Mobile (WalletConnect) / Coming Soon


WalletConnect is an open source protocol for connecting DAPPs to mobile wallets with QR code scanning or deep linking.

There are two common ways to integrate:

1. Web3Modal

Web3Modal is an easy-to-use library to help developers add support for multiple providers (including WalletConnect) in their apps with a simple customizable configuration.


npm install --save web3modal web3 @walletconnect/web3-provider

Customize chain id

Sample code for configuring WalletConnect with Bitrock Blockchain

import Web3 from "web3";
import WalletConnectProvider from "@walletconnect/web3-provider";
import Web3Modal from "web3modal";

// set chain id and rpc mapping in provider options
const providerOptions = {
  walletconnect: {
    package: WalletConnectProvider,
    options: {
      rpc: {
        7171: "",
      chainId: 7171,

const web3Modal = new Web3Modal({
  network: "mainnet", // optional
  cacheProvider: true, // optional
  providerOptions, // required

const provider = await web3Modal.connect();
await web3Modal.toggleModal();

// regular web3 provider methods
const newWeb3 = new Web3(provider);
const accounts = await newWeb3.eth.getAccounts();


2. Standalone Client

Bitrock Wallet extends WalletConnect 1.x with aditional JSON-RPC methods to support multi-chain dApps. Currently, you can get all accounts and sign transactions for Bitrock Blockchain implements signJSON method in wallet core.


npm install --save @walletconnect/client @walletconnect/qrcode-modal

Initiate Connection

Before you can sign transactions, you have to initiate a connection to a WalletConnect bridge server, and handle all possible states:

import WalletConnect from "@walletconnect/client";
import QRCodeModal from "@walletconnect/qrcode-modal";

// Create a connector
const connector = new WalletConnect({
  bridge: "", // Required
  qrcodeModal: QRCodeModal,

// Check if connection is already established
if (!connector.connected) {
  // create new session

// Subscribe to connection events
connector.on("connect", (error, payload) => {
  if (error) {
    throw error;

  // Get provided accounts and chainId
  const { accounts, chainId } = payload.params[0];

connector.on("session_update", (error, payload) => {
  if (error) {
    throw error;

  // Get updated accounts and chainId
  const { accounts, chainId } = payload.params[0];

connector.on("disconnect", (error, payload) => {
  if (error) {
    throw error;

  // Delete connector

Get chain accounts from Bitrock Wallet

Once you have walletconnect client set up, you will be able to get user's accounts:

const request = connector._formatRequest({
  method: "get_accounts",

  .then((result) => {
    // Returns the accounts
  .catch((error) => {
    // Error returned when rejected

The result is an array with following structure:

    network: number,
    address: string,
