Lightning Piggy: STEMM Learning Powered by Sats!
Kids - Teens - Families | Building, Saving, Having Fun

Picture a modern 'saving jar' that lights up your kid’s eyes with every sat they save (sats: small units of bitcoin). Lightning Piggy isn’t just a cool gadget, it's a unique tool to turn your kids' efforts into an exciting adventure. It’s a hands-on way to explore Bitcoin through the Lightning Network (LN) and a perfect chance to build something together.
LightningPiggy is bringing the adoption of bitcoin to young people in a real and meaningful way. Our vision is to make sats the savings standard for every child.
Recognizing a job well done? Oink oink, sats! You-rock moments or we made it together? Oink oink, sats! Birthdays or Christmas? Oink oink, sats! Options are plenty, and all this helps kids / teens / entire families not just save for the future but also learn by doing.
What It Brings to Your Home:
- This isn’t just about money (no matter how great it sounds)—it’s about learning how to earn, budget, and take responsibility for your own savings stack.
- Building the piggy is a STEM playground (Science, Technology, Engineering, Mathematics and Money). Kids tinker with circuits, dabble in code, and turn into mini-inventors while you cheer them on (and maybe sneak in some fun yourself).
- The crew is small but keeps the project solid (regural software updates and real-world workshops). By building your own piggy, you’re supporting their mission. Freedom-tech with the open-source heart.
No Tech Guru Needed.
Lightning Piggy is open-source and easy to set up with a web installer (connecting to your wallet using tools like LNbits or Nostr Wallet Connect). Where you place your tech is up to the imagination. Paper cut shapes, 3D-printed items, an old toy, Lego? Just check all creative cases available on their website.

How about the usage?
Nothing to worry about.
Kids can receive sats with a quick scan of the QR code visible on the piggy. Easy. To refresh the status, shake the piggy and, voilà, newly collected funds display in seconds (⚡️🐽 fun!). Want to send sats back? Log into your LNbits to pay a Lightning invoice or move to a Bitcoin address.
BONUS: You can also set a personalized wallet-address (like 'name@lightningpiggy(.)com' ) to accept LN payments from anywhere in the world. Sure, you could carry your piggy to different places around, but for safety, it’s probably better to keep it at home.
📺 See how Nini (from RO₿OTECHY) managed with setting up her Lightning Piggy and receiving new sats. 👇 FYI, at the time of the recording, she was probably around 9. If she could do it, we all can.
Oink oink! To the world with sound money, curiosity, and creativity. To critical thinkers and explorers. To the #SovereignGeneration!
