EulerSwap

UnichainRegistered

A custom-curve AMM hook for Uniswap v4 that implements concentrated liquidity backed by Euler lending vaults. All swap logic runs in beforeSwap: input tokens are deposited into an Euler vault, output tokens are withdrawn, and a BeforeSwapDelta is returned to bypass standard pool accounting. Each pool instance is deployed as a delegatecall proxy of a shared EulerSwap implementation.

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.
