# Add networks to 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](https://metadata.novasama.io/#/polkadot). 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.
{% hint style="info" %} 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.* ![](https://docs.subwallet.app/~gitbook/image?url=https%3A%2F%2F631687399-files.gitbook.io%2F%7E%2Ffiles%2Fv0%2Fb%2Fgitbook-x-prod.appspot.com%2Fo%2Fspaces%252F-Lh39Kwxa1xxZM9WX_Bs%252Fuploads%252FRwaRPv03X8VV0wWJXHXu%252Fimage.png%3Falt%3Dmedia%26token%3D7e3aca7e-c0fe-4eed-b483-af1e2dbf4834\&width=300\&dpr=4\&quality=100\&sign=eafa51e0\&sv=2) {% endhint %} 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 it, 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!
