Build Instructions

• Player Settings: Use IL2CPP over Mono when available.
• Build Settings: Use Smaller (faster) Builds / Shorter Build Time for IL2CPP Code Generation.
• Stripping Level: Set Managed Stripping Level to Minimal (Player Settings > Other Settings > Optimization). (Generally not a hard requirement unless using WalletConnect as a wallet provider option.)
• Strip Engine Code: Make sure this is turned off.

• WebGL Template: None enforced, feel free to customize!
• Compression Format: Set to Disabled (Player Settings > Publishing Settings) for final builds.
• Testing WebGL Social Login Locally: Host the build or run it locally with Cross-Origin-Opener-Policy set to same-origin-allow-popups.

Example setup for testing In-App or Ecosystem Wallet Social Login locally:

// YourWebGLOutputFolder/server.js
const express = require("express");
const app = express();
const port = 8000;
 
app.use((req, res, next) => {
  res.header(
    "Cross-Origin-Opener-Policy",
    "same-origin-allow-popups",
  );
  next();
});
 
app.use(express.static("."));
app.listen(port, () =>
  console.log(`Server running on http://localhost:${port}`),
);
 
// run it with `node server.js`

No action needed for hosted builds.

• EDM4U: Comes with the package, resolves dependencies at runtime. Use Force Resolve from Assets > External Dependency Manager > Android Resolver.
• Redirect Schemes: Set custom schemes matching your bundle ID in Plugins/Android/AndroidManifest.xml or equivalent to ensure OAuth redirects if using social login.

<!-- Set your bundle id here -->
<!-- Replace 'com.thirdweb.unitysdk' with your desired scheme -->
<data android:scheme="com.thirdweb.unitysdk" />

If you notice issues with redirects on mobile, for instance hanging after selecting an account when logging in with Google, you did not setup OAuth properly. Best practice is to use a lowercase bundle id that is the same as your Unity project's application identifier, it must be present in the following places:

• Your ThirdwebManager prefab Bundle ID field.
• Your Plugins/AndroidManifest.xml scheme field as mentioned above (it doesn't have to be our default AndroidManifest.xml, it can be in your custom one, just add the scheme).
• Your thirdweb dashboard project settings as one of:
  • Bundle ID Allowlist field (those automatically added to allowed redirect URIs).
  • In-App Wallet Configuration Allowed redirect URIs field.
