The Frontier

Amethyst is re-implementing MLS and Marmot protocols and a new secp256k1 library in pure Kotlin, based on published test vectors, aiming for encrypted direct messaging and Schnorr signature support.

Nymchat reverted its Marmot protocol integration for NIP-17 group chats due to the lack of proper multi-device support, highlighting the importance of this feature for cross-platform clients.

Perser, a Nostr-native payments daemon and invoicing software, is integrating MDK for encrypted merchant-to-customer messaging, and adding Stripe and Square as payment providers, leveraging Marmot encryption.
