The Lightning Network is a 'layer 2' protocol that operates on top of Bitcoin's blockchain; it enables fast bitcoin deposits to your Bitaroo Account.
To deposit bitcoin via the Lightning Network:
1. Go to Account --> Deposit
2. Switch Lightning to 'On'
3. Enter desired deposit amount
4. Click 'Generate Invoice'
5. Scan the QR code or copy the code string to your Lightning Wallet to pay the invoice.
Once paid, the amount should appear in your balance almost instantly.
Please note: users can generate only one invoice at a time but once paid they can generate a new invoice. There is no limit to total amount of invoices.
