VolatilityFeeHook

RobinhoodRegistered

Charges a realized-volatility fee on every swap in the pool's quote currency. The fee rate ranges linearly from a base to a maximum (1%–5.3%) based on how far the previous swap moved the price (tick delta). Fees are collected as ERC-6909 claims on the PoolManager and forwarded to an immutable fee wallet via a permissionless sweep function. Exact-output swaps are rejected.

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.
