Retrieve an Account's Identities
Get the list of Dash Platform Identities associated with an account
Overview
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
- node.js (v12+)
- Basic familiarity with JavaScript asychronous functions using async/await
- The Dash JavaScript SDK is initialized (covered in Connecting to a Network)
- A wallet mnemonic
- A Dash Platform Identity: Tutorial: Register an Identity
Code
Wallet Operations
Currently, the JavaScript SDK does not cache wallet information, and therefore, it re-syncs the entire Core chain for some wallet operations (e.g.
client.getWalletAccount()
). This can result in wait times of 5+ minutes.An upcoming release will add a persistence feature to cache wallet information during initial sync so that subsequent access is much faster. For now, the
skipSynchronizationBeforeHeight
option can be used to only sync the wallet starting at a certain block height.
Dash Platform 0.18 Breaking Change
The derivation path used for identities was updated to align with DIP13 and provide compatibility with the mobile DashPay wallets. Consequently, identities registered with previous versions of the SDK will be not be retrievable.
Also note the change from
account.getIdentityIds()
toaccount.identities.getIdentityIds()
for retrieving identities (PR).
const Dash = require('dash');
const client = new Dash.Client({
network: 'testnet',
wallet: {
mnemonic: 'a Dash wallet mnemonic with testnet funds goes here',
unsafeOptions: {
skipSynchronizationBeforeHeight: 415000, // only sync from start of 2021
},
},
});
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());

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.
