Creating a Watch-only Wallet with xPub and Address Explorer in Vault12

Vault12 introduces a new feature that reduces your security risk by enabling you to create a Watch-only wallet for assets in your digital Vault. No need to expose seed phrases nor unlock assets.


Watch-only wallets enable you to keep track of your cryptocurrency balances without ever exposing your private keys or your seed phrase. Vault12 has introduced a new capability, Address Explorer, for BIP39 compatible wallets that enables you to display your wallet addresses for assets locked in your Vault - without the need to unlock assets.

These addresses can then be used in Watch-only wallets. The Address Explorer handily enables you to copy addresses for easy import and also provides an xPub export to make it very simple and straightforward to create Watch-only wallets.

What is an xPub

xPub, an extended public key, is a special public key that represents a group of public keys or addresses. xPub is used to create a Watch-only wallet, a simple way to track your balances and transactions without using your seed phrase or your actual transactional wallet.

Wallets that use the BIP39 standard provide multiple addresses (often referred to as accounts) that can be used to deposit cryptocurrency. To protect your privacy even further it is advisable to use different addresses, and not just the default first address. In fact, the BIP32 standard for Hierarchical Deterministic Wallets gives you even more control over selectively revealing addresses, protecting your overall privacy.

Benefits 

Each BIP39 wallet provides public addresses that can be used for different assets e.g. different cryptocurrencies or NFTs. Many wallets refer to these addresses as Accounts, but as far as the blockchain is concerned these are addresses where digital assets can be deposited. Addresses give you the following benefits:

  • Multiple addresses mean multiple currencies in a. single wallet, protected by a single seed phrase
  • The ability to have a virtually unlimited number of crypto addresses for receiving purposes, while keeping your seed protected.
  • As an added protection, you can avoid using the first several addresses to further reduce your risk of compromise.
  • Using your addresses, or doing an xPub export means you can inspect your balances without ever exposing your seed.
