Step 1: Get a Lightning Network-enabled Bitcoin wallet:
First, you'll need a Bitcoin wallet that lets you receive, hold, and spend Bitcoin via the Lightning Network.
Step 2: Buy Bitcoin and fund your Lightning Network wallet
If you don't have bitcoin in your wallet yet, you'll need to buy some. Every country and region is different, so you'll want to do some research before choosing an exchange.
Step 3: Make a payment
Open your wallet
Scan the OpenNode QR code or tap on the “Open in wallet" button.
Confirm everything is correct and proceed with payment
