--- layout: static_page title: CLI Wallet/Daemon Isolation with Qubes + Whonix --- With [Qubes](https://qubes-os.org) + [Whonix](https://whonix.org) 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](https://torproject.org). 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](https://www.qubes-os.org/doc/qrexec3/). 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. ## 1. [Create Whonix AppVMs](https://www.whonix.org/wiki/Qubes/Install): + 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 `none`. - 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`. ## 2. In the AppVM `monerod-ws`: + Download, verify, and install Monero software. ``` user@host:~$ curl -O "https://downloads.getmonero.org/cli/monero-linux-x64-v0.11.1.0.tar.bz2" -O "https://getmonero.org/downloads/hashes.txt" user@host:~$ gpg --recv-keys BDA6BD7042B721C467A9759D7455C5E3C0CDCEB9 user@host:~$ gpg --verify hashes.txt gpg: Signature made Wed 01 Nov 2017 10:01:41 AM UTC gpg: using RSA key 0x55432DF31CCD4FCD gpg: Good signature from "Riccardo Spagni " [unknown] gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.
