Update network metadata

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.

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!
