Bitcoin is programmable money and despite the hard rules in the supply, verification and governance of the network, what you can do with the funds is pretty malleable once they are under your control. Not only that, but there are always new and interesting ways to broadcast to the bitcoin blockchain or its second layer solutions that have brought interesting use cases to the surface.

You can create payment links that request payments, or you can create payment links that have already hold funds ready to be claimed. You could create prepaid Lightning invoices and hand them out as gifts to friends and family, create reward options for your customers, encourage engagement on social media, or even create your own treasure hunt or a lightning-based airdrop.

The possibilities are only limited by your imagination. If you’d like to try creating prepaid lightning invoices, one of the simplest ways is to use Ln.Cash.

What is allows you to create secret links containing bitcoin on the Lightning network. You will fund the link with bitcoin first and receive a special LN-URL or QR code. Once a cash link has been created and paid for, a unique url is generated which can be shared with anyone who may claim it and receive bitcoin.

Claims can only be made once for the full amount, so whoever gets to it first gets to keep the funds.

Creating prepaid invoices

  1. Head over to the LN cash site
  2. Set the number of satoshis you want to store in the link
  3. Add a special message for the person who receives the funds
  4. Click create
  5. You will then receive a QR code and an LN-URL link; you can save either one or both and use them as you please

Note: It’s important to note that once you transfer these funds to this secret link, if you lose the link or QR code, you will no longer have access to those funds, so create these invoices with care and ensure you copy them down correctly and don’t place too much money in them.

Optional extras:

When you’re creating your LN-URL Withdrawl claims, you can include additional parameters for users to claim funds, like verifying their Twitter account and even asking users to follow a certain Twitter account as a condition.

How are links paid for or claimed?

Once you’ve created the funded invoice, you can claim immediately; there is no time delay. You can send it to a friend or family member, post it on social media and anyone who sees it first and claims the funds will receive it in their wallet.

To claim the funds, the user will need a Lightning-enabled bitcoin wallet to scan the QR code or paste the LN-URL presented on into their wallet of choice.

You can also write the LN-URL to an NFC device like a Bolt Card and transfer the funds to a bitcoin wallet that supports lightning and NFC; oh, and your device needs to support NFC too. So no sense in trying to claim using your desktop wallet unless you have an NFC reader connected.
