How to create a raw Bitcoin Cash transaction using JavaScript

ライブラリのインストール

npm install bch-lib

ライブラリのインポート

var bchLib = require('@owstack/bch-lib')

秘密鍵の設定

var privateKey = new bchLib.PrivateKey('your private key here');

transactionのUTXOを設定

var utxo = {  "txId" : "f8a258720cb68be265baf6828612a401567f916ee50fc276d817f647e4bc1246", "vout" : 0, "address" : "158avSA4mpuCsKDn8ntCdf5XCrofvmy7M1", "scriptPubKey" : bchLib.Script.buildPublicKeyHashOut("158avSA4mpuCsKDn8ntCdf5XCrofvmy7M1").toString(),  "amount" : 0.0009887 };

transactionの生成

var transaction = new bchLib.Transaction()
  .from(utxo)
  .to('18dHsjN9ZZxt99cd8bFJ3r7ajWmidgJEQq', 20000)
  .fee(1000)
  .change('158avSA4mpuCsKDn8ntCdf5XCrofvmy7M1')
  .sign(privateKey);

サンプル

// using osx, install brew, npm and bch-lib
// brew install npm
// npm install bch-lib
// to run the script 'node raw.js'

var bchLib = require('@owstack/bch-lib')

// you can create a paper wallet from https://walletgenerator.net/?currency=BitcoinCash
// of course, you can also create a wallet here using bch-lib
var privateKey = new bchLib.PrivateKey('your private key here');

// notice that the unspent amount has to be exact or the transaction will fail with a the following error
// 16: mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false/empty top stack element) (code -26)"
var utxo = {
  "txId" : "f8a258720cb68be265baf6828612a401567f916ee50fc276d817f647e4bc1246",
  "vout" : 0,
  "address" : "158avSA4mpuCsKDn8ntCdf5XCrofvmy7M1",
  "scriptPubKey" : bchLib.Script.buildPublicKeyHashOut("158avSA4mpuCsKDn8ntCdf5XCrofvmy7M1").toString(),
  "amount" : 0.0009887
};

// notice that the change address is the same as the address in the utxo
var transaction = new bchLib.Transaction()
  .from(utxo)
  .to('18dHsjN9ZZxt99cd8bFJ3r7ajWmidgJEQq', 20000)
  .fee(1000)
  .change('158avSA4mpuCsKDn8ntCdf5XCrofvmy7M1')
  .sign(privateKey);

console.log(transaction.toString());
