Arcade v0.1.0-beta: Nostr Chat MVP

Arcade (formerly Arc) is a free and open source Nostr chat and commerce app built for Android and iOS.

No Bullshit Bitcoin is funded by our community. Click here to support us.

"Today we launch our first Arcade beta build for Android and iOS, featuring three kinds of Nostr-based chat:

- Public channels (NIP-28)
- Encrypted direct messages (NIP-4)
- Encrypted private channels (NIP-112)."
"Combining Nostr chat with with Nostr-based user authentication (NIP-06) and followers & contact management, the Arcade app is now the first cross-platform mobile app intended to be a drop-in replacement for Telegram and other popular chat apps."
"You'll notice our app has no proprietary back-end: only Nostr relays. This enables truly unstoppable chat, as our chat channels can be accessed by any Nostr clients."
"A lot of work remains to get Arcade to the level of polish of the major chat apps. This will be heavily work in progress over the next few months as we proceed toward a stable release we can put into the app stores."
"We hope you'll help us by downloading this beta build and telling us how we can improve the app so you'll feel comfortable using it regularly. Please post any feedback in the "Arcade Feedback" channel, tweet at us @TheArcadeApp, or file an issue on our GitHub. Thank you!"
