// 從 Alice 提交一個交易給另一用戶
const unsub = await api.tx.balances
  .transfer(recipient, 12345)
  .signAndSend(alice, ({ eventRecords = [], status }) => {
    console.log(`Current status is ${status.type}`);

    if (status.isInBlock) {
      console.log(`Transaction included at blockHash ${status.asInBlock}`);
    } else if (status.isFinalized) {
      console.log(`Transaction finalized at blockHash ${status.asFinalized}`);
      unsub();
