From mnemonic passphrase to bitcoin wallet address

[didotsonev]

Goal

I'm trying to create a script which converts mnemonic BIP39 12 words passphrase to bitcoin (exodus) wallet address.

Script (from issue in this repo)

const Bitcoin = require('bitcoinjs-lib');
const Bip39 = require('bip39');
const Bip32 = require('bip32');

function getAddress (node, network) {
  return Bitcoin.payments.p2pkh({ pubkey: node.publicKey, network }).address
}

const mnemonic = `some mnemonic`;
const seed = Bip39.mnemonicToSeedSync(mnemonic);
const root = Bip32.fromSeed(seed, Bitcoin.networks.bitcoin);
const child1 = root.derivePath("m/44'/0'/0'/0/0");
const child2 = root.deriveHardened(44).deriveHardened(0).deriveHardened(0).derive(0).derive(0);

console.log(getAddress(child1));
console.log(getAddress(child2));

While I send the correct mnemonic I don't get the expected addres. Do I miss some convertion or?

Other scripts I tried: https://bitcoin.stackexchange.com/a/75334 https://github.com/bitcoinjs/bitcoinjs-lib/issues/997#issuecomment-360706692

Use BIP84 not BIP44. (the derivation path) Use p2wpkh not p2pkh.

It works now. Thank you.

End result (for anyone reading)

const bitcoin = require('bitcoinjs-lib');
const bip39 = require('bip39');
const bip32 = require('bip32');

function getAddress (node, network) {
  return bitcoin.payments.p2wpkh({ pubkey: node.publicKey, network }).address
}

const mnemonic = `fsome mnemonic`;

const seed = bip39.mnemonicToSeedSync(mnemonic);

const root = bip32.fromSeed(seed, bitcoin.networks.bitcoin);

const child1 = root.derivePath("m/84'/0'/0'/0/0");
const child2 = root.deriveHardened(84).deriveHardened(0).deriveHardened(0).derive(0).derive(0);

console.log(getAddress(child1));
console.log(getAddress(child2));

Hello! It doesnt work now:

TypeError: Cannot read property 'p2wpkh' of undefined

[junderw]

Yes it still does.

Please check to make sure you are importing the bitcoinjs-lib library to bitcoin variable, and make sure the version of bitcoinjs-lib is the correct version (v4.x.x and above)

[TheRadioGuy]

Yep, it was an old version :D

By the way, what's the difference between child1 and child2?

[junderw]

Nothing, they are the same. I was just showing 2 ways to get the same result.

[TheRadioGuy]

Thanks you!

It's me again. I have the code above and it generates "bc1..." address. Can I get address as "1Avqtgyqd81DEcRYcDkjf1dQdhf3H7Rd5V"?

[junderw]

p2wpkh -> p2pkh
"m/84'/0'/0'/0/0" -> "m/44'/0'/0'/0/0"

I didn’t get it right away, but this option helped.

const bip39 = require('bip39');
const ecc = require('tiny-secp256k1')
const { BIP32Factory } = require('bip32')
const bip32 = BIP32Factory(ecc);
const bitcoin = require('bitcoinjs-lib');

function getAddress (node, network) {
    return bitcoin.payments.p2wpkh({ pubkey: node.publicKey, network }).address
}

const mnemonic = `fsome mnemonic`;

const seed = bip39.mnemonicToSeedSync(mnemonic);

const root = bip32.fromSeed(seed, bitcoin.networks.bitcoin);

const child1 = root.derivePath("m/84'/0'/0'/0/0");
const child2 = root.deriveHardened(84).deriveHardened(0).deriveHardened(0).derive(0).derive(0);

console.log(getAddress(child1));
console.log(getAddress(child2));

console.log(getAddress(child1));
console.log(getAddress(child2));

When I run this code, I got an error below.

What's wrong?

[junderw]

What's wrong?

The example is based off of the version that was out at the time. Since then all of these libraries have release major version updates that changed the API.

[ROHITTH-C]

use

const ecc = require('tiny-secp256k1') const { BIP32Factory } = require('bip32') // You must wrap a tiny-secp256k1 compatible implementation const bip32 = BIP32Factory(ecc)

With this you should be able to access these methods.

fromSeed, fromBase58, fromPublicKey, fromPrivateKey
