Unity Setup

This guide explains how to configure a Unity Web3 app and allow users to sign blockchain transactions using the Arcana wallet.

Use the Arcana Developer Dashboard to first configure user onboarding settings for the Unity app and then integrate the app with the Arcana Auth Unity SDK.


  • To use the Arcana Developer Dashboard, developers can sign in using one of the supported social login providers or opt for passwordless sign-in.

    • Google
    • GitHub
    • Twitch
    • Discord

Go to and log in using one of the available options.

Welcome screen
Developer Dashboard Login Page

Aggregate Login

The Arcana Auth protocol aggregates multiple login identities for the user across social login providers under a single identifiable Arcana account. This enables developers to log into the Arcana Developer Dashboard through any of the supported login providers and access the same Arcana developer account and app settings.

Register App

To register a Web3 Unity app, log into the Arcana Developer Dashboard, create a new app and select the chain that must show up as the default chain in the wallet.

See how to register a new App for details.

Configure App

Refer to the Arcana Developer Dashboard User's Guide and configure the branding, social authentication providers and other settings.
