However, it will not have the associated state\nhashes, as they are not updated in storage.  This can be used to estimate the maximum gas\nunits for a submitted transaction.\n\nTo use this, you must:\n- Create a SignedTransaction with a zero-padded signature.\n- Submit a SubmitTransactionRequest containing a UserTransactionRequest containing that signature.\n\nTo use this endpoint with BCS, you must submit a SignedTransaction\nencoded as BCS.
