PairV5LaunchV2Hook

RobinhoodRegistered

A Uniswap v4 hook that collects a 70 bps fee on quote-token swaps via BeforeSwapDelta and afterSwapReturnDelta, routing collected fees to a per-pool vault. Maintains an on-chain TWAP oracle using a circular observation buffer (up to 32 entries) to support buyback price quoting.
