Warning signal

tx.origin Check

The contract branches on tx.origin, often to gate trading to specific callers.

Analyzer: Source-Code Analysis
Slug: tx_origin_check

What it means

Reading tx.origin (the externally-owned account that started the call chain) inside trading logic is used to distinguish routers, bots and simulators from real users - and to let only some of them through. It is both an anti-bot and an anti-simulation pattern.

Why it matters

tx.origin checks are how a contract can let the deployer and whitelisted bots trade while quietly blocking everyone else, or behave for a checker and trap a human. It is rarely benign in a fresh token.

How RektRadar detects it

RektRadar flags tx.origin reads found in the verified source's transfer or trading functions.
