You can turn your old mobile phone into an AirGap hardware wallet. This works for any smartphone with Android OS 5.0 and higher and iOS 12 and higher.

The main advantage of AirGap is that you can connect it to MetaMask and use all the networks for the pool payouts, but still enjoy the safety of the hardware wallet when your private key is stored on your device.

To turn your old smartphone into a hardware wallet you need to:

  • Download the “AirGap Vault” app to your old smartphone from the app store or GitHub
  • Download the “AirGap Wallet” to your current smartphone to manage the wallet and send out transactions. It works similar to the Ledger app so we won’t be describing it here.

We recommend enabling the Flight mode on your newly created hardware wallet, so that it can’t communicate with the network. 

Also it’s a good idea to set up a low battery mode.
