Marmot combines the MLS (Messaging Layer Service) Protocol with Nostr’s decentralized network to provide private group messaging without relying on centralized servers or legacy identity systems. MDK is the Marmot Development Kit and consists of four crates. White Noise is the Rust backend of the Flutter application, and the whitenoise crate uses the MDK library to implement all components required for a messenger application. This audit focuses on the MDK library.
