Integrate Unity App

Estimated time to read: 3 minutes

Integrate 'Unity' apps with Arcana Auth SDK and onboard users via social login. Enable users to sign blockchain transactions with the in-app Arcana wallet.

Prerequisites

Register the 'Unity' app and configure SDK usage settings for social login providers, manage app manage app chains and wallet user experience.

Non-EVM Chains

When registering an app through Arcana Developer Dashboard, the choice of chain type (EVM, Solana, MultiversX, Near) is final. App developers can't change it later. They can switch the default chain within the same type. For example, a Solana app on Testnet can switch to Solana Mainnet or Solana Dev but not to MultiversX or an EVM chain.

Steps

1. Setup

Setup Unity

Install NuGetForUnity.
In the NuGet Toolbar at the top, click NuGet > Manage NuGet packages.

Install the following packages by STA: Nethereum.Web3, WebsocketSharp.Core
Use the Unity Editor Project Settings window to edit package settings for your project. Click Edit > Project Settings > Package Manager.
- Edit Project Settings with URL https://npm-registry.arcana.network/ and set the scope to com.cysharp.unitask, dev.voltstro
  Edit Project Settings
- Add another new scoped registry with URL https://unitynuget-registry.azurewebsites.net and set the scope to org.nuget.
  Add Scoped Registry
In the NuGet window, use the NuGet Toolbar at the top, and click Window > Package Manager > Add Package by Name.
Add Package by Name
Add the following packages: com.cysharp.unitask, `dev.voltstro.unitywebbrowser.engine.cef
