Every message generates a real Barretenberg Honk zero-knowledge proof, permanently anchored on Solana. Your keys never leave your device.
How it works
Generate your keys
An X25519 keypair is created client-side and encrypted with your passphrase. Your private key never leaves your device.
Encrypt & Prove
Every message is encrypted with X25519-ECDH + XSalsa20-Poly1305 and a Barretenberg Honk ZK proof is generated automatically.
Anchor on Solana
The proof hash is submitted to a Solana Anchor program on devnet, creating a permanent, immutable, verifiable record.
ZK Proofs
Every message generates a real Barretenberg Honk zero-knowledge proof — cryptographic evidence of authenticity without revealing identity.
Sealed Sender
Send messages where even the server cannot determine who sent them. True sender anonymity using ephemeral X25519 key pairs.
Solana Anchoring
ZK proof hashes permanently anchored to Solana devnet via an Anchor program. Immutable, verifiable, decentralized on-chain.
Encrypted Groups
Multi-party encrypted group chats with per-message ZK proofs, file sharing, reactions, pinning, and disappearing messages.
