EulerSwap

UnichainRegistered

EulerSwap is a Uniswap v4 hook implementing a custom AMM curve using Euler vault-backed liquidity. Swaps execute entirely within `beforeSwap`: input tokens are deposited into Euler vaults, output tokens withdrawn, and a custom curve invariant verified — bypassing Uniswap's CLAMM via `beforeSwapReturnsDelta`. Standard liquidity positions and donations are intentionally blocked.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.

Handles donations to LPs

It runs when someone donates tokens to the pool’s LPs.
