Warning signal

Upgradeable Proxy

The contract is a proxy — its logic can be swapped without users' consent.

Analyzer: Source-Code Analysis
Slug: proxy_detected

What it means

A delegatecall-based proxy points to an implementation address that the admin can change. Yesterday's audited code can become tomorrow's malicious code with one transaction.

Why it matters

Most proxy rugs swap the implementation to one that allows the admin to drain everyone. The change is invisible on the proxy address — explorers show the same contract.

How RektRadar detects it

EIP-1967 storage slot read + bytecode signature match for transparent / UUPS / beacon proxies.

Blacklist Mapping — The contract can blacklist any address from selling — a kill-list with no notice period. Owner Not Renounced — The contract still has an owner — nothing prevents a future privileged change. Proxy Admin Role — An admin role exists and can change the proxy's implementation contract. Beacon Proxy — Multiple contracts share a single upgradeable implementation — one switch rugs all of them. UUPS Proxy — The implementation contract holds its own upgrade logic — accidental brick risk plus rug risk.
