The PoolThe Pool protocol's volatility-adjusted fee hook (on-chain contract: DynamicFeeHookV2). Takes a percentage of each swap's output via afterSwapReturnsDelta (25 bps base, scaling up to 37.5 bps under realized volatility) and routes it to a fee distributor. Also supports reserve-sale fills in beforeSwap, where a registered vault can offer single-sided inventory to swappers at a chosen price in either price-improvement or vault-spread mode.
