Create new transaction

var faucet = require('helloblock-faucet')
var bitcoin = require('bitcoinjs-lib')
var request = require('request')

faucet.getUnspents(1, function (error, data) {
  if (error !== null) {
    return console.log(error)
  }

  var privKey = bitcoin.ECKey.fromWIF(data.privateKeyWIF)
  var total = 0
  var txb = new bitcoin.TransactionBuilder()
  data.unspents.forEach(function (unspent) {
    total += unspent.value
    txb.addInput(unspent.txHash, unspent.index)
  })
  txb.addOutput('testnet_address', total - 10000)
  data.unspents.forEach(function (_, index) {
