 2. [Sign](#sign) - Cryptographically sign the transaction locally and save the [transaction ID](#transaction-id). Signing is how the owner of an account authorizes a transaction to take place. For multisignature transactions, the `signedTransaction` fields returned by `sign` must be collected and passed to the [combine](#combine) method.
 3. [Submit](#submit) - Submit the transaction to the connected server.
 4. Verify - Verify that the transaction got validated by querying with [getTransaction](#gettransaction). This is necessary because transactions may fail even if they were successfully submitted.
