A privileged fee manager role can update the pool's dynamic LP fee via poolManager.updateDynamicLPFee(). Unichain beforeSwapafterSwap 2 17mo UniswapV4KEMHookA Uniswap v4 hook that gates each swap with an off-chain signed quote from a designated signer, enforcing max input amounts and exchange rates. In afterSwap, excess output above the signed rate is absorbed as 'eg tokens' minted to the hook and claimable by authorized accounts.

Base fee 0.01% inside a 35 bps deadband; swaps that correct the deviation pay base + 50% of the excess, capped at 0.5%; from 100 bps both directions pay. Falls back to the base fee if the feed is stale or fails. afterInitialize + beforeSwap only; no deltas, hookData, storage, admin or upgradeability. Unichain afterInitbeforeSwap 1 32d 0x4bd5…d0c8Runs code on every swap · Can take tokens from swaps · Runs at pool creation Unichain afterInitbeforeSwapafterSwapswapDelta 1 38d LimitOrderHookA Uniswap v4 Hook that enables on-chain limit orders on supported liquidity pools. Users can set a target price, and when the pool price reaches the specified price, the Hook automatically executes the order. This enables users to place limit orders directly on Uniswap v4.

Supports an optional self-compounding LP program with configurable fee splits for autocompound, burn, pot refuel, and custom recipient. Unichain beforeInitafterSwap 1 53d GlueHookA Uniswap v4 hook for static-fee pools that implements a reference-tick-gated buyback pump and LP fee auto-harvesting with auto-compounding. After each swap, it harvests accrued LP fees, executes a nested pump swap to buy the configured main token using pot secondary tokens, and distributes all proceeds in a single batched send phase. Unichain beforeInitafterSwap 1 56d UniFoxHookA hook that restricts pool initialization to a single pre-configured uFOX pool (beforeInitialize rejects all other keys), then in afterSwap mints an NFT fox to a caller-supplied recipient when the swap delivers at least minBuy uFOX and does not exceed the optional maxBuy cap.

Executes limit orders in afterSwap when the pool price crosses user-defined trigger thresholds, deducts a configurable execution fee (default 5 BPS), and represents each order as an ERC721 NFT. Unichain afterInitafterAddLiqbeforeSwapafterSwap+3 1 3mo flUSDCHooksA custom constant-sum hook implementing 1:1 swaps between USDC and flUSDC. In beforeSwap, the hook takes the full input, converts it via flUSDC deposit or withdraw, and settles the output back to the PoolManager. Direct liquidity provision is blocked. Unichain beforeInitbeforeAddLiqbeforeSwapswapDelta 1 3mo flETHHooksA custom-curve hook for ETH/flETH pools implementing a 1:1 constant-sum swap: it takes the full input from the PoolManager, converts it via flETH deposit/withdraw, and settles the output back — bypassing concentrated liquidity math entirely. Direct liquidity addition is blocked.
