HOODDOGFeeHook

RobinhoodRegistered

A volatility-based fee hook that charges ETH fees (1–5%) on swaps, scaling the fee by the previous swap's tick movement. Fees are collected via delta returns in beforeSwap (buys, zeroForOne exact-input) and afterSwap (sells), then forwarded directly to a per-pool fee recipient via poolManager.take().

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.
