We recommend Wallet of Satoshi because it is the easiest wallet to get started on the Bitcoin Lightning Network.
If you haven't installed it yet, you will need to install it first.

Next, open the Wallet of Satoshi app and press the Receive button.

On the Receive page, first make sure you are in the @ tab at the bottom.

Here you will find your wallet address as an email. This is what you will submit into your Crypto Tap app Dashboard Settings (gear icon top left).
