Read a Koin balance:

Using as a CommonJS library (React, Vue, etc...)

import MyKoinosWallet from '@roamin/my-koinos-wallet-sdk'
import { Contract, utils } from "koilib"

(async () => {
  const walletConnectorUrl = 'https://my-koinos-wallet.vercel.app/embed/wallet-connector'

  const mkw = new MyKoinosWallet(walletConnectorUrl)
  await mkw.connect()

  // request permissions to access some of the My Koinos Wallet APIs
  const acceptedPermissions = await mkw.requestPermissions({
    'accounts': ['getAccounts'],
    'provider': ['readContract']
  })

  const accounts = await mkw.getAccounts()

  const provider = mkw.getProvider()

  // get Koin balance on Mainnet
  const koin = new Contract({
    // Mainnet
    // id: "15DJN4a8SgrbGhhGksSBASiSYjGnMU8dGL",
    // Harbinger Testnet
    id: "19JntSm8pSNETT9aHTwAUHC5RMoaSmgZPJ",
    abi: utils.tokenAbi,
    provider,
  })

  // Get balance
  const { result: { value } } = await koin.functions.balanceOf({
    owner: accounts[0].address,
  })

  console.log(`Balance of account ${accounts[0].address} is ${utils.formatUnits(value, 8)} Koin`)
})();
