Implementasi
- Tuliskan script dibawah pada notepad (notepad++) lalu save sebagai file javascript (contoh : btc.js)
- Buka CMD dan arahkan ke directory dimana file btc.js tersimpan
- Untuk eksekusi ketikan perintah: node btc.js
Code:
const bitcoin = require('bitcoinjs-lib');
const ecc = require('tiny-secp256k1');
const { BIP32Factory } = require('bip32');
const bip32 = BIP32Factory(ecc);
const ParentXPriv = 'xprv9s21ZrQH143K3bSA5miskqop4mNKY86YEpasxCaEwuxyFdJPr5UaqJo3hLBhz91wAQaXZ6hpLE6eEL9qJW7obcWCgpNurQjtqKhqo8TurVA';
const RootKey = bip32.fromBase58(ParentXPriv);
const AccPath = "m/44'/0'/0'";
const AccChild = RootKey.derivePath(AccPath);
const AccXPriv = AccChild.toBase58();
const BIP32Path = "m/44'/0'/0'/0";
const BIP32Child = RootKey.derivePath(BIP32Path);
const BIP32XPriv = BIP32Child.toBase58();
const path44index7 = "m/44'/0'/0'/0/7";
const child44index7 = RootKey.derivePath(path44index7);
const Wif44index7 = child44index7.toWIF();
const path84index0 = "m/84'/0'/0'/0/0";
const child84index0 = RootKey.derivePath(path84index0);
const Wif84index0 = child84index0.toWIF();
const { address } = bitcoin.payments.p2wpkh({ pubkey: child84index0.publicKey });
console.log('Account Xpriv: ' + AccXPriv);
console.log('BIP32 Xpriv: ' + BIP32XPriv);
console.log('WIF-P2PKH (index 7): ' + Wif44index7);
console.log('Bech32 (index 0): ' + address);
console.log('WIF-Bech32 (index 0): ' + Wif84index0);Hasil
