Decentralized messenger with post-quantum security, self-custodial wallet, and Mini Apps.
No sign-up. No tracking. No compromises.
Spixi is a privacy-first super app for secure messaging, crypto payments, and in-app extensions. Built for people who value freedom, privacy, and control.
Why Spixi?
- No Personal Info Needed
No phone numbers, emails, or accounts. Just install and start chatting.
- True End-to-End Encryption
Chats, calls, and files are dual-encrypted with unique keys per contact. Keys never leave your device - only you and your contact can read your messages.
- Post-Quantum Protection (PQC)
Hybrid key exchange (RSA + ECDH + Kyber/ML-KEM) safeguards your data against both today’s and tomorrow’s quantum threats.
- Self-Authentication
Your cryptographic address is your identity. You sign your own messages - no servers to trust, no third parties to validate you.
- Secure File Sharing
Send files directly, without cloud storage or hidden access points.
- Built-In Self-Custodial Wallet
Send and receive IXI cryptocurrency instantly, right inside your chat.
- Mini Apps (dApps)
Extend Spixi with built-in apps - tools, games, workflows, and more.
- Decentralized
Runs on the Ixian Platform. No central servers, no single point of control.
Spixi is open source, and designed for people who value freedom and digital sovereignty.
