What does transaction simulation do?

It replays your transaction against the current blockchain state without broadcasting it. You see exactly what assets would change hands, what approvals would be granted, and whether the transaction would succeed or revert — all before spending any gas.

Is it safe to simulate a transaction?

Yes. Simulation never submits anything to the blockchain. No gas is used and no state is changed. Your wallet and funds are completely unaffected.

What does 'High Risk' mean in simulation results?

It means the simulated transaction exhibits patterns associated with scams or malicious contracts — such as unlimited token approvals to unknown spenders, honeypot mechanics, or suspicious asset drains. You should not proceed with the real transaction.

Which chains are supported?

EVM-compatible chains: Ethereum, Base, Arbitrum, Optimism, Polygon, and BNB Chain.
