CardwallFeeHook

RobinhoodRegisteredLaunch a pool with this hook

Uniswap v4 hook for Cardwall token launches that charges ETH fees on swaps using a volatility-based dynamic rate (1%–7%). Buy fees are deducted from ETH input in beforeSwap; sell fees from ETH output in afterSwap. The fee scales linearly with the previous swap's tick movement and is sent immediately to the pool's configured fee recipient.

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.
