Warning signal

Possible Simulation Detection

The contract reads block/miner fields that scams use to behave differently inside a simulator.

Analyzer: Composite Verdicts
Slug: possible_simulation_detection

What it means

Some honeypots detect when they are being dry-run by a checker and behave nicely, then turn malicious for real buyers. Reading tx.gasprice, block.coinbase or gasleft() inside transfer logic is a common tell of this anti-simulation trick - especially in an unverified contract.

Why it matters

Anti-simulation logic is built for one reason: to pass automated honeypot checks while still trapping humans. If a contract is engineered to detect simulators, the clean result you got cannot be trusted.

How RektRadar detects it

RektRadar flags this when simulation-sensitive opcodes (gasprice or coinbase) appear in a contract whose source is unverified, combining the bytecode read with the verification status into one composite signal.
