1. Download: Head over to the releases page and download the latest .unitypackage file.
2. Explore: Try out Scene_Playground to explore functionality and get onboarded.
3. Learn: Explore the Unity v5 SDK Docs and the .NET SDK Docs to find a full API reference.

Notes:

• Tested on Unity 2021.3+, 2022.3+, Unity 6 Preview. We recommend using 2022 LTS.
• Newtonsoft and EDM4U are included utilities; deselect if already installed to avoid conflicts.
• If using .NET Framework and encountering HttpUtility errors, create csc.rsp with -r:System.Web.dll under Assets.
• Use version control and test removing duplicate DLLs if conflicts arise.

• Build Settings: Use Smaller (faster) Builds / Shorter Build Time.
• Player Settings: Use IL2CPP over Mono when available.
• 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.)

• 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 (no longer required with Unity 6 Web, can use Build & Run):

// 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/AndroidManifest.xml or equivalent to ensure OAuth redirects.
