WalletConnectUnity

This project is an extension of WalletConnectSharp that brings WalletConnect to Unity. This project has been built using Unity 2019.4.28f1 (LTS), and has been tested using 2020.1.14f1.

This project includes a working demo scene (TODO: needs to show sample transactions)

⚠️ This is beta software: This software is currently in beta and under development. Please proceed with caution, and open a new issue if you encounter a bug ⚠️

Installation

To use WalletConnectUnity, you would need Unity2019.4.28f1 or above.

After making a new project in Unity, you will need to download WalletConnectUnity from this repo by cloning it, forking it, or downloading as a zip file. Take the contents of the Assets folder in the repo and place it in your Unity Project.

Once imported in your Unity Project, create a game object in your scene named Wallet Connect and attach the Wallet Connect component to the your new game object. You can configure both the connection settings and app details in the Wallet Connect Component.

Usage

To use WalletConnect in your Unity project, simply create an empty GameObject in your Scene and attach the WalletConnect component to your GameObject. Attaching this script will automatically attach any required components as well

QRCode Generation

This project comes with a component to automitcally generate a QR Code image and place it onto a UI Image. To do this, simply attach the WalletConnect QR Image component to your Image and select your WalletConnect GameObject reference

API

To access the current WalletConnect object in any Scene, you can do WalletConnect.Instance. This object will include a reference to the WalletConnectProtocol object, the Connection URL and some helper functions. For reference on how to use the WalletConnectProtocol object, see WalletConnectSharp for more details.

NEthereum

Currently, this project DOES NOT include the NEthereum Extension. To add the extension, simply add the WalletConnect.NEthereum folder from WalletConnectSharp and then include the proper NEthereum Unity libraries in your project.

Once you have done this, to create a new NEthereum Web3 instance, you can simply do

var wcProtocol = WalletConnect.Instance.Protocol
var web3 = new Web3(wcProtocol.CreateProvider(new Uri("https://mainnet.infura.io/v3/<infruaId>"));
