Safety report

Automated checks, not an audit

!Upgradeable proxyThe owner can replace the code (currently 0xaeae…4a2e). Rules can change after you trade.

✓No owner foundNo owner() function: nobody has an admin switch (as far as the standard check goes).

!Not in Uniswap’s hook registry, not tradeable in Uniswap’s app yetUnregistered hooks get less scrutiny. Most scam hooks are unregistered. 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 not checked yetThe block explorer didn’t answer in time. Reload in a moment.

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.
