YardFeeHook

RobinhoodRegistered

Volatility-based fee hook for YardLaunch pools that charges ETH fees on buys (via beforeSwap delta) and sells (via afterSwap delta). The fee rate scales dynamically between a configurable base and max rate (1%–5.12%) based on the previous swap's tick movement, with only exact-input swaps 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.
