EulerSwap

UnichainRegistered

A custom AMM hook backed by Euler Finance vaults that fully replaces standard Uniswap v4 swap execution. In beforeSwap, it computes amounts via a custom two-asset concentrated liquidity curve, takes input tokens from the PoolManager into an Euler vault, withdraws output tokens from another Euler vault, and enforces the curve invariant on updated reserves.

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.
