Hi can you give me instructions for the masternode?
If you have set up any masternode in the past, it shouldn't be a problem as steps are the same for almost all masternodes regardless of a coin.
You won't believe it but I've never done a masternode

Hehe, yeah, then you definitely need a guide.

I would suggest to go to their discord and ask for help. If they can't release a source code for a wallet, maybe they can at least make a mn guide.
