

RobinhoodRegistered

Volatility-based fee hook for native ETH/token pools, charging 1–7% fees in ETH on each swap. Buy fees are taken from the ETH input in beforeSwap; sell fees from the ETH output in afterSwap. The fee rate scales with the previous swap's tick movement (realized volatility). Pool initialization is restricted to a whitelisted factory address; 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.
