EulerSwap
UnichainRegisteredCustom-curve AMM hook backed by Euler vaults. Intercepts every swap in beforeSwap, computes quotes via its own bonding curve (CurveLib), deposits input tokens into an Euler vault and withdraws output tokens from another, then returns a BeforeSwapDelta to bypass Uniswap v4's standard CLAMM pricing. Verifies the curve invariant after each trade. Standard liquidity provision is blocked; only the hook's Euler-vault reserves participate in swaps.
What it can do
Its code executes inside each trade in pools that use it.
It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
It checks every deposit before it goes in.
It runs when a pool is created, often to lock in that pool’s settings.
It runs when someone donates tokens to the pool’s LPs.
