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)

• 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.

What's new in 1.0.22
Privacy and security
• Stories are now end-to-end encrypted. Only the contacts you share with can open them. Contacts on an older version will be asked to update to see your stories.
• Every message, edit and attached file is now signed together with its sender and recipient, so it can't be redirected or swapped.
• Calls are checked against your contact's key, so no one in the middle can listen in.
• Your messages and sent media are no longer copied into iCloud or computer backups, which aren't end-to-end encrypted.
• Link previews come from the sender. Opening a chat no longer contacts the linked website.
• Adding a contact from a link now asks you first.
Calls
• Tap your small video to swap it with the big one, and drag it to any corner.
• Both people turning on their camera at the same time now works.
• Unanswered calls end on their own, and each call appears once in your history.
Reliability
• Messages sync more reliably, and ones that failed to arrive are retried.
• Messages you send while offline go out when you reconnect, and large files get more time to upload.
• Received photos and files stay available after the system clears space.
• Unread counts and read receipts stay correct across your devices.
• Tapping a notification opens the right chat.
• App Lock returns you to where you were, and Face ID no longer loops.
Fixes
• The back button stopped working after leaving a chat on iOS 27.
• Group chats load older messages smoothly and update in place.
• Deleted and expired messages leave nothing behind on your device.
You may be asked to sign in once after updating.
