You can sign messages under the “File” menu. Simply select one of your nushares addresses and paste the json content in the field below.
BTW: Just recognized it still asks for a peercoin address should be fixed.
oh. very simple. tks a lot.
PS: nice catch.
It still asks for a peercoin address - it should be corrected to a NBT address, as soon as possible.
I added a ticket to the Nu repo to address this. The fix should be very straight-forward, and I expect it will be included in the next build.
