UniHooks

EulerSwap

UnichainRegistered

A custom curve AMM hook for Uniswap v4 that implements a two-asset market maker backed by Euler lending vaults. Swaps are routed through a parametric curve; input assets are deposited to and output assets are withdrawn from Euler vaults. Concentrated liquidity and donations are intentionally blocked. Each deployed instance is a MetaProxy with pool parameters embedded in trailing calldata.

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.

Automated checks, not an audit
✓Not upgradeableNo proxy pattern found: the code is fixed.
✓No owner foundNo owner() function: nobody has an admin switch (as far as the standard check goes).
✓Listed in Uniswap’s hook registryRegistered with Uniswap Labs (a listing, not a security review).
✓Source code publishedThe code on the block explorer matches what's deployed (contract: EulerSwap).
iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
