About this app
VoidSend is a zero-knowledge encrypted messaging app designed for privacy-first communication.
Every message, file, and call is protected with end-to-end encryption using a hybrid cryptographic system that combines classical (AES-256-GCM, X25519) and post-quantum (ML-KEM-768, ML-DSA-65) algorithms — keeping your data safe today and against future quantum threats.
Features:
- End-to-end encrypted text messaging
- Encrypted file sharing with hybrid key encapsulation
- Secure voice and video calls via WebRTC
- Passkey authentication — no passwords required
- Web3 wallet integration (Ethereum and Solana)
- Zero-knowledge architecture — we cannot read your messages
- Open cryptographic standards (NIST FIPS 203, FIPS 204)
Your keys never leave your device. VoidSend stores only encrypted data — no plaintext content, no IP addresses, no tracking.

What’s new
What's new?
• Opening the app without a connection now shows your chats instead of the login screen.
• Tapping a notification opens the existing conversation .
• Your chat history now stays on the device after logging out and is restored when you sign back in. It is wiped only if a different account signs in.
• Login is passkey-only. Wallet-signature sign-in has been removed.
• Faster, safer face-blur: the model now ships inside the app instead of loading from a third-party CDN.
