How to swap with Keystone

On Shieldz, choose Connect, then Keystone, and scan the account QR code your Keystone shows. The device never connects by cable or Bluetooth.
Pick the coin you have and the coin you want, enter an amount and paste the address you want to receive at.
Scan the transaction QR code Shieldz shows with your Keystone, then check and approve it on the device.
Show the signed QR code back to your camera. Shieldz broadcasts it and tracks the swap until it lands.
