16mo EulerSwapA custom curve AMM hook for Uniswap v4 that implements a two-asset market maker backed by Euler lending vaults. Swaps are routed through a parametric curve; input assets are deposited to and output assets are withdrawn from Euler vaults. Concentrated liquidity and donations are intentionally blocked. Each deployed instance is a MetaProxy with pool parameters embedded in trailing calldata.
