The team behind Spark has spent years building on Bitcoin. After countless iterations, Spark represents our best attempt at creating the definitive platform for builders on Bitcoin. We built it from scratch, with strong opinions on what makes a truly great developer experience. Spark exposes powerful, low-level features for a wide range of use cases.
