With Qubes + Whonix you can have a Monero wallet that is without networking and running on a virtually isolated system from the Monero daemon which has all of its traffic forced over Tor.
Qubes gives the flexibility to easily create separate VMs for different purposes. First you will create a Whonix workstation for the wallet with no networking. Next, another Whonix workstation for the daemon which will use your Whonix gateway as it's NetVM. For communication between the wallet and daemon you can make use of Qubes qrexec.
This is safer than other approaches which route the wallets rpc over a Tor hidden service, or that use physical isolation but still have networking to connect to the daemon. In this way you don't need any network connection on the wallet, you preserve resources of the Tor network, and there is less latency.
Using a Whonix workstation template, create two workstations as follows:
The first workstation will be used for your wallet, it will referred to as
monero-wallet-ws. You will have
NetVM set to
The second workstation will be for the
monerod daemon, it will be referred to as
monerod-ws. You will have
NetVM set to the Whonix gateway
sys-whonix. Before moving on, make sure this workstation has enough private storage. You can estimate how much space you need by checking the size of the raw blockchain. Keep in mind that the blockchain will take up more space with time.
