0xchat uses the NIP-51 list to store the encrypted contact list.

Please let me know if you’re unable to receive push notifications properly.

Good point! XChat is set up with one relay per circle, but you can switch between circles (relays).
XChat is more focused on small, private groups, while White Noise seems to aim for larger crowds. That’s why XChat tries to use a single relay and keeps key packages away from the relay — we only share them via QR codes

It's supposed to be. Once White Noise releases a stable version, compatibility testing will be conducted.
And GM - forgot to say earlier 🙂

XChat is a standalone app (based on MLS), not compatible with 0xchat.

Yes, the desktop version is in the plans.

I haven’t solved this problem yet. Right now, the push notifications sent to clients are just something like: “You received a private message.”
I do have a potential solution in mind: the push notification could include the eventid. Then, once the client receives the notification, it could activate for a short period of time to fetch the event, decrypt it, and display the actual content to the user.
However, I haven’t implemented this approach yet — it still needs to be tested and verified.

Amber is an Android native client used as a nostr signing tool. I strongly recommend using it for logging in.
If you are using a different signing client, you can directly enter the bunker:// link on the login page.

I have restarted the server. It should works now.

Is it a nip29 group? Other non-admin members don’t need to update the app.
Also, are you referring to the group’s historical messages not loading?

I think this issue started after I updated the new NIP-29 relay implementation — I’ll look into it. Thanks for pointing it out!

Currently, the push server only pushes messages from the 0xChat relay.
