EulerSwapEulerSwap is a Uniswap v4 hook implementing a custom AMM curve backed by Euler lending vaults. Swaps are fully handled in beforeSwap: input tokens are deposited to and output tokens withdrawn from Euler vaults, with amounts determined by a custom pricing curve that verifies a reserve invariant.

EulerSwapA custom-curve AMM hook backed by Euler Finance vaults. In beforeSwap, it computes a quote via a custom bonding curve (CurveLib), deposits input tokens into an Euler vault, withdraws output tokens from another vault, and returns a BeforeSwapDelta to settle balances directly—bypassing standard concentrated liquidity. beforeAddLiquidity and beforeDonate always revert to prevent non-productive positions.
