This article provides a detailed guide on how you can effectively connect your OneKey Pro (an airgapped hardware wallet) to App wallets such as MetaMask, and how you can sign an transaction via QR codes.

Sign Transactions via QR Codes
OneKey Pro allows you to sign transactions via QR codes when connected to App wallets such as MetaMask. This process ensures that your transaction data never leaves the secure environment of your hardware wallet, providing an additional layer of security. Let's explore how you can do this:
- Initiate a transaction from your OneKey Pro address on your MetaMask mobile application.
- When you get to the Confirm screen, check the details of the transaction and press "Confirm".
- A QR code will appear on your MetaMask screen. This QR code contains the transaction data.
- Open your OneKey Pro and choose "Scan".
- A QR code scanner will open. Scan the QR code displayed on your MetaMask.
- Your OneKey Pro will decode the transaction data and display it for your review.
- If the transaction details are correct, press "Continue" and slide to sign the transaction on your OneKey Pro device.
- A new QR code will be generated on your OneKey Pro. This QR code contains the signed transaction data.
- Press the "Get Signature" button on your MetaMask and a QR code scanner will open.
- Scan the QR code generated on your OneKey Pro to complete the transaction.
AirGap Mode
AirGap Mode refers to a security measure where your OneKey Pro is completely isolated from other devices and networks. This isolation prevents any potential remote attacks trying to access your digital assets, disabling Bluetooth, USB, and NFC transfer function.
To enable AirGap Mode on your OneKey Pro, follow these steps:
- Unlock your OneKey Pro device and navigate to the "Settings" menu.
- Select "AirGap Mode" from the menu.
- Toggle on "Air Gap" to enable the AirGap Mode.
- You'll be asked to confirm your action. Tap on "Enable" to activate the AirGap Mode.
With the AirGap Mode enabled, your OneKey Pro operates independently, ensuring that your digital assets are stored in the most secure environment.
