Hello, everyone! I am Cipher from JoyID. JoyID is a decentralized, non-custodial key management tool based on mobile FIDO/Passkey technology, integrating blockchain wallet and Nostr key management functionalities. It allows users to manage their keys without the need for passwords and mnemonic phrases. We recently added support for NIP-07 and are currently working on implementing support for related protocols like NIP-04. The product is currently in a testing environment.

The first Nostr client adopts JoyID is flycat, you can access it here: https://flycat.club/en/login (choose the 2nd connect option). Please give a try, and leave your comments. We would greatly appreciate your help in testing and providing your valuable feedback.

Thank you very much!
