Swaps are handled entirely in `beforeSwap` via delta returns: input tokens are deposited into an Euler vault and output tokens are withdrawn from another, with reserves verified against a configurable curve invariant (CurveLib). Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom AMM hook that routes Uniswap v4 swaps through Euler Finance vaults. The beforeSwap handler computes quotes using a proprietary curve invariant, deposits input tokens into and withdraws output tokens from Euler vaults, and returns a custom delta to the PoolManager — bypassing standard concentrated liquidity. Liquidity addition and donations are intentionally blocked. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapCustom-curve AMM hook backed by Euler lending vaults. Computes swap amounts via a configurable bonding curve, handles full settlement in beforeSwap by taking input tokens into Euler vaults and withdrawing output tokens from them, and returns a BeforeSwapDelta to the PoolManager — bypassing standard concentrated liquidity entirely. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA Uniswap v4 hook that implements a custom AMM curve backed by Euler Finance lending vaults.

Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom-curve Uniswap v4 hook backed by Euler lending vaults. In beforeSwap, it routes token flows through configurable Euler vaults, verifies a custom concentration curve, and returns a full BeforeSwapDelta to bypass standard concentrated liquidity mechanics — acting as a self-contained AMM that uses Euler vault balances as its liquidity source. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapEulerSwap is a custom-curve AMM hook backed by Euler Finance lending vaults. In beforeSwap it computes pricing via its own curve invariant, deposits swap input into an Euler vault, withdraws swap output from another Euler vault, and returns a BeforeSwapDelta to the PoolManager, bypassing Uniswap concentrated liquidity entirely. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA Uniswap v4 hook implementing a custom AMM curve backed by Euler Finance lending vaults. Each hook instance is a delegatecall proxy; swaps deposit input tokens into and withdraw output tokens from Euler vaults directly, enforcing a concentration-parameterized invariant curve rather than the standard xy=k formula. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom-curve AMM hook backed by Euler Finance vaults. In beforeSwap, it computes swap quotes using a proprietary bonding curve, deposits input tokens into Euler vaults, withdraws output tokens from Euler vaults, and returns the full swap delta to bypass Uniswap v4's standard pool math. Liquidity addition and donations are intentionally blocked via reverts. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapSingle-LP AMM hook implementing a custom bonding curve backed by Euler lending vaults. In beforeSwap, it computes quotes via its custom curve, deposits input tokens into an Euler vault, withdraws output tokens, and returns a BeforeSwapDelta to fully bypass Uniswap v4's CLAMM math. Prevents standard LP positions and donations via revert-only beforeAddLiquidity and beforeDonate. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA Uniswap v4 hook implementing a custom AMM that routes swaps through Euler Finance lending vaults. In beforeSwap, it takes input tokens into an Euler vault, withdraws output tokens from another vault, and enforces a custom curve invariant — fully replacing the standard pool swap logic via BeforeSwapDelta. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom-curve Uniswap v4 hook that routes swap assets through Euler Finance lending vaults and enforces a proprietary AMM curve invariant (EulerSwap v1). Intentionally reverts on direct liquidity additions and donations; swap accounting is handled entirely in beforeSwap via BeforeSwapDelta.

In beforeSwap, it fully handles each swap by taking input tokens from the pool manager, depositing them into an Euler vault, withdrawing output tokens from another vault, and verifying a proprietary curve invariant — bypassing standard Uniswap v4 concentrated liquidity entirely. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom-curve AMM hook for Uniswap v4 that routes swaps through Euler Protocol lending vaults. In beforeSwap, it computes quotes using a bonding-curve invariant, deposits input tokens into an Euler vault, withdraws output tokens from the opposite vault, and returns a BeforeSwapDelta to handle all pool accounting. Vanilla concentrated-liquidity positions are blocked. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapCustom AMM hook for Uniswap v4 that implements a proprietary pricing curve backed by Euler Finance vaults. On each swap, it deposits input tokens into and withdraws output tokens from Euler vaults via EVC accounts, bypassing standard Uniswap concentrated liquidity. Each pool instance is deployed as a minimal delegatecall proxy to this implementation contract. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom curve AMM hook that routes swaps through Euler Finance lending vaults rather than Uniswap v4 concentrated liquidity pools. In beforeSwap, the hook computes quotes using its own curve invariant, takes input tokens into an Euler vault, and withdraws output tokens from a second vault, returning a BeforeSwapDelta to fully handle the swap accounting. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom-curve AMM hook that routes swaps through Euler lending vaults instead of concentrated liquidity. In beforeSwap, it deposits input tokens into an Euler vault and withdraws output tokens, enforcing a bonding-curve invariant. It blocks direct liquidity additions and donations to prevent misuse of the underlying Uniswap v4 pool. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapEulerSwap is a custom-curve AMM hook that routes swaps through Euler Finance lending vaults rather than Uniswap concentrated liquidity.
