Marmot-TSPrivacy-preserving group messaging

End-to-end encrypted group chat with MLS and Nostr

End-to-End Encrypted

Built on MLS (RFC 9420) for group messaging security with forward secrecy and post-compromise security

Uses Nostr relays for message distribution - no central server required, censorship-resistant

Ephemeral signing keys and gift-wrapped welcome messages protect metadata and provide unlinkability

Comprehensive TypeScript support with generic types for flexible, extensible implementations

Bring your own storage, network layer, and history backends - works with any Nostr client library

Implements all Marmot Improvement Proposals (MIP-00 through MIP-03) for interoperability
