A peer-to-peer messenger with end-to-end encryption. Messages and calls travel directly between devices, and the traffic itself is shaped so that from the outside it doesn't stand out from ordinary video.
Closed alphaDevices connect directly. The infrastructure only helps them find each other — it cannot read a conversation or reconstruct who talks to whom.
Ed25519 for signatures, X25519 for key agreement, ChaCha20-Poly1305 and AES-GCM for content. Private keys are never transmitted anywhere.
An encrypted envelope waits for the recipient and is delivered once they come back online. The server holds it without being able to open it.
Three independent modules. All cryptography and networking live in the C++ core; the interface only talks to it.
A five-layer engine: encryption, QUIC transport, mesh routing. Runs entirely in memory and never writes to disk.
Helps devices behind NAT find each other and queues messages for offline recipients. Keeps no state about users.
Desktop application: chats, calls, history. Owns on-device storage — the core does none of it.
How the protocol works in detail → — the threat model, what the relay can and cannot see, and how the engine can be licensed into another product.
The source code is proprietary. Alpha builds are distributed under a separate agreement; third-party components and their licences are documented.
