# Metadata-less Signing

Using Polkadot Vault v7.0.0 and higher, you can sign transactions on any network without needing to add the network’s metadata to your Polkadot Vault device. This functionality must be supported by the wallet you are using, and is available in Nova Wallet. You need to still add the chain specs for the chain that you wish to use: [Update Chain Specs in Polkadot Vault](/nova-wallet-wiki/wallet-management/hardware-wallets/polkadot-vault/update-chain-specs-in-polkadot-vault.md)

1. `Ensure` that you have added the chain spec for the chain that you wish to interact with.
2. `Ensure` that you have added the correct account with **the correct derivation path** to your Nova Wallet.

4. Create the transaction on your Nova Wallet device.
5. \`\`Select\`\` Continue, and then review the contextual information and select Confirm on your Nova Wallet device.
6. A QR code will now appear on your Nova Wallet device. You will see 2 QR codes. The “New (Vault v7+)” QR code is an animated QR code that allows you to sign transactions without updating or adding the chain’s metadata.
7. On your Polkadot Vault device, `select` the QR code scanner.
8. `Scan` the QR code with your Polkadot Vault device and then review the transaction details and sign the transaction.
