V4TaxHook

EthereumRegistered

Collects a fixed 5% tax (500 BPS) on buy and sell swaps of registered token pools. In beforeSwap, tax is deducted from the exact-input base-asset amount; in afterSwap, from the unspecified base-asset output. Taxes are minted as ERC-6909 claims to the token contract and recorded via ITaxedDividendToken for dividend distribution.

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.
