2. Add a new scoped registry with the following details:
   • Name: OpenUPM
   • URL: https://package.openupm.com
   • Scope(s): com.reown and com.nethereum
3. Press plus ➕ and then Save buttons

Configure

The minimum configuration required is filling in a Project ID and Metadata fields inside of AppKitConfig.

Don't have a project ID?

Head over to Reown Dashboard and create a new project.

await AppKit.InitializeAsync(
    new AppKitConfig(
        projectId: "YOUR PROJECT ID",
        new Metadata(
            name: "My Game",
            description: "Short description
            url: "https://example.com",
            iconUrl: "https://example.com/logo.png"
        )
    )
);

• projectId: The project ID is a unique identifier for your project.
  • If you don’t have a Project ID, you can create one at Reown Dashboard.).
• name: The project name is a human-readable name for your project.
• description: The project description is a human-readable description for your project.
• url: The project URL
• iconUrl: Icon of the project.

Implement

1. Add Reown AppKit prefab from Packages/Reown.AppKit.Unity/Prefabs to your scene.
2. Initialize Reown from your script

public async void Start()
{
    var config = new AppKitConfig(...);
    await AppKit.InitializeAsync(config);
}

3. Connect account

public async Task ResumeSession()
{
    // Try to resume account connection from the last session
    var resumed = await AppKit.ConnectorController.TryResumeSessionAsync();

    if (resumed)
    {
        // Continue to the game
        MyAccountConnectedHandler();
    }
    else
    {
        // Connect account
        AppKit.AccountConnected += (_, e) => MyAccountConnectedHandler();
        AppKit.OpenModal();
    }
}

Optional: Using Solana Unity SDK? You can keep using Solana.Unity.SDK’s Web3 and route all signing through Reown with our adapter. See the adapter section in Usage.
