VoidSend vs Tusile

VoidSend is a zero-knowledge encrypted messenger built for a post-quantum world. Every message, file, and call is encrypted on your device before it ever leaves — our servers act as a blind relay, mathematically unable to decrypt your data. ZERO-KNOWLEDGE ARCHITECTURE Unlike other messengers that promise privacy, VoidSend's Blind Relay design means the server only ever sees encrypted blobs. No plaintext. No metadata leaks. Your encryption keys never leave your device. POST-QUANTUM ENCRYPTION VoidSend uses hybrid encryption combining X25519 with ML-KEM-768 (Kyber), protecting your conversations against both today's threats and tomorrow's quantum computers. Messages are sealed with AES-256-GCM, and identities are verified with ML-DSA-65 post-quantum signatures. MESSAGING • End-to-end encrypted direct and group messages • Disappearing messages (5 seconds to 7 days) • Encrypted file sharing with automatic 24-hour server-side deletion • Emoji reactions, replies, and typing indicators • Message search across your conversation history VOICE & VIDEO CALLS • Peer-to-peer WebRTC audio and video calls • Optional post-quantum encrypted media streams • Call history WEB3 PAYMENTS (Only available on www.voidsend.xyz) • Built-in multi-chain wallet: Ethereum, Base, and Solana • Send and receive ETH, USDC, USDT, SOL, and SPL tokens • Wallet derived from your encryption seed — one identity, one key PASSWORDLESS AUTHENTICATION • Sign in with your crypto wallet (EIP-712 signature) • Or use Face ID / Touch ID with Passkeys • No email. No phone number. No passwords. Just you. STORIES & PROFILES • Share ephemeral photos and videos with your contacts • Custom avatars and usernames • Online status visible only to mutual contacts PRIVACY BY DESIGN • No data collection beyond your username and encrypted data • Block contacts and control who can message you • Cross-platform: your encrypted identity syncs seamlessly across all your devices VoidSend doesn't ask you to trust us — it's built so you don't have to.
