HypzFeeHook

RobinhoodRegistered

Volatility-based dynamic fee hook for HypzLaunch ETH/token pools. Charges native ETH fees on buys (from input in beforeSwap) and sells (from ETH output in afterSwap), with the rate scaling between a configurable base and max (both in 1%–6.6%) based on the tick movement of the previous swap. Only exact-input swaps are accepted.

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.
