After opening the VPN client app, click the "+" button at the right end of the screen to begin adding your M-Key.
Add M-Key:
A new UI will appear labeled "Add M-Key."
Paste Your M-Key
You’ll see a text input box with a "Paste" button next to it. Click the "Paste" button to insert the M-Key (starting with m-key://) that you copied earlier.
Connect and Complete:
Once the M-Key is pasted, click the "Connect" button to establish your VPN connection.
Monitor Connection:
Check Bandwidth Allowance: The M-Key comes with a limited data allowance (GB). If you notice the connection slowing down, you may have reached the limit. To verify, go to the MetaMask Dashboard and check your current GB allowance. In the MetaMask Client Application, check the traffic usage and confirm if it matches the allowance shown in the MetaMask Dashboard.
Remove and Generate a New M-Key:
If your GB allowance has been exhausted, click the Delete Icon next to the M-Key to remove it from the app. Follow the steps in the How to Generate a New M-Key section to create and add a new M-Key.
