api.connect().then(() => {

    "TransactionType": "Payment",
    "Account": sender,
    "Amount": api.xrpToDrops(amount),
    "Destination": destination,
  }, {
    // Expire this transaction if it doesn't execute within ~5 minutes:
    "maxLedgerVersionOffset": 75
  })
  const maxLedgerVersion = preparedTx.instructions.maxLedgerVersion
  return preparedTx.txJSON
}).then(txJSON => {
  const response = api.sign(txJSON, secret)
  const txID = response.id
  const txBlob = response.signedTransaction
  return txBlob;
}).then(txBlob => {
  const latestLedgerVersion = await api.getLedgerVersion()
  const result = await api.submit(txBlob)
  return latestLedgerVersion + 1
}).then((earliestLedgerVersion) => {
  return api.disconnect();
}).then(() => {
  process.exit();
}).catch(console.error);
