16mo EulerSwapA Uniswap v4 hook that implements a custom AMM backed by Euler lending vaults. On each swap, it takes the input token from the pool manager, deposits it into an Euler vault, withdraws the output token from a paired vault, and enforces a custom bonding curve (CurveLib) on the resulting reserves.
