Add networks in Polkadot Vault

Polkadot Vault supports 3 networks by default: 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 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!
