Read a Koin balance:

Using as a CommonJS library

import { ChainIds, Methods, WebWalletConnectKoinos } from "@armana/walletconnect-koinos-sdk-js"
import { Contract, utils } from "koilib"

(async () => {
  // Get your projectId by creating a free WalletConnect cloud project at https://cloud.walletconnect.com
  const projectId = "..."

  // create WalletConnectKoinos
  const walletConnectKoinos = new WebWalletConnectKoinos(
    {
      projectId,
      // your application information
      metadata: {
        name: "Web3Modal",
        description: "Web3Modal",
        url: "web3modal.com",

      modalOptions: {
        explorerRecommendedWalletIds: "NONE",
        enableExplorer: false,
      },
    }
  );

  // initiate connection with a wallet
  const accounts = await walletConnectKoinos.connect(
    [ChainIds.Harbinger],
    [
      Methods.ReadContract,
    ]
  );
  console.info(accounts);

  const provider = walletConnectKoinos.getProvider()

  // get Koin balance on Mainnet
  const koin = new Contract({
    // Mainnet
    // id: "15DJN4a8SgrbGhhGksSBASiSYjGnMU8dGL",

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

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