Welcome to Spark

Spark is bringing Bitcoin back to its roots: money.

It’s the Bitcoin money network — purpose-built for payments and settlement. With Spark, developers can move Bitcoin and any Bitcoin-native assets (including stablecoins) instantly, at near-zero cost, while staying fully connected to Bitcoin’s existing infrastructure.

We built Spark to be the most lightweight yet powerful toolkit for developers building money applications on Bitcoin. From the ground up, Spark was designed to overcome Bitcoin’s limitations—fees, UX, liquidity fragmentation, scalability. By natively integrating Bitcoin, Lightning, and tokens, Spark makes it possible to build efficient, scalable financial products on Bitcoin.

Spark wasn’t born out of theory. It was built from frustration. After years of running into bottlenecks, we built the protocol we wished had existed all along.
