Get and display accounts and balances

Get accounts

You can use the Accounts package to work with accounts easily.

The package allows connecting with different accounts. To get an accounts list, you need to create an instance of the Accounts class and connect the necessary providers to it:

import { Accounts } from '@unique-nft/accounts';
import { KeyringLocalProvider } from '@unique-nft/accounts/keyring-local';
import { PolkadotProvider } from '@unique-nft/accounts/polkadot';

const accounts = new Accounts();
await accounts.addProvider(KeyringLocalProvider);
await accounts.addProvider(PolkadotProvider);

const accountsList = await accounts.getAccounts();

This will give us a list of available accounts. You can read a little more about accounts in the Polkadot docs - Keyring and Extension.

Get balances

To get the balance of available accounts, we need to use SDK. All we need to do is to pass the account address, whose balance we want to know, as an argument.

import Sdk, { Options } from '@unique-nft/sdk';

const options: Options = {
    baseUrl: '<REST API URL>'
};
const sdk = new Sdk(options);

const { address, availableBalance, lockedBalance, freeBalance } = sdk.balance.get({ address });

As a result, we get the following data:

address - current address.

availableBalance - transferable balance.

lockedBalance - locked balance.

freeBalance - full balance.
