Charges different fees based on whether a swap adds or removes a designated target asset, incorporating keeper-supplied volatility and inventory skew data that must be refreshed every 30 minutes.

Fees are forwarded to an owner-configured FeeDistributor. Uses per-pool, block-gated price tracking to prevent cross-pool oracle manipulation. Arbitrum beforeSwapafterSwapafterSwapDelta 1 6mo 0x0000…0020Handles donations to LPs Arbitrum beforeDonate 1 6mo The PoolUniswap v4 dynamic fee hook that captures 25 bps per swap (scaling 1.5× in volatile blocks) and routes 80% of fees back to in-range LPs via poolManager.donate(), with the remaining 20% to treasury. Pairs with an ERC-4626 vault for auto-compounding LP yield. No emissions token.

Users configure grid parameters and deploy orders; the hook tracks swaps for MEV protection and enforces a per-block maximum tick movement limit, reverting swaps that would cause excessive price impact.

Swaps are executed entirely in beforeSwap by taking input tokens into an Euler vault and withdrawing output tokens from another, using a configurable curve invariant with optional expiration. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 7mo ClassicSwapHookA Uniswap v4 hook that wraps a single pool with V2-style full-range liquidity, issuing fungible ERC-20 LP tokens proportional to deposited amounts. Direct liquidity modification is blocked at the hook level; all deposits and withdrawals go through the hook's own deposit/withdraw functions. Arbitrum afterInitbeforeAddLiqbeforeRemoveLiq 1 7mo EulerSwapCustom-curve AMM hook that routes swaps through Euler lending vaults (EVC). Handles the full swap execution in beforeSwap: computes quotes against vault reserves, deposits input tokens into Euler supply vaults, and withdraws output tokens — bypassing standard Uniswap v4 pool liquidity. Blocks external LP positions, donations, and supports optional pool expiration via block.timestamp.
