Welcome to WalletConnectUnity Discussions!

👋 Welcome to WalletConnectUnity!

Since we are all Unity developers and we all using this library to either create awesome games or experiences, I thought it'd be a good idea to have a shared place to ask questions, share content and discuss things about WalletConnect in games and WalletConnectUnity in general. We’re using Discussions as a place to connect with other members of the WalletConnectUnity community. We hope that you:

• Ask questions you’re wondering about.
• Share ideas or game projects you are working on.
• Engage with other community members.
• Welcome others and are open-minded. Remember that this is a community we
  build together 💪.

To get started, comment below with an introduction of yourself and tell us about what you are using this library for.

Hello, my name is Josh, and I am excited about this library for use with Unity. I found it while looking for a way to integrate WalletConnect in a project using the Algorand blockchain. I've been able to create transactions in Unity using this Dotnet-Algorand-SDK, but I want to learn how to utilize WalletConnectUnity to further secure the transactions without requiring the user to enter their private key. There is a lot of code to look through and work with, so I'm sure I'll have questions along the way. Thank you for your work on this project!

Hi,
Sorry for the delay on this. The first question I have would be what wallet are you using to test this with? If you make it all the way down to SendRequest and the exception is coming from return await eventCompleted.Task; then that means the wallet is the one that is returning the error. The WalletConnectUnity code will throw an IOException for any error the wallet returns as a response to a Send request.

I tried making some Algorand versions of the Ethereum classes, like an AlgoSendTransaction, AlgoResponse, and a TransactionData class based on Algorand, where I changed its properties to try to match what I was seeing in the examples from other SDKs

This is the correct path to go down to implement this correctly, I think now you need to ensure the final JSON representation of these classes match what the wallet is expecting. This usually manifests in adding [JsonProperty("jsonvarname")] and [JsonIgnore] attributes to your properties. The Send and SendRequest functions in WalletConnectSession performs all the json serializing for you using the standard Newtonsoft.Json library.

Hi,
No problem! I was using the MyAlgo, official Algorand wallet. I did what you suggested and built some custom classes to catch and send the appropriate transaction properties in a Json format. After tweaking things and doing some trial and error, it is now successfully retrieving the signed transactions through WalletConnect, and submitting them through the Dotnet Algorand SDK. Thank you for your help!

Hi,
That's great to hear! I do plan on having extensions on-top of this library to interact with the different blockchain networks (since as you noted, WalletConnect doesn't offer any specific network query abilities). Currently the only extension planned is NEthereum, however it seems Algorand could be another option as well now thanks to your developments :)

If your project is public somewhere, I'll be happy to link to it in this repo for others to find

Hello again! Unfortunately, the project I'm working on isn't public right now, otherwise I would be happy to share the developments we've made for the Algorand side of things. Our game is currently working with Wallet Connect via pc and mac, but we're having trouble initiating a connection to our wallet through Wallet Connect. When we build it for mobile, it jumps straight to the Wallet Connect page of the wallet app on an android phone, but nothing happens after that.

I was wondering if you have any insight into what may be going wrong. I see that in the WalletConnect script, the OpenMobileWallet() and the OpenDeepLink() methods use Application.OpenURL(ConnectURL) to initiate the connection to the wallet. Does the ConnectURL variable need to be configured differently to be used with deeplink? Also, when it does connect, does the rest of the code that handles sending transactions work with that open connection, or is there any additional considerations I need to keep in mind for how requests are being sent over the connection.

I appreciate you help!

[JoshOtter]

Actually, I got it sorted out. We were having an issue where the handshakeID wasn't being generated for some reason, but its working now and the game is able to connect via deep link.

Hi there!

I'm Al, and I may (or potentially not, depending on flakiness - no offence meant) be using WalletConnectUnity in an upcoming game.

The concept of WCU is great, but the implementation is still obviously very much work in progress. What would help me to help you would be if the library code was really well commented. Unfortunately, it's not. This makes it incredibly difficult to troubleshoot when you're up against random behaviour - and also kinda futile because your comments get lost on update.

I would also suggest adding a local websocket server to communicate with wallets safely on the same device - pushing that communication online, encrypted or not, is just such a massive un-safe inefficiency - it should really just all be kept on-device.

Looking forward to working on this with ya!

Thank you for your support + feedback! You are correct that the lack of documentation needs to be fixed, so I'll take time today and tomorrow to go through the code and add documentation as much as I can. This will also be useful because then some documentation pages can be auto generated + annotated for better developer accessibility.

In terms of bugs and stability improvements, I'm torn between polishing this version of the library or starting heavy development on the v2 protocol beta. If you've observed strange behavior or bugs please feel free to log them in the issue tracker for my sake and I'll try to fix them.

In terms of development environment, I do agree that using the production bridges is not ideal at all, perhaps some documentation on how to setup a development bridge server is needed. However last time I looked, I couldn't find a lot of information in general on how to do this for 1.x WalletConnect, I'll look again though

Excited to see what kind of game you'll make with this 😄

Hello!
I am working as part of a team on a game that has successfully used all your great work to allow users to connect with their wallet via the QR code. Now I'm working on putting together a mobile build for the game and am trying to setup a deep link instead. I see that there are methods for OpenMobileWallet and OpenDeepLink but have not been able to get them to trigger properly. Do you have any insight on the best way to transition over to a mobile build or documentation to that effect?

Thanks so much! - Garrett
