Query Balance

This section shows how to connect to Clover mainnet and query the account balance

Prerequisites

Install @polkadot/api, the suggested version is ^4.15.1 (equal or above 4.15.1)

Sample code

const API = require("@polkadot/api")
const cloverTypes = require('@clover-network/node-types');
async function getBalance(address) {
const wsProvider = new API.WsProvider('wss://api-ivy.clover.finance');
const api = await API.ApiPromise.create({
provider: wsProvider,
types: cloverTypes
});
const { parentHash } = await api.rpc.chain.getHeader();
const {
data: { free: balance },
} = await api.query.system.account.at(parentHash, address);
return balance.toString();
}
getBalance('5DZabq7G2m12g1GUuqs66CCAVcmzdWRkXsGxpi4dgXFEcLEb').then(console.log)

Furthermore you may use formatBalance from @polkadot/util to format the display
