Create bitcoin transaction from BIP38 private key

create-bitcoin-tx.js

const { Transaction } = require('bitcore-lib')
const { decrypt } = require('bip38')

const encryptedKey = '<private key beginning with 6>'
const password = '<private key password>'

const privateKey = decrypt(encryptedKey, password).privateKey

// Check UTXO info at https://insight.bitpay.com/api/addr/<origin address>/utxo
const utxo = {
  'txid': '<txid>',
  'vout': <vout>,
  'scriptPubKey': '<scriptPubKey>',
  'satoshis': <satoshis>,
}

const tx = new Transaction()
tx.from(utxo)
tx.to('<to address>', <amount in satoshis>)
tx.fee(30000) // for ~258 bytes
tx.change('<back to origin address?>')
tx.sign(privateKey)

console.log(tx.toString())
