Yes! UxU is a File Hosting service, but not in it's traditional sense. There is no Upload Button. You need to move to the cultured way of doing it -- using curl.
curl -X POST https://uxu.veradec.xyz -F "file=@file.png"
and the reponse will be a link with your Filename (sanitized ofcourse)
https://uxu.veradec.xyz/{random_string}/file.png
something of this sorts and you can share the link too!
