Breez and Spark have collaborated to launch a new Breez SDK implementation based on Spark's Bitcoin-native Layer 2 infrastructure, simplifying the process for developers to integrate self-custodied Lightning payments into everyday applications and services. This SDK supports all major programming languages and frameworks, accommodates LNURL and Lightning Addresses, and enables real-time user interaction through mobile notifications. The Spark-based implementation offers a Bitcoin-native experience without relying on bridges or external consensus, suitable for various scenarios such as content streaming payments, social app monetization, in-game currency, cross-border remittances, and AI micropayments. Breez will act as a Spark service provider to support the development of the Spark ecosystem. The new SDK is expected to be released later this year, with technical specifications to be announced subsequently.

<h3>Breez + Spark — A New Way to Build on&nbsp;Bitcoin</h3>Breez and Spark are teaming up with a new Breez SDK implementation built on Spark’s Bitcoin-native Layer 2 infrastructure — making it even easier for developers to integrate self-custodial Lightning payments into everyday apps and services.<img src="https://static.sosovalue.com/sosovalue/2025/05/22/0c6ff47b-a6f3-4c77-9d8c-7e72d5842be0.jpg">Breez and Spark are joining forces with a new implementation of the Breez&nbsp;SDK.<a href="https://breez.technology/report">Bitcoin is evolving from digital gold into a global currency</a> used by millions worldwide — and as this momentum continues to grow, more apps want to tap into its ability to bring permissionless peer-to-peer payments to anyone, anywhere.That’s where Breez and Spark come in. Breez builds the services developers need to bring self-custodial Lightning payments to their apps. <a href="https://www.spark.info/">Spark</a> is a Bitcoin-native L2 built for payments and settlement so developers can build natively on Bitcoin instead of around&nbsp;it.And now, Breez and Spark are joining&nbsp;forces.We’re excited to announce a new implementation of the <a href="https://breez.technology/sdk/">Breez SDK</a>, built on top of Spark, making it even easier for developers to add Bitcoin payments to everyday apps and services. The new implementation brings developers everything needed for a best-in-class Lightning experience — including bindings for all major programming languages and frameworks, support for LNURL and Lightning addresses, and real-time user interaction via mobile notifications.Built on Spark, this implementation provides a Bitcoin-native experience without relying on bridges or external consensus. The new SDK implementation gives builders new ways to unlock the power of Bitcoin as a global, permissionless currency in various use cases like streaming payments for content, monetizing social apps, in-game currencies, cross-border remittances, AI micro-settlements, and many&nbsp;more.<blockquote>“We need developers to bring Bitcoin into apps people use every day,” said Roy Sheinfeld, CEO of Breez. “That’s why we built the Breez SDK. We’re excited to build on Spark’s revolutionary architecture — giving developers a powerful new Bitcoin-native option and continuing to strengthen Lightning as the common language of Bitcoin.”</blockquote><blockquote>“This is what the future of Bitcoin looks like — fast, open, and embedded in the apps people use every day. By teaming up with Breez, we’re expanding the ecosystem and giving developers powerful, Bitcoin-native tools to build next-generation payment experiences. Together, we’re building the standard for global, peer-to-peer transactions,” said Kevin Hurley, creator of&nbsp;Spark.</blockquote><blockquote>“We’re excited to see what developers build with Spark; it’s very exciting to see this come to the world,” said David Marcus, co-founder and CEO of Lightspark.</blockquote>As part of the collaboration, Breez will also operate as a Spark Service Provider (SSP) — alongside Lightspark — helping facilitate payments and supporting the growth of Spark’s ecosystem. The new implementation will be released later this year, with technical specifications to&nbsp;follow.<img><a href="https://blog.breez.technology/breez-spark-a-new-way-to-build-on-bitcoin-5abc3fb515cb">Breez + Spark — A New Way to Build on Bitcoin</a> was originally published in <a href="https://blog.breez.technology">Breez Technology</a> on Medium, where people are continuing the conversation by highlighting and responding to this story.
