Wallet and DEX in one app (Desktop, Mobile, Web) that has VIA listed.
I don't think Viacoin is listed
It IS listed, though there are problems with the only known electrum server. Luckily somebody (not involved with VIA) decided to set up another one. Problem is that VIA is using lots of resources, mainly RAM... because the chain is long and has a short block time, so it also grows fast.
If there would be a community, eg on discord it would be much easier to coordinate such things and find people who are willing to run a server, eg the ones that hold a ton of VIA.
