Everything You Need for Private Communication
Qu-Chat combines cutting-edge cryptography, decentralized technology, and user-friendly design to give you complete control over your conversations.
Core Features
Quantum-Resistant Encryption
Protected with NIST-approved ML-KEM-768 (Kyber) cryptography. Your messages are safe against both classical and quantum computer attacks.
Fully Decentralized
No central servers. Your messages are stored across a peer-to-peer network using P2P Framework—impossible to shut down or censor.
Web3 Identity
Connect with your Web3 wallet. No phone numbers, no email addresses, no personal information required. Your wallet is your identity.
True End-to-End Encryption
Messages encrypted on your device, decrypted only by the recipient. Not even we can read your conversations.
Secure Group Chats
Create encrypted group conversations with role-based access control. Only group members can read messages.
Decentralized Media Storage
Share images and files stored on IPFS—a distributed storage network that ensures your media is always available.
Zero Data Collection
We don't collect, store, or sell your data. We literally can't—there are no central databases to store it in.
Works Everywhere
Access Qu-Chat from any modern web browser. No app installation required, works on desktop and mobile.
Security Features
✓AES-256-GCM Encryption
Military-grade symmetric encryption for message content with authenticated encryption to prevent tampering.
✓ML-KEM-768 Key Exchange
NIST-standardized post-quantum key encapsulation for secure key exchange resistant to quantum attacks.
✓Client-Side Encryption
All encryption happens on your device. Plaintext messages never leave your browser.
✓No Backdoors
NIST-standardized algorithms with no proprietary modifications. We use proven cryptographic protocols exactly as designed—no hidden backdoors.
✓Tamper Detection
GCM authentication tags ensure messages haven't been modified in transit. Any tampering is immediately detected.
✓Censorship Resistant
Peer-to-peer architecture makes blocking or censoring Qu-Chat virtually impossible—no single point of control.
Privacy Features
Anonymous Sign-In
No phone number, no email, no personal info. Just connect your wallet.
Zero Metadata Logging
We don't track who you talk to, when you talk, or how often.
Your Keys, Your Data
Private keys stay on your device. Only you control access to your messages.
