EulerSwap

UnichainRegistered

EulerSwap is a Uniswap v4 hook that implements a custom AMM backed by Euler Protocol vaults. All swap logic executes in beforeSwap using a custom concentrated liquidity curve, depositing input tokens into and withdrawing output tokens from Euler vaults. It blocks standard liquidity additions, donations, and unauthorized pool initializations to enforce its custom curve invariant.

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.
