aa simulate
Validates a UserOperation structurally and against chain state. It computes the required prefund from the gas limits and fee fields, reads the sender deposit on the EntryPoint and, when a paymaster is set, that paymaster deposit and stake, and says plainly whether the operation is funded. The nonce is read from the EntryPoint and compared with the one supplied, so a stale nonce is caught before submission.
