VolatilityFeeHook

RobinhoodRegistered

Charges a volatility-adjusted swap fee denominated in the pool's quote currency, scaling linearly between a base and max rate based on how far the previous swap moved the price (tick delta). Fees accumulate as ERC-6909 claims on the PoolManager and are forwarded to an immutable fee wallet via the permissionless `sweep()` function.

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.
