Since this week I'm a new (and only active) maintainer of nostr-php.
@swentel is the original author but he does not have the time to maintain the repo as he focused on other stuff. See this issue https://github.com/swentel/nostr-php/issues/32
In absence of responses since June, I applied. The main reason is because I'm using the library for developing some Drupal modules and found some small issues. I don't have much expierence with this new role. I'm also not very expierenced with Github, I like Gitlab more. I'm looking for other PHP developers to help / mentor me with this responsibility.
Check out the project on Github and you can also find a link to the Telegram group in the readme to catch up.
