Stores metadata for collectible ERC-20 tokens. Calls start on the configured token when first liquidity is added, and updates randomSeed on swaps. Ethereum afterAddLiqafterSwap 2 9mo EQTBuySellDynamicFeeHookApplies asymmetric LP fees on EQT/USDT pools — 1% when buying EQT and 4% when selling EQT — by returning an lpFeeOverride in beforeSwap. Reverts on any pool that is not the EQT/USDT pair or not configured as a dynamic fee pool. BNB beforeSwap 2 9mo VolatilityDynamicFeeLimitOrderHookUnilaunch singleton hook that applies volatility-based dynamic LP fees with surge pricing triggered by tick-change-per-block thresholds (CAPs), and executes limit orders after each swap. Trading is blocked for one block after pool registration via a block.number gate. Unichain beforeInitbeforeSwapafterSwap 2 9mo TradingFeeHookCollects a fixed 5% trading fee on swaps in registered pools, routing 0.5% to a treasury and 4.5% to token creators via a RevenueVault. Uses beforeSwap for exact-input buys and afterSwap for sells and exact-output buys, with WETH unwrapped to ETH before distribution.

The current fee is returned as an override in beforeSwap, with per-pool configurable min/max bounds and an owner-controlled updater allowlist. BNB beforeInitafterInitbeforeSwap 2 9mo 0xcebe…c040Runs code on every swap Ethereum afterSwap 2 9mo AquinasPoolHookA Uniswap v4 hook for Aquinas DAOs that gates pool initialization to factory-authorized addresses. The factory registers a Safe address as the authorized initializer for each pool; any other caller is reverted, preventing frontrunning of LP initialization. Has no swap-path logic.

In afterSwap, whitelisted bots can trigger JIT arbitrage via poolManager flash accounting (vacuum execution); non-whitelisted callers receive only fee gating.
