Polkadot Vault is a cold storage solution that turns your iOS or Android device into a dedicated hardware wallet for Substrate-based and EVM networks. Your keys are kept secure (i.e. offline) at all times, and transactions are signed in an air-gapped way via QR codes.
We advise you to create a backup of your recovery phrase and update to the latest version of Polkadot Vault if you are utilizing Parity Signer (an older version of the app before its rebranding).
Polkadot Vault supports 3 chains out of the box: Polkadot, Kusama, and Westend. To add more networks, you can scan a trusted spec QR code and metadata QR fountain. Below are the detailed instructions:
Step 1: Navigate to the Novasama Metadata Portal. The interface should be like the image below.
This should be done on a device that is not your Polkadot Vault device (PC recommended).
Step 2: Choose the network you want to add in the Network tab on the sidebar.
To make it easier, type the network you want to update in the Search bar.
In this case, we want to add the Avail network.
You will see a QR code which will be used to add the corresponding network to your account.
Step 3: Open the Polkadot Vault app and click on the Scan QR code button at the bottom of the screen.
Step 4: Scan the QR code provided in Step 2 to add the network. Once you've completed, review the verifier certificate and select "Approve".
Step 5: After approving the addition of the new network, you'll be prompted to create a new key (account) for that network. It will be added to the main tab under the selected key set.
Step 6: You have successfully added the network!
Given that your Polkadot Vault device is always offline and separated from any networks (air-gapped), you'll need to engage in a specific process to ensure your transactions remain valid by updating the chain metadata.
This can be done through the use of QR codes found on the Novasama Metadata Portal, which will provide your device with the information required to update the chain metadata.
To update the chain metadata, please follow the instructions below:
Please look at the following example for your perusal. Here, we are updating the metadata of the Avail network.
Step 1: Navigate to the Novasama Metadata Portal. The interface should be like the image below.
This should be done on a device that is not your Polkadot Vault device (PC recommended).
In this case, we are using a PC.
Step 2: Choose the network you need to update in the Network tab on the sidebar.
To make it easier, type the network you want to update in the Search bar.
In this case, we want to update the Avail network metadata.
Step 3: Go to the "Metadata" tab.
Step 4: Scan the Metadata Animated QR code using your Polkadot Vault device.
Make sure your device remains stationary while the scanning process is in progress. This may take a few minutes to complete.
Step 5: Once you've completed, review the verifier certificate and select "Approve".
Now, you have successfully updated the network's metadata!
Step 1: Open your Polkadot Vault app and have the QR code ready.
Step 2: On the Avail Space homepage, click on the account name at the top right of the screen to access the account selection tab.
Step 3: In the account selection tab, click the "Attach account" button at the bottom left corner.
Step 4: Choose "Connect a Polkadot Vault account".
Step 5: Scan the QR code provided by the Polkadot Vault to continue by clicking the "Scan QR code" button.
Please note that you would need to permit Avail Space to use your camera to import it using a QR code.
If you have not yet granted this permission, Avail Space will show the following message:
Click the "Go to Setting" button. You will be directed to our security settings screen. Please switch the toggle and approve the browser pop-up to enable camera access.
Step 6: Put the Polkadot Vault app (with the QR code displayed) in front of your computer and scan it with the computer's camera.
Step 7: Once your computer recognizes the QR code, you will be redirected to the Avail Space homepage. Your account is now ready!
After your Polkadot Vault account has been successfully connected to Avail Space, you can click on the account name at the top right of your screen. You will notice the QR icon next to your linked account list (see the image below), as this is to differentiate it from accounts linked to other extensions and other account types.
In this case, most steps are identical to the instructions above; however, in Step 2, you need to click the "Attach an account" button and choose "Connect a Polkadot Vault account".
