Warning signal

Beacon Proxy

Multiple contracts share a single upgradeable implementation - one switch rugs all of them.

Analyzer: Source-Code Analysis
Slug: beacon_proxy

What it means

A beacon proxy reads its implementation from a shared `Beacon` contract. Many tokens can be deployed against the same beacon, and one upgrade affects every dependent contract simultaneously.

Why it matters

Beacons are a rug force-multiplier. The operator deploys 50 tokens against one beacon, builds liquidity over weeks, then upgrades the beacon to a malicious implementation, draining all 50 at once.

How RektRadar detects it

Bytecode signature for `BeaconProxy` (`getImplementation()` via beacon) plus storage slot inspection.

Detected on 6 tokens in our dataset so far, 6 classified scam. Sample still small - a reliable scam rate needs more occurrences.

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. Upgradeable Proxy - The contract is a proxy - its logic can be swapped without users' consent. Proxy Admin Role - An admin role exists and can change the proxy's implementation contract. UUPS Proxy - The implementation contract holds its own upgrade logic - accidental brick risk plus rug risk.
