UnichainRegistered

EulerSwap is a Uniswap v4 hook on Unichain. A custom-curve Uniswap v4 hook backed by Euler Finance lending vaults.

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.

Safety report

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).

!In Uniswap’s hook registry, not tradeable in Uniswap’s app yetRegistered with Uniswap Labs (a listing, not a security review). It runs code on swaps, so Uniswap’s app only routes it once Uniswap Labs approves it, and it isn’t approved yet. Adding liquidity still works, and other apps can trade it.

✓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.

?No audit linkedAutomated checks only.
