Safety report

Automated checks, not an audit

!Upgradeable proxyThe owner can replace the code (currently 0x1166…0fc0). Rules can change after you trade.

!Has an adminowner() is 0xc5d3…d21d. That account can usually change fees, limits or allowlists after you trade.

!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 code publishedThe code on the block explorer matches what's deployed (contract: ERC1967Proxy).
