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.

Setting up pool payouts.

2. Click on “Connect wallet” in the pool payouts settings window. 

3.  Select the “MetaMask” method.

4MetaMask will open and suggest connecting the wallet to the website. Select the address and click “Continue” and then “Connect”. 

5. Go back to your account in the pool and select the necessary network in the payout settings window (let’s say BNB Chain).

6. When you select the network go back to MetaMask to confirm adding the network to the MetaMask and confirm changes to the network. 


7. Set up your min. payout limit (min acceptable value is 0.005 ETH). If you selected BNB Chain you also need to set up Max. Gas Price for your payouts. If you select OKEx ChainHecoPolygon network you don’t need to set up Max Gas Price as we pay for transaction fees, it is free for you. When you fill in all the parameters click on “Continue”.

This is how transaction fee mechanism works in BNB Chain и Arbitrum: 
Pool freezes a part of your income to pay for transaction fees, then we send out your payout transaction to you, after the network confirmations, the pool recalculates the actual transaction fee and refunds the unused frozen funds to your account.

8. Open MetaMask to sign the changes to your payouts network. Please make sure you understand what you are signing!


Your payout settings are now completed.
