EulerSwap

ArbitrumRegistered

A custom-curve AMM hook backed by Euler lending vaults. In beforeSwap, it computes quotes against the EulerSwap curve, takes input tokens into the vault, withdraws output tokens from the vault, and returns a BeforeSwapDelta to fully handle swap accounting — bypassing Uniswap v4's internal liquidity. Swaps are blocked after a configurable expiration timestamp.

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.
