Overview
Transaction simulation previews a transaction’s outcome before signing to avoid malicious effects. It helps users avoid scams and verify results. Tools like Tenderly and wallet simulators provide it.
How It Works
The transaction is executed in a simulated environment against current state, showing its effects without spending funds. Users review the result before approving. This reveals malicious behavior.
Why It Matters
Simulation prevents blind signing and reduces phishing and drain attacks. It is a powerful safety tool. It is increasingly built into wallets.
