HatTrickHook

EthereumRegistered

Uniswap v4 afterSwap hook for a $HAT/WETH pool that captures a configurable BPS fee on each swap via afterSwapReturnsDelta, then splits it three ways: to a prize vault, burned (directly for HAT fees or deferred via buybackAndBurn() for WETH fees), and to a treasury address. Fee rate and split ratios are owner-configurable within set bounds.

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.
