16mo EulerSwapEulerSwap is a custom-curve hook that uses Euler Finance vaults as liquidity sources. In beforeSwap, it deposits input tokens into an Euler vault, withdraws output tokens from another vault, and enforces a custom curve invariant (EulerSwap v1), returning a BeforeSwapDelta to bypass Uniswap's standard AMM pricing entirely. Standard add-liquidity, donations, and direct pool initialization are all reverted. Unichain beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 16mo EulerSwapA custom AMM hook for Uniswap v4 that implements a concentrated liquidity curve backed by Euler Finance vaults. Swaps are handled entirely in `beforeSwap` via `beforeSwapReturnsDelta`, depositing input assets into and withdrawing output assets from Euler vaults while verifying a custom curve invariant. Standard Uniswap v4 liquidity positions and donations are blocked; the hook serves as the sole liquidity source. Unichain beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 16mo EulerSwapA Uniswap v4 hook implementing a custom AMM curve backed by Euler Finance vaults.
