In this example we use the already known blockchain.com (formerly blockchain.info ) online wallet.

At first you have to log in into the wallet. After you are on your dashboard, click on „Settings“ on the top right and then on „Wallets and addresses“ on the menu.

In the next step, select the wallet you want to use with Premium Black. In our case we take the first „My Bitcoin Wallet“ and select the „Manage“ option on the right.

Then we click on the „More options“ item and select „Show xPub“ from the menu.

In the following window we actually see the public key (starting with pub) that we need for the assistant. We copy this completely and then continue with the third step of the wizard setup.
