Supports role-gated dynamic LP fee updates via updateDynamicLPFee(). Arbitrum beforeSwapafterSwap 1 16mo LimitOrderHookA Uniswap v4 hook that enables on-chain limit orders by recording the current tick before each swap (via transient storage) and triggering execution of crossed limit orders through an external LimitOrderManager after each swap. A privileged fee manager role can update the pool's dynamic LP fee via poolManager.updateDynamicLPFee(). Arbitrum beforeSwapafterSwap 1 16mo LimitOrderHookA Uniswap v4 hook that records the current tick before each swap via transient storage, then triggers limit order execution in afterSwap based on tick movement. Includes a privileged role that can update the pool's dynamic LP fee via poolManager.updateDynamicLPFee().

The beforeSwap returns a hardcoded fee value (4000) without the OVERRIDE_FEE_FLAG set, so it has no effect on swap execution.

Requires pools to use dynamic fees and reverts any swap that would cause slippage exceeding 5%. Arbitrum afterInitbeforeSwap 1 19mo 0xa9db…c540Runs code on every swap Arbitrum afterAddLiqafterRemoveLiqafterSwap 1 19mo YieldSwapHookA custom AMM hook for Uniswap v4 that implements a time-decaying yield pricing curve for SY (Standardized Yield) and PT (Principal Token) pairs. Swap amounts are computed via a logarithmic formula whose rate scalar and anchor decay linearly from epoch start to zero at epoch end, with reserves managed internally by the hook. Arbitrum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+1 1 19mo 0xb974…c440Runs code on every swap Arbitrum afterAddLiqafterSwap 1 19mo YieldSwapHookA custom AMM hook for yield products (SY and PT tokens) that implements a time-weighted pricing formula using a logarithmic curve. Supports only unidirectional (SY→PT), exact-input swaps; price decays linearly from epoch start to end. Liquidity is managed via ERC-20 shares using a Uniswap V2-style formula. Arbitrum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+1 1 19mo YieldSwapHookCustom AMM hook for yield token pairs (SY and PT), implementing a time-weighted pricing formula with a decaying rate anchor (Pendle-style curve). Supports only exact-input SY-to-PT swaps; LP shares are issued as ERC20 tokens managed by the hook itself.

The swapper's address must be ABI-encoded in hookData; the pool owner manages the blacklist via setBlackListStatusForAddress. Swaps from unlisted addresses proceed normally.
