Warning signal

gasleft() Anti-Simulation Check

The contract inspects remaining gas, a trick to behave differently under simulation.

Analyzer: Source-Code Analysis
Slug: gasleft_check

What it means

A call to gasleft() inside transfer or trading logic lets a contract tell whether it is running in a real transaction or a checker's simulation, since the two leave different gas profiles. It is a known anti-honeypot-checker tell.

Why it matters

There is no legitimate reason for a memecoin to branch on remaining gas during a transfer. When it does, it is usually deciding whether to spring the trap - and your clean simulation may be exactly what it wanted you to see.

How RektRadar detects it

RektRadar scans the verified source for gasleft() usage inside transfer-path functions and raises this flag when found.
