LUME

What is LUME?

LUME is an anonymous, end-to-end encrypted messaging system where the server acts as a blind relay. It stores and forwards opaque encrypted payloads without access to plaintext or keys. Your identity is an Ed25519 key pair derived from a BIP39 phrase, meaning no phone number or email is required. Messages use X3DH key agreement and a Double Ratchet. The source code is available for viewing and auditing under a strict license.
