UniV4Hook

EthereumRegistered

A dynamic-fee hook that charges a size-proportional LP fee (scaling with swap size relative to virtual reserves) to protect LPs from impermanent loss, with a configurable base fee (default 0.3%) plus add-on. Restricts liquidity to an owner-managed allowlist via stake()/unstake(), enforcing full-range positions only. Registered owner2Executors can bypass the size-based fee and trade at 0%.
