Thank you for this great extension, especially in light of the latest security vulnerability 👍🏻
BTW, just a very minor cosmetic issue, the description for this extension in the admin panel is "Transfer money to other users through post rewards".
P.S. I got Flarum Boot Error after I enabled the extension and tried to open the forum. However on subsequent attempts it's OK. Here's the log:

P.P.S. I'm not a PHP guy but a search on the Internet shows that this error might have been due to a temporary MySQL service unavailability. I actually had opened the SQL admin on my hosting to remove the API key (because I'm not using it at all, just tested some stuff in the past) and also removed an unused database and it's possible that the hosting restarted the SQL service or something. The error has not appeared again and is probably not related to this extension.
