Periodically harvests LP fees from a HORN/UNI pool to burn HORN and distribute UNI to holders proportionally; includes a "monarch" mechanic where the highest horn-length holder can claim a crown pot after a cooldown.

A pre-authorized filler later settles by delivering at least the maker's specified minimum output. Supports order cancellation and limit-price updates; full-fill only in v1. Unichain beforeInitbeforeAddLiqbeforeSwapswapDelta 1 6mo AsyncSwapAsync order book that intercepts exact-input swaps — the maker's input is taken as a 6909 claim and an open order is created at a limit price. A filler later settles by delivering the minimum output amount directly to the maker, bypassing the AMM entirely. Unichain beforeInitbeforeAddLiqbeforeSwapswapDelta 1 6mo 0x14aa…e080Runs code on every swap · Runs at pool creation Unichain beforeInitbeforeSwap 1 6mo CounterA simple counter hook that increments per-pool counters on beforeSwap, afterSwap, beforeAddLiquidity, and beforeRemoveLiquidity. Each callback only records call counts with no access control, fee logic, or swap modification. Unichain beforeAddLiqbeforeRemoveLiqbeforeSwapafterSwap 1 6mo PointsHookAwards ERC20 loyalty points to users who buy a paired token using TOKEN_A through allowlisted routers. In afterSwap, mints points proportional to the TOKEN_A amount spent; non-allowlisted routers can still swap but receive no points.

It tracks directional market imbalance across swaps and charges higher fees when swaps increase imbalance, using a configurable illiquidity metric and min/max fee bounds.

Rewards are distributed to in-range liquidity providers using ERC-6909 accounting and tick-based reward growth tracking, with claims settled through PositionManager NFT ownership. Unichain beforeAddLiqafterAddLiqbeforeRemoveLiqafterRemoveLiq+3 1 8mo DynamicFeeHookAdjusts LP swap fees dynamically based on on-chain price volatility using EWMA of sqrt price changes; collects a configurable owner-controlled protocol fee share from the spread above the base fee into a treasury address. In practice, the afterInitialize flag is absent from the address bitmask, so pool configs are never populated and the hook always returns a hardcoded 3000 bps fallback fee.

Unichain afterInitbeforeSwapafterSwapafterSwapDelta 1 9mo VolatilityDynamicFeeLimitOrderHookA Unilaunch singleton hook that adjusts LP fees dynamically based on a volatility oracle with configurable surge multipliers (activated during high-volatility periods), enforces a one-block trading delay on pool launch, and triggers limit order execution via ILimitOrderManager on every swap. Unichain beforeInitbeforeSwapafterSwap 1 9mo VolatilityDynamicFeeLimitOrderHookUnilaunch singleton hook that implements volatility-responsive dynamic LP fees: applies a base fee plus a surge multiplier when large tick movements are detected in afterSwap, decaying it over a configurable duration. Blocks trading for one block after pool initialization as an anti-sandwich measure. Integrates with an external limit order manager for limit order execution. Unichain beforeInitbeforeSwapafterSwap 1 9mo VolatilityDynamicFeeLimitOrderHookSingleton hook for Unilaunch pools that dynamically adjusts LP fees based on volatility, applying surge fee multipliers after high-volatility CAP events detected by an on-chain oracle. Executes limit orders via an external LimitOrderManager after each swap, and gates trading until a configured block number. Unichain beforeInitbeforeSwapafterSwap 1 9mo VolatilityDynamicFeeLimitOrderHookRuns code on every swap · Sets its own swap fee · Runs at pool creation Unichain beforeInitbeforeSwapafterSwap 1 9mo VolatilityDynamicFeeLimitOrderHookAdjusts LP fees dynamically based on a configurable base fee plus a time-decaying surge fee triggered by volatility cap events detected via a VolatilityOracle. Also executes on-chain limit orders through a LimitOrderManager on each swap, and temporarily blocks trading until a configured block number to prevent launch sniping.
