Unity Integration

[Tryz]

Hi,

I'm getting stuck with integrating Web3Auth with Unity (stand alone application).

I did the following:

1. Created a Phantom wallet
2. Added the Phantom extension to Chrome
3. Created a Web3Auth account
4. Created a Web3Auth project
5. Added my whitelisted URLs (xxxapp://com.XXX.Web3AuthUnity)
6. Created a Unity project
7. Imported the Web3Auth project
8. Generated a Deep Link (xxxapp://com.XXX.Web3AuthUnity)
9. Opened the sample scene
10. Modified the Web3AuthSample.cs with my clientId and the redirectUrl (xxxapp://com.XXX.Web3AuthUnity/auth)
11. Built the exe

When I run and select Google & Login:

1. A browser opens and shows me my Google account.
2. I log into my Google account
3. I redirect to "https://sdk.openlogin.com/redirect"
4. I'm asked by the browser dialog if I want to open my Web3AuthUnity.exe
5. I press "Open Web3AuthUnity.exe"

Nothing happens. My exe is still sitting on the login screen.

If I browse to "xxxapp://com.XXX.Web3AuthUnity/auth" manually, my app does open to the login screen. So, I know the deep link is there.

In the exe, I never seem to get a return request from the Web3Auth login based on debug lines I log. Maybe my Phantom Wallet isn't tied to my Google account? I'm not getting any kind of error message.

Any help would be super appreciated.

I dont think Phantom Wallet works with native Web3Auth, only our social logins. @hugtor can you help here

Your Phantom wallet can only work with Web3Auth Web using the Phantom Wallet Adapter

For Unity and Mobile SDKs only social logins are supported at this point.

Thank you for the quick replies.

I'm building a Unity (stand alone w/ internet access) client/server prototype... not WebGL or mobile app. Our goal is to have player data on the blockchain (Solana). We also want to have different ways of pushing items into the game for players. Since it's a prototype, I have control over users, wallets, and how we do things. I'm just trying to figure out if we can do it and how. ;)

I was thinking Web3Auth would be a way to authenticate and get a wallet ID. As much as possible, I want to put the work on the server, but we figured there would need to be client approval for our application to access the wallet ID.

I'm hoping you can help me put some pieces together...

• Will social logins give me access to a web3 wallet ID (doesn't have to be Phantom)?
• If there's a way to do what I want, can you help me understand the authentication flow?

This is my first deep dive into web3. So, I might be missing something obvious. I have been reading all your documentation I can find, but my use case is a bit different.

Thank you!

@Tryz How did you solved this ?

I have troubles with unity build for Android.
Social media / gmail Authentication works perfectly on iOS, but on Android, the "redirect to app" button doesnt send the confirmation and doesnt take me back to the app.
When I go back to the app manually, nothing happens ....
Like if the app is not getting a response from web3auth.
The "onLogin" method does not seem to be running
PLEASE HELP 🙏🏼
(working well on iOS)
