Quick Start: Web3-React Apps

Web3 apps using 'Web3-React' framework can easily onboard users via social login by integrating with the Arcana Auth Web3 React SDK!


1. Register & Configure

Log into the Arcana Developer Dashboard:

In the Manage Apps dashboard screen, click the first card and create a new app entry to register app. Each app is assigned a unique Client ID at registration. The Client ID is required for integrating the app with the Arcana Auth SDK.

A default Testnet configuration profile is associated with the registered app. In the Manage Apps dashboard screen, select the registered app card and click 'Testnet' configuration settings. Choose Social Auth to configure user onboarding providers. Optionally enable gasless transactions in Arcana wallet to incentivize app users.

2. Install SDKs

For 'Web3-React' app, install the following packages:

npm install --save @arcana/auth-web3-react @arcana/auth
yarn add @arcana/auth-web3-react @arcana/auth
<script src=""></script>
<script src=""></script>
<script src=""></script>
<script src=""></script>

Use latest SDKs

Use the latest Arcana Auth SDK release: v1.0.10. Migrate from Arcana Auth SDK v1.0.9 -> v1.0.10.

Versions older than Arcana Auth SDK v1.0.9 may encounter potential breaking changes that require app reconfiguration, integration code updates, and redeployment. Refer to the Migration Guides and Release Notes.

In addition to the latest Arcana Auth SDK, for Web3-React apps, you must also use the latest Arcana Auth Web3 React SDK release: v0.0.1

3. Integrate

Import AuthProvider from the auth package.

const { AuthProvider } = window.arcana.auth // From CDN
import { AuthProvider } from '@arcana/auth' //From npm

Create a new AuthProvider instance. Specify the unique Client ID obtained during the app registration.

const auth = new AuthProvider(
  "xar_test_445007f942xxxxxxxxxxxxxxxxxx484cAfd2", // App client ID
    position: 'left',         // default: right
    theme: 'light',           // default: dark
    alwaysVisible: false,     // default: true, wallet always visible
    setWindowProvider: true,  // default: false, window.ethereum not set
    connectOptions: {
      compact: true           // default: false, regular plug-and-play login UI
    chainConfig: {
      chainId: '137',                    // defaults to Ethereum
      rpcUrl: '', // defaults to ''
AuthProvider Optional Parameters

You can optionally customize the following settings in the AuthProvider constructor:

alwaysVisible: Arcana wallet visibility mode - always visible in the app context or only if a blockchain transaction is triggered by the app

chainConfig: use chainId to specify the chain identifier for the active chain in the wallet and rpcUrl for specifying the RPC Url for that chain identifier

position: wallet position within the app context - left|right

theme: wallet theme - light|dark

setWindowProvider: set window.ethereum in the app context with the standard EIP-1193 Ethereum provider value

connectOptions: built-in login UI compact mode - true|false

See AuthProvider constructor parameters for details.

Next, import the ArcanaConnector from the auth-web3-react package.

Initialize the ArcanaConnector by specifying the AuthProvider created earlier:

import { initializeConnector } from "@web3-react/core";
import { ArcanaConnector } from "@arcana/auth-web3-react";
import { AuthProvider } from "@arcana/auth";
import { URLS } from "../chains";

const auth = new AuthProvider(
export const [arcanaConnect, hooks] = initializeConnector<ArcanaConnector>(
  (actions) =>
    new ArcanaConnector(auth, {

The app is now integrated with the Arcana Auth SDK and the Arcana Auth Web3 React SDK. Use React hooks to enable AuthProvider functions via the ArcanaConnector.

import { useEffect, useState } from "react";

import { MAINNET_CHAINS } from "../../chains";
import { hooks, arcanaConnect } from "../../connectors/arcanaWallet";
import { Card } from "../Card";

const CHAIN_IDS = Object.keys(MAINNET_CHAINS).map(Number);

const {
} = hooks;

export default function ArcanaConnectCard() {
  const chainId = useChainId();
  const accounts = useAccounts();
  const isActivating = useIsActivating();

  const isActive = useIsActive();

  const provider = useProvider();
  const ENSNames = useENSNames(provider);

  const [error, setError] = useState(undefined);

  // attempt to connect eagerly on mount
  useEffect(() => {
    arcanaConnect.connectEagerly().catch((error) => {
      console.debug("Failed to connect eagerly to arcanaConnect", error);
  }, []);

  return (

Onboard Users

import { initializeConnector } from "@web3-react/core";
import { ArcanaConnector } from "@arcana/auth-web3-react";
import { AuthProvider } from "@arcana/auth";
import { URLS } from "../chains";

const auth = new AuthProvider(
export const [arcanaConnect, hooks] = initializeConnector<ArcanaConnector>(
  (actions) =>
    new ArcanaConnector(auth, {
Custom Login UI

You can onboard users through a custom login UI instead of the built-in plug-and-play one. See how to use custom login UI for onboarding users in a 'Web3-React' app for details.

Arcana JWT Token

Upon successful authentication, Arcana Auth SDK returns a unique JWT token to the app called the Arcana JWT Token. App developers can use this token to verify user login and subsequently generate another token for app use. Learn more about how to verify the Arcana JWT Token for apps deployed on Testnet and Mainnet.

Sign Transactions

Use the standard JSON RPC Web3 wallet operations supported by the AuthProvider.

Manage the user experience for signing blockchain transactions by choosing the default, built-in Arcana wallet UI and tinkering with the wallet visibility or selecting a custom wallet UI.

4. Deploy

Finally, deploy the app on Testnet (default). For Mainnet deployment, see Testnet > Mainnet Migration Guide.

That's all!

Your 'Web3-React' app is now powered by Arcana Auth SDK and Arcana Auth Web3 React SDK to onboard users via social login and sign blockchain transactions using Arcana wallet.
