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. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo PhiEthHooksImplements a 1:1 custom swap curve for ETH↔phiEth (a wrapped ETH token), bypassing concentrated liquidity by taking the full input, converting via phiEth.deposit()/withdraw(), and settling with a BeforeSwapDelta. Liquidity addition to the pool is permanently blocked. Base beforeInitbeforeAddLiqbeforeSwapswapDelta 1 12mo EulerSwapA custom-curve AMM hook backed by Euler Finance lending vaults. 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.

Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA Uniswap v4 hook implementing a custom AMM curve backed by Euler Finance lending vaults. In beforeSwap, the hook takes full control of swap accounting: input tokens are deposited into an Euler vault and output tokens are withdrawn from another, with the curve invariant verified before returning a BeforeSwapDelta to the pool manager. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 12mo EulerSwapA custom-curve Uniswap v4 hook that implements a single-LP AMM backed by Euler lending vaults.

Base beforeInit 1 12mo Asterix HookA fee-collection hook that takes a configurable percentage of each swap's unspecified output token: for native ETH outputs the fee is forwarded to a treasury, while for ERC-20 outputs it is burned by sending to a dead address. A separate configurable portion is always forwarded to a main treasury. Ethereum afterSwapafterSwapDelta 1 12mo STRMOGHookAccrues a 10% fee on all swaps in a designated ETH/STRMOG pool, routing collected fees to an immutable treasury address.
