Sorting through HD wallets

Question

I created a random HD address using my seed phrase a while back. lets call it 0x1....I then send funds to the wallet and continued using it normally. I have since lost the devise i had generated the random HD address 0X1.... I still have my recovery phrase and I remember the address 0x1.. Is there a way I can sort through all my randomly created on my HD wallet to get back my address 0x1.. I do not have a private key for this address.I could have pasted the seed phrase on metamask to recreate the address but i have to keep generating addresses until it which could take ages.

Answer 1

I could have pasted the seed phrase on metamask to recreate the address but i have to keep generating addresses until it which could take ages.

That'd be one way to go, yes. Alternatively, you can write code that does that for you. This would work, using the ethers.js library :

const phrase = 'YOUR_SEED_PHRASE';
const wantAddress = 'YOUR_ADDRESS';

let wallet;
let currentAddress;
let i = 0;

while(1) {
    const path = `m/44'/60'/0'/0/${i}`;
    wallet = ethers.Wallet.fromMnemonic(phrase, path);
    currentAddress = wallet.address;
    
    if (currentAddress.toLowerCase() === wantAddress.toLowerCase()) {
        console.log('Match found:', currentAddress);
        console.log('Private Key:', wallet.privateKey);
        break;
    }
    i++;
}

Answer 2

const crypto = require('crypto');
const HDKey = require('hdkey');

const phrase = 'YOUR_SEED_PHRASE';
const wantAddress = 'YOUR_ADDRESS';

async function recoverWallet() {
  let i = 0;
  const progressInterval = 1000; // Adjust this value to update the progress indicator frequency

  console.log('Starting brute force...');

  while (true) {
    const seed = crypto.createHash('sha256').update(phrase).digest();
    const masterNode = HDKey.fromMasterSeed(seed);
    const derivedNode = masterNode.derive(`m/44'/60'/0'/0/${i}`);
    const currentAddress = derivedNode.publicKey.toString('hex');

    if (currentAddress.toLowerCase() === wantAddress.toLowerCase()) {
      console.log('Match found:', currentAddress);
      console.log('Private Key:', derivedNode.privateKey.toString('hex'));
      return;
    }

    if (i % progressInterval === 0) {
      console.log('Progress:', i);
    }

    i++;
  }
}

recoverWallet().catch((error) => {
  console.error('Error occurred during wallet recovery:', error);
});
