Thirdweb Unreal Engine SDK Plugin

A Code Plugin for Unreal Engine that enables developers to create thirdweb Private Key Wallets, In-App Wallets and Smart Wallets for their games and applications. The plugin provides a simple API and blueprints to interact with wallets, login with email or socials as well as create Smart Wallet session keys.

With this plugin, you can keep the onboarding of your users in-client and grant a session key to your thirdweb Engine powered backend to interact with the blockchain, no signature in sight.

Supported Unreal Engine Versions

Thirdweb adheres to Unreal Engine's Marketplace Guidelines in supporting the 3 most recent versions¹. We aim to release an updated plugin version as expediently as possible once a minor version change has released. If you or your company require compatibility with an older version, please reach out to support.

Installation

In addition to the source code provided, the plugin is available on the Unreal Marketplace.

The plugin's core logic is built from Rust, making it lightning-fast and minimizing the clutter in your Unreal project.

Packaging

Windows, Linux, and Android all package natively and can be used in blueprint-only projects

Mac

The plugin currently makes use of the Web Browser runtime module which bundles CEF3. Changes to the engine are currently required for modern xcode targets as Unreal Engine does not properly link the framework during packaging. This requires either an engine patch or moving the framework post-build and then codesigning your build again.

In the CEF3.build.cs you need to bypass the if check for modern xcode. This can be accomplished by adding || true to the end of the if check on line 102.

Additionally, you need to add bCompileCEF3 = true; to your build target
