Yeah, the website is quite useless for that purpose. I see that they added a timeline on the top. Maybe you can follow it into the past to check the release notes to see if they mention which alts they included. They don't have a contact form, live chat or a support ticket. You might find more info on their Discord or reddit channels.

I was interested in trying the wallet due to some USDT I have on Tron, but they don't support that network at all. The only way to know for sure is to install the client and try to find and enable the assets from the list. If it doesn't work, they don't support it.
