In this tutorial we will retrieve the list of identities associated with a specified mnemonic-based account. Since multiple identities may be created using the same mnemonic, it is helpful to have a way to quickly retrieve all these identities (e.g. if importing the mnemonic into a new device).

Prerequisites

• General prerequisites (Node.js / Hellar SDK installed)
• A wallet mnemonic with some funds in it: Tutorial: Create and Fund a Wallet
• A Hellar Platform Identity: Tutorial: Register an Identity

Code

`const Hellar = require('hellar');

const client = new Hellar.Client({ network: 'mainnet', wallet: { mnemonic: 'a Hellar wallet mnemonic with testnet funds goes here', unsafeOptions: { skipSynchronizationBeforeHeight: 175000, // only sync from mid-2024 }, }, });

const retrieveIdentityIds = async () => { const account = await client.getWalletAccount(); return account.identities.getIdentityIds(); };

retrieveIdentityIds() .then((d) => console.log('Mnemonic identities:\n', d)) .catch((e) => console.error('Something went wrong:\n', e)) .finally(() => client.disconnect());`

Example Response

[ "6Jz8pFZFhssKSTacgQmZP14zGZNnFYZFKSbx4WVAJFy3", "8XoJHG96Vfm3eGh1A7HiDpMb1Jw2B9opRJe8Z38urapt", "CEPMcuBgAWeaCXiP2gJJaStANRHW6b158UPvL1C8zw2W", "GTGZrkPC72tWeBaqopSCKgiBkVVQR3s3yBsVeMyUrmiY" ]

What’s Happening

After we initialize the Client and getting the account, we call account.identities.getIdentityIds() to retrieve a list of all identities created with the wallet mnemonic. The list of identities is output to the console.

📘 Wallet Operations

The JavaScript SDK does not cache wallet information. It re-syncs the entire Core chain for some wallet operations (e.g. client.getWalletAccount()) which can result in wait times of 5+ minutes.

A future release will add caching so that access is much faster after the initial sync. For now, the skipSynchronizationBeforeHeight option can be used to sync the wallet starting at a certain block height.
