yup, see what you mean. Hopefully my answer is not disappointing. It is to my knowledge not existant. I’d reason this way:
I don’t think it’s the application, which should secure the network layer. Vice versa is the way to go on (layered approach). Create a secure network layer, and run the app on top of it. Otherwise all apps would build their own security layer, and I doubt there are enough security specialists…
The layers of the underlying OS allows to achieve security.
A very secure ‘remote wallet’ GUI:
define secure 🙂 Well, why not tunnel X over a VPN or through ssh?
A bitcoind full node GUI manager:
is the same.
A wallet manager application:
again, security built into the app is against principle of layers. You can tell your full node, from which IP to connect.
