Unity Setup

Estimated time to read: 3 minutes

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.

Prerequisites

To log into the Arcana Developer Dashboard, you’ll need an account with a supported social login or use email for passwordless access.

Google
GitHub
Twitch
Discord

Use https://dashboard.arcana.network to log in with one of the available options.

Welcome screen — Developer Dashboard Login Page

Aggregate Login

The aggregate login feature in the Arcana Auth SDK merges login identities from social providers into one Arcana account if the email ID is the same across these providers. Developers can log into the Arcana Developer Dashboard using any supported provider and still access the same Arcana 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.
