16mo EulerSwapA Uniswap v4 hook implementing a custom AMM backed by Euler Finance vault positions. Swaps are fully processed in beforeSwap: input tokens are deposited into an Euler vault, output tokens are withdrawn, and a bonding curve invariant is verified against updated reserves. Native concentrated liquidity is blocked; the hook acts as the sole liquidity source.
