The Arduino nostr library that I'm working on at the moment is very nearly ready for release. Should be a day or two at most.

Featuring:

+ Basic relay management

+ Subscribe to events of kind 1 or 4

+ Broadcast events of kind 1 (notes)

+ Encrypt and broadcast events of kind 4 (encrypted DMs)

+ Receive and decrypt events of kind 4 (encrypted DMs)

nostr IoT all the things!
