Warning signal

Upgradeable Proxy

The contract can delegate or upgrade its logic (delegatecall / upgradeTo).

Analyzer: Source-Code Analysis
Slug: upgradeable_proxy

What it means

The source uses delegatecall or exposes upgradeTo/upgradeToAndCall. The code you audited today is not necessarily the code that runs tomorrow.

Why it matters

Upgradeability without a timelock means every guarantee is revocable: clean transfer logic can be swapped for a honeypot after liquidity arrives. Sibling signals proxy_detected/uups_proxy/beacon_proxy cover the bytecode side.
