LOS ANGELES, April 29, 2025 (GLOBE NEWSWIRE) -- Today, Lightspark is launching Spark.
It started as a small experiment inside the Lightspark offices. But very quickly, it became the thing the team couldn’t stop thinking about. After years of building on Bitcoin and Lightning — trying everything and running into walls — Spark felt like a breakthrough. Once the team had their first internal MVP, they knew there was no turning back.
Now it’s real.
Spark is the fastest, cheapest, and most UX-friendly way to build financial apps and issue assets on Bitcoin.
It’s a high-speed payment and settlement stack for Bitcoin — a trust-minimized protocol that lets you move Bitcoin and Bitcoin-native assets, like stablecoins, instantly and at near-zero cost. All natively on Bitcoin, with no bridges or wrapping.
Built for developers
Spark is lightweight, efficient, and designed for developers who want to move fast without compromising Bitcoin’s core strengths.
The team has spent the last few months working with partners to design the best developer experience possible. Today, Lightspark is shipping two SDKs that hide all the messy parts — so you can just build.
With Spark, developers can:
It’s early
This is a beta. Things will break. Some parts will feel rough. You’ll hit limits the team already know about — and probably some the team don’t.
Spark is not finished. But it’s real enough, fast enough, and powerful enough that it’s worth your time to start building.
Lightspark will be moving fast, listening hard, and shipping relentlessly. Your feedback will help make Spark better.
