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.
