Spark was introduced by Lightspark in October 2024 as a payments-focused, scalable, Lightning-compatible protocol with native stablecoin support. Per Axios, Lightspark built Spark to allow token issuance and application development in a trust-minimized way, relying on Bitcoin for its underlying security guarantees. Spark is natively interoperable with the Lightning Network and requires no nodes or channels for integration, while also supporting offline receive. Transfers within Spark are fee-free, with users paying Bitcoin network fees only at the point of deposit or withdrawal.
Spark provides an Issuer SDK that lets developers create, mint, burn, freeze, and manage tokens, including stablecoins, directly on Bitcoin. Its native token standard, BTKN, defines how assets are issued on the network. The public codebase is available under the buildonspark/spark repository on GitHub. Spark is backed by a16z crypto, Paradigm, Ribbit Capital, Coatue, Thrive Capital, Felix Capital, Matrix, and Zeev Ventures. Spark has established affiliations with Tether, Brale, Xverse, Privy, Breez, and Flashnet. Spark has been mentioned by 125 accounts, with 375 total mentions.
