EulerSwap

UnichainRegistered

A Uniswap v4 hook that implements a custom AMM backed by Euler Finance vaults. Swaps are fully intercepted in beforeSwap: input tokens are deposited into an Euler vault, output tokens are withdrawn from another vault, and all trades are validated against a custom bonding curve (CurveLib). Concentrated liquidity and donations are disabled to prevent idle or irrecoverable funds.

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.
