A Bitcoin-Native Leap for Developers
The updated Breez SDK leverages Spark’s L2 architecture to deliver a frictionless, bitcoin-native experience for developers.
Key features include:
- Universal Compatibility: Bindings for all major programming languages and frameworks.
- LNURL & Lightning Address Support: Streamlined integration for peer-to-peer transactions.
- Real-Time Interaction: Instant mobile notifications for payment confirmations.
- No External Reliance: Built directly on bitcoin via Spark, eliminating bridges or third-party consensus.
This implementation unlocks use cases such as streaming content payments, social app monetization, in-game currencies, cross-border remittances, and AI micro-settlements—all powered by Bitcoin’s decentralized network.
