Private messenger with no phone number, no email, no SIM. New: Shielded Permanence™. Messages live permanently on the BitcoinZ blockchain and stay unreadable thanks to zk-SNARKs. The proof a message exists is public. Everything else is invisible. One 24-word seed runs 5 tools: messenger, BTCZ wallet, password manager, Channels and disposable identities. Stealth mode hides the app behind a calculator. Quantum-resistant key exchange (ML-KEM-768). Android, macOS, Windows, Linux.

The world's first ZkSNARKs shielded messenger built on BitcoinZ. No phone number required. Decentralized, zero-knowledge-protected messaging — your keys, your freedom.
