EulerSwap

UnichainRegistered

A custom AMM hook that replaces Uniswap v4's concentrated liquidity with a bonding-curve swap mechanism backed by Euler vaults. In beforeSwap, it computes quotes via a custom curve library, deposits input tokens into an Euler vault, and withdraws output tokens from another Euler vault, returning a BeforeSwapDelta to fully handle swap accounting.

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.
