KeepKey is the premier hardware wallet for the ShapeShift platform. It natively integrates with ShapeShift and receives regular firmware updates from them to maintain compatibility with their platform. Generally, this hardware wallet will come with a card. Write your wallet words on it (Your private key’s back-up), and store them somewhere safe like in a safety-deposit box or a safe on your premise. You won’t want to lose these wallet words, as they are necessary if you need to re-gain access to your funds, or initialize a new device with your key.
