MoonsendFeeHook_WETH

EthereumRegistered

Uniswap v4 hook that gates pool initialization to factory-pre-registered pools and sets an immutable per-pool dynamic LP fee (from a fixed allowlist of five tiers) via updateDynamicLPFee() in afterInitialize. Has no swap callbacks — the fee is written once at pool creation and cannot be changed afterwards.
