As mentioned in the instance sidebar, there's a Matrix homeserver at genzedong.xyz and a related space for /c/genzedong@lemmygrad.ml. More details here.

Looks like details can be found here:

I don't think the association is official, but there's genzedong.xyz. It's run by a lemmygrad user and has a lot of lemmygrad users on it.

I think there was a matrix server at one point but it was shut down bc its too insecure
