Lightning Piggy

An electronic cash piggy bank for children that accepts bitcoin sent over lightning, while displaying the amount saved in satoshis.

LightingPiggy is an electronic cash piggy bank for children, that accepts Bitcoin sent over the Lightning Network. It displays payment amounts, messages, and the total satoshis saved. Our vision is to make bitcoin the savings’ standard for every child, while creating an educational platform to inspire future generations, not only to save in bitcoin, but also to learn to code and build in a free and open-source way.

Together, let’s make 2026 the year sats become the savings standard for every child - one piggy at a time ⚡️🐽

Christmas has come early 🎄 Huge thanks to the @LNbits community for making it even easier to configure LightningPiggy 2.0 with LNbits. With LNbits v1.4, the server name is now viewable as an optional QR. That means configuring LightningPiggy 2.0 with LNbits as its wallet now requires just two QR codes to scan. And the entire setup can be done on a mobile phone. We’d like to take this opportunity to thank everyone who has supported the project along the way. It’s been humbling to see the excitement and joy on kids’ faces (young and old!) receiving zaps on their piggies. We’re excited about what’s ahead and can’t wait to build, ship, and share even more in the year to come. Wishing you and your loved ones a very Merry Christmas! Let’s make sats the savings standard for every child ⚡🐽 Team LightingPiggy
