Great idea, thanks for tracking. Any interest in doing a PR? :)

[SonOfMosiah]

Absolutely. I'll try my hand at adding this in.

[shazow]

Fantastic! Let me know if you have any trouble getting going, I'd like to make callthis more contributor-friendly.

[shazow]

Added a manifest in 790fb9c, pretty sure it's working now? Didn't need to do anything special for the provider.

[SonOfMosiah]

I think Safe also requires the app to "eager connect" or "auto connect" to the safe wallet.

[shazow]

@SonOfMosiah Does it not work for you rn? I think whatever I did for my custom wallet connecting happened to be compatible with what Safe does. 🙃

[SonOfMosiah]

Is the latest live on callthis.link? Wasn't able to connect through app.safe.global

[shazow]

Ah you're right, it looked like it was working but it was using the wrong wallet.

I think it's actually also a CORS issue at the moment.

[shazow]

Do you have any (working) links handy for how eager/auto connect is supposed to work? Looks like everything is 404 these days. -_-

[shazow]

Ah found it via archive.org https://github.com/safe-global/safe-apps-sdk/tree/main/packages/safe-apps-provider

[shazow]

Alright that was more annoying than I hoped but should do the trick, can you confirm when you get a chance? @SonOfMosiah
