First post here...As you may know, Electrum-VTC currently does not have ARM support. After a few aggravating errors, i finally was able to successfully compile Electrum-VTC on a Pi Zero running Raspbian Stretch. The Pi is also configured as a USB dongle for local SSH/XRDP and can be set up with zero internet access if desired.
I plan to do a full writeup for the whole setup in case others were wanting the same. I just wanted to show it off a little bit until then.
