Private messaging on Nostr, inspired by Signal.

• End-to-End Encrypted: Military-grade NIP-44 encryption ensures only you and your contacts can read messages
• Metadata Private: Gift-wrapped messages (NIP-17) hide sender identity and timestamps from relays
• Decentralized: No central servers. Your keys, your data, your freedom
• Real-time: Instant message delivery with WebSocket subscriptions
• Offline-First: Messages cached locally with IndexedDB for instant loading
• File Sharing: Send encrypted files and images via Blossom servers

• React 18 with TypeScript
• Nostr Protocol (NIP-04 & NIP-17 for messaging)
• Nostrify for Nostr integration
• TailwindCSS for styling
• shadcn/ui for beautiful components
• Vite for fast builds

• Node.js 18+
• npm or yarn

Doduo uses NIP-17 for maximum privacy:

• NIP-44 Encryption: Modern authenticated encryption for message content
• Gift Wrapping: Messages are wrapped in ephemeral keys to hide sender identity
• Randomized Timestamps: Send times are randomized ±2 days to prevent timing analysis
• Local Encryption: Messages stored locally are encrypted with your NIP-44 key

• NIP-04: Legacy encrypted direct messages (backwards compatibility)
• NIP-17: Modern private messages with gift wrapping (default)
• NIP-44: Authenticated encryption
• NIP-59: Gift wrap events for metadata privacy
