0xchat is a secure messaging client for Nostr focused on private, end-to-end encrypted conversations. Unlike clients that still rely on legacy NIP-04 DMs, 0xchat is built around the modern encrypted-messaging stack — NIP-44 encryption with NIP-59 gift wrap — which conceals message metadata as well as content.
Key Features
- Modern encrypted DMs: NIP-17/44/59 gift-wrapped private messaging
- Group chats: relay-based and private groups
- Lightning: zaps and ecash support
- Cross-platform: iOS, Android, and desktop (macOS/Windows/Linux)
Why Choose 0xchat?
If your priority is private messaging rather than a public feed, 0xchat is the closest thing Nostr has to a Signal-style experience. It is funded by OpenSats and actively developed.
Not to be confused with X’s (Twitter’s) “XChat”.
