Web3Auth Unity SDK

Web3Auth is where passwordless auth meets non-custodial key infrastructure for Web3 apps and wallets. By aggregating OAuth (Google, Twitter, Discord) logins, different wallets and innovative Multi Party Computation (MPC) - Web3Auth provides a seamless login experience to every user on your application.

⏪ Requirements

Unity Editor 2019.4.9f1 or greater
.Net Framework 4.x

⚡ Installation

Download .unitypackage and import the package file into your existing Unity3D project.

You may encounter errors when importing this package into your existing project. The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?) To fix this problem you need to add the following line into dependencies object which is inside the Packages/manifest.json file.

"com.unity.nuget.newtonsoft-json": "2.0.0"

🌟 Configuration

To get started, open a sample scene Web3AuthSample inside Assets/Plugins/Web3AuthSDK/Samples/Web3AuthSample.scene

Before building the application for Android/IOS you need to register the redirect_uri which can be done easily by the tool provided inside the SDK. To achieve that, you need to follow the steps mentioned below.

Open deep link generator tool provided by Web3Auth Unity SDK from "Window > Web3Auth > Deep Link Generator"
Enter the redirect_url (i-e torusapp://com.torus.Web3AuthUnity/auth) and click generate.

To use your own client_id , register your app on https://web3auth.io/ and replace the client_id inside Assets/Plugins/Web3AuthSDK/Samples/Web3AuthSample.cs script.

Configure an Web3Auth project

Go to Developer Dashboard, create or select an Web3Auth project:

Add {{SCHEMA}}://{YOUR_APP_PACKAGE_NAME}://auth to Whitelist URLs. i-e torusapp://com.torus.Web3AuthUnity/auth
Copy the Project ID for later usage as client_id

💥 Initialization & Usage

In your sign-in script', create an Web3Auth instance with your Web3Auth project's configurations and configure it like this:

Web3Auth web3Auth = new Web3Auth(new Web3AuthOptions() {
  redirectUrl = new Uri("torusapp://com.torus.Web3AuthUnity/auth"),
    clientId = "BAwFgL-r7wzQKmtcdiz2uHJKNZdK7gzEf2q-m55xfzSZOw8jLOyIi4AVvvzaEQO5nv2dFLEmf9LBkF8kaq3aErg",
    network = Web3Auth.Network.TESTNET,
    whiteLabel = new WhiteLabelData() {
      name = "Web3Auth Sample App",
        logoLight = null,
        logoDark = null,
        defaultLanguage = "en",
        dark = true,
        theme = new Dictionary < string, string > {
          {
            "primary",
            "#123456"
          }
        }
    }
});
web3Auth.onLogin += onLogin;
web3Auth.onLogout += onLogout;
private void onLogin(Web3AuthResponse response) {
    // Handle user signing in
}
private void onLogout() {
  // Handle user signing out
}

Simulate redirect callback inside Unity Editor

Web3Auth Unity SDK provides a tool to simulate the redirect callback. To open go to "Window > Web3Auth > Debug Deep Link" and paste the redirect uri (it must include the response code)
