Thx, and do you have successfully connected to 0xchat relay? wss://relay.0xchat.com

Hey the issue has been fixed in the v1.3.1-beta.3

2024-08-27 13:52:22

- reply

Maybe there’s a bug on our client side. No worries, we’re looking into it. Will let you know once it’s fixed.

Oh… are you using the latest v1.3.1-beta version?

2024-08-26 17:35:28

- reply

Most of the nostr clients do not support NIP-29 event yet. We are the very first client to fully support NIP-29 group.

2024-08-24 00:01:39

- reply

Unfortunately, it's no longer available to prevent users from accidentally sending an unwrapped DM. Perhaps you could use another client to notify the other person

2024-08-23 11:36:05

- reply

Yes, exactly! The app doesn't depend on us running specific relays. This gives you the flexibility to use other relays or even set up your own if you prefer.

2024-08-23 02:21:10

- reply

No worries.
Every time you make a voice or video call, you need to use Nostr relays (in this case, your general relays) for signaling communication.

2024-08-22 17:44:52

- reply

It works mostly like that, we use NIP-100 for signaling through Nostr relays, then we utilize the ICE server for STUN or TURN.
In our latest version, you can also choose to "always use relay" to prevent the IP from being exposed to your contacts.

-Join requests have to be repeated nearly every time
Oh, is this referring to bugs in 0xChat?

2024-08-14 17:32:48

- reply

Secret chat is based on Giftwrapped DM, using temporary keys to send and receive messages to enhance privacy. Note that messages in secret chat cannot be recovered on other devices or Nostr clients.

Sorry, our technical solution for this private group is suitable for small groups, not for large group chats like Telegram. Of course, changing the group avatar could include this feature, but having multiple administrators is too complicated for small group chats.

It's private. We use NIP-17 as our default DM type, and we also support private group and public channel features. Let me know if you have any problems when using it. :)

Is he also using 0xchat, or is it another client? Additionally, if the other person is not in your contacts, the default message will appear in the 'Stranger' conversation. You can click to enter and see the chat messages

Thank you for trying out our app. We are continually making improvements.
To be honest, our approach with nip101 is significantly different from Sealed Gift-Wrapped. While Sealed Gift-Wrapped hides metadata, we don't attempt to do so(metadata help the client subscribe to appropriate events). However, during private chats with friends, we use an alias pubkey to replace the real pubkey. This way, even if a third party obtains the metadata, they won't be able to tell who is chatting with whom.
And this is just the implementation approach of our app.
