DeployerTaxHook

EthereumRegistered

Charges a configurable buy/sell tax (up to a hardcapped 15%) on exact-input swaps for a single token pool by intercepting swaps via BeforeSwapDelta to reduce effective input. Fees accrue as ERC6909 claim tokens on the PoolManager and can be drained to a designated dev wallet by anyone calling drainFees().
