BaseEthHook

EthereumRegistered

Charges a fixed 1% fee on both buy and sell swaps in a native ETH / ERC-20 token pool. In beforeSwap it returns a BeforeSwapDelta to retain the fee on exact-input ETH buys; in afterSwap it collects the fee via poolManager.take() and notifies the paired token contract via a safe callback.

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.
