A watch-only wallet allows you to track your bitcoin wallet without plugging in your BitBox02 every time. To do this, you can simply export your extended public key and import it into another app. This gives you the ability to see the balances and transactions of all of your addresses without being able to make transactions.

What is an extended public key (xpub)?

An extended public key allows you to create addresses belonging to your wallet. It does not allow you to send transactions or sign messages. This means you can track your wallet balances without the risk of losing your money.

If you share your xpub with somebody else, they will be able to see how much Bitcoin you hold in that wallet.

Addresses that are created within the watch-only wallet should not be trusted, as they could be altered by a third party, if the app or your device is compromised. While for smaller amounts you might want to take the risk, you should only trust addresses shown on your BitBox02 display.

Getting the extended public key

First, open the BitBoxApp and chose the Bitcoin account you want to track.

Next, click on "Account info" in the top right corner.

There you will find the extended public key. Copy it.

Importing the extended public key

In this example we use BlueWallet to import the xpub to create a watch-only wallet on our phone. You can use any wallet that supports importing xpubs.

In BlueWallet, under "Add a wallet" we chose "Add now".

On the following screen, we choose "Import Wallet" and enter the xpub we have copied earlier from the BitBoxApp or simply scan the QR-Code that is shown right next to it.

The wallet is imported successfully and will be shown in the overview.

Clicking on it should show the entire transaction history of the wallet.

Now you can track the transactions and wallet balances of your BitBox02 wallet on your phone without the risk of losing your bitcoins!


What is a watch-only wallet?
A watch-only wallet is a wallet that only lets you view and create addresses. It does not give you the permission to send the coins in that wallet. You can think of it as a "view-access"-key to another wallet.

How to create a watch-only wallet?
You can create a watch-only wallet by exporting the extended public key of your wallet. Most wallet-apps will let you do this within the account information tab.

Can a watch-only wallet send transactions?
No, a watch-only wallet can only create addresses. It cannot send transactions.

Is a watch-only wallet safe?
Yes, you do not risk your funds if you use a watch-only wallet. You should not trust the addresses that are created by the wallet though, as they have not been confirmed independently on your hardware-wallet and could be replaced by a third party.
