Privacy-first, Matrix-native communication — built from scratch in Rust.

Vauxl is a Matrix homeserver and client written from scratch in Rust. It federates natively with the entire Matrix network (Element, FluffyChat, Cinny, etc.) while adding an asymmetric security layer — Vauxl Secure Mode — that activates automatically when both endpoints are Vauxl clients:

• CRYSTALS-Kyber-1024 post-quantum key encapsulation (X-Wing hybrid KEM)
• Sealed sender — server cannot correlate message sender to MXID
• Double Ratchet+ — per-message forward secrecy beyond Megolm epochs
• Zero-knowledge relay — homeserver stores only opaque ciphertext

When talking to a standard Matrix client, Vauxl degrades gracefully to Megolm E2EE. No configuration. No broken compatibility.
