It’s hard to say; it’s likely just a legacy issue. Before the outbox/inbox module NIP was introduced, most Nostr clients stored relay configs in kind3, but this isn’t the standard approach.

The implementation principle is to send a gift-wrapped note to a list of npubs, allowing only those npubs on the list to decrypt and view the note. However, it’s difficult to prevent npubs from replying to your note.
But yes, maybe other solutions can be implemented in the future. It’s a very interesting experiment.

0xChat uses WebRTC for audio/video calls. One difference from Signal/Telegram solution is that we use NIP-100 for signaling and also support custom ICE servers.

These are two different lists, meaning your follow list will not affect your contact list, and your contact list will not affect your follow list. In 0xChat moments, you have the option to view the feed of your contact list, but this option is not available in other clients.
Both the contact list and the follow list will sync to your relays. The difference is that the contact list is encrypted.

0xchat is primarily a DM app, but it also has a moment feature, so it can receive notifications for likes and zaps as well. If you don't want to receive these notifications, you can turn them off in Settings - Notifications.

Only clients such as Amethyst, Coracle, Nostrmo, etc., that support NIP-17 DMs, can receive messages sent from 0xChat.
Also we recommend using NIP-17 DMs instead of NIP-04 DMs, as NIP-17 helps hide your metadata, enhancing your privacy.

2024-08-23 00:21:10

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 15:44:52

- 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.

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.
