Is this transaction safe to sign? Simulate an unsigned Base transaction against current chain state and get one verdict back: what the call does, the gas it burns, which balances and allowances move, and whether it hides an unlimited approval or a target that changed under you. Returns allow, review or block with reason codes, evidence and the block it stops being valid. Never cached, shared or resold: your unsigned transaction stays private to the wallet that paid for it.
