Warning signal

Blacklist Function

The contract ships a function to ban specific addresses from trading.

Analyzer: Source-Code Analysis
Slug: blacklist_function

What it means

The source declares a blacklist/addBlacklist/setBlacklist/ban style function. The operator can selectively prevent chosen addresses from transferring - typically right after they buy.

Why it matters

Selective blacklisting is the targeted honeypot: the token trades normally for everyone else, so charts and honeypot checkers look clean, while blacklisted buyers are silently trapped.

How RektRadar detects it

Source regex on blacklist/ban setter signatures. Complementary signals: blacklist_mapping (the storage), blacklist_detected (live simulation hit), hardcoded_address_blacklist (addresses baked in code).
