const bch = require('bitcoincashjs')

const buf = new Buffer('__your_64_bit_private_key__', 'hex')
const privateKey = new bch.PrivateKey(buf, 'testnet')
const address = privateKey.toAddress('testnet')

insight.getUnspentUtxos(address.toString(), function (error, utxos) {
  if error {
    console.error(error)
    return
  }
  
  const utxo = {
    txid: utxos[0].txid,
    outputIndex: utxos[0].vout,
