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