The hook returns a BeforeSwapDelta to override pool accounting, deposits input tokens into Euler vaults, and withdraws output tokens from Euler vaults. Each hook instance is a minimal proxy delegating to a shared EulerSwap implementation; native CLMM liquidity and direct pool initialization are blocked. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 15mo EulerSwapA custom AMM hook for Euler Finance that handles full swap execution via beforeSwap: it computes amounts using a concentration-based price curve, deposits input tokens into Euler lending vaults, withdraws output tokens from Euler vaults, and returns a BeforeSwapDelta so the pool manager performs no additional swap math. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 15mo EulerSwapA custom curve AMM hook backed by Euler Finance vaults. Swaps are handled entirely in beforeSwap using a custom bonding curve, with input tokens deposited into and output tokens withdrawn from Euler vaults; beforeSwapReturnsDelta bypasses standard Uniswap v4 pool accounting. Prevents standard liquidity additions, donations, and external pool initialization. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 15mo EulerSwapA Uniswap v4 hook implementing a custom AMM using a bonding curve backed by Euler lending vaults. Replaces standard concentrated liquidity: beforeSwap handles the entire swap by depositing input tokens into an Euler vault and withdrawing output tokens, then verifies a custom curve invariant, returning a full BeforeSwapDelta to the pool manager. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 15mo EulerSwapA custom-curve AMM hook that routes swaps through Euler Finance lending vaults. Each instance is a factory-deployed proxy managing a pair of Euler vaults; swaps are priced via a bespoke curve invariant and settled by depositing input tokens into and withdrawing output tokens from the corresponding vaults. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 15mo EulerSwapA custom-curve AMM hook for Uniswap v4 that routes swaps through Euler Finance lending vaults. It fully handles swap execution in beforeSwap via BeforeSwapDelta, implementing its own bonding curve invariant, and blocks native concentrated liquidity positions by reverting on beforeAddLiquidity and beforeDonate. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 15mo 0x15e2…5540Runs code on every swap · Runs at pool creation Arbitrum afterInitafterAddLiqafterRemoveLiqafterSwap 1 15mo DynamicFeeHookA Uniswap v4 hook that records the pre-swap tick in transient storage and calls a LimitOrderManager to execute limit orders triggered by tick crossings after each swap. The contract owner can also update the pool's LP fee dynamically via updateDynamicLPFee(). Arbitrum beforeSwapafterSwap 1 15mo LimitOrderHookRecords the pre-swap tick via transient storage in beforeSwap, then in afterSwap calls an external LimitOrderManager to execute any limit orders whose tick range was crossed during the swap. Arbitrum beforeSwapafterSwap 1 15mo EulerSwapCustom AMM hook backed by Euler Protocol vaults implementing a concentrated-style curve. On each swap, input tokens are deposited into an Euler vault and output tokens are withdrawn from another vault; the hook processes the full swap via beforeSwap return delta, bypassing Uniswap's CLAMM, and verifies the curve invariant after every trade. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 15mo EulerSwapEulerSwap is a custom-curve AMM hook that routes swaps through Euler Finance vault positions. Rather than using Uniswap v4 concentrated liquidity, it deposits input tokens into and withdraws output tokens from Euler vaults, enforcing a configurable bonding curve in beforeSwap with delta returns. Standard liquidity positions and donations are blocked.

Provides its own LP token (ERC-20) and manages reserves directly, replacing the standard concentrated liquidity curve. Arbitrum beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+2 1 15mo VTSwapHookA custom-curve AMM hook for swapping between a Vesting Token (VT) and its underlying Token (T). Implements reserve-based pricing via an external helper contract, issues ERC-20 LP tokens, and fully overrides Uniswap v4 swap execution via beforeSwapReturnsDelta.
