Lab 9 : Recover wallet and regenerate account.

This lab is a learn about the behavior of recovery wallets and regenerate accounts.

//= ============ Recover wallet and regenerate account =============//
console.log('Recover wallet and regenerate account');

const accountKey = await algo.kmd.exportKey(walletHandle, password, address);
const mn = await algo.sdk.secretKeyToMnemonic(accountKey.private_key);

const mdk = await algo.sdk.mnemonicToMasterDerivationKey(mn);
// console.log('MDK:', mdk);

walletNumber = faker.random.number() + '-wallet';
console.log('New Wallet:', walletNumber);

walletId = (await algo.kmd.createWallet(walletNumber, password, mdk)).wallet.id;
console.log('New ID:', walletId);

walletHandle = (await algo.kmd.initWalletHandle(walletId, password)).wallet_handle_token;
console.log('Got new wallet handle:', walletHandle);

const recAddr = (await algo.kmd.generateKey(walletHandle)).address;
console.log('Recovered account: ', recAddr);

NOTE :

To recover a wallet and any previously generated accounts, use the wallet backup phrase (also called the wallet mnemonic or passphrase). The master derivation key for the wallet will always generate the same addresses in the same order. Therefore the process of recovering an account within the wallet looks exactly like generating a new account.

An offline wallet may not accurately reflect account balances, but the state for those accounts (e.g. its balance, online status) are safely stored on the blockchain. kmd will repopulate those balances when connected to a node.

Step 1 : Start Lab

cd algo.labs
./algo.sh lab9

OR

cd algo.labs/lab9.recover-wallet
node index.js

Output

Create a wallet and generate an account.
