Breez

Breez is a bitcoin technology company whose flagship product, the Breez SDK, is a best-in-class solution for developers to add instant, non-custodial bitcoin and stablecoin functionality to any app or service, removing third-party dependencies and letting value move as easily as information. The SDK is built on Spark (a native Bitcoin Layer 2) and Liquid, and offers features such as fully-featured Lightning support, multi-language/framework SDKs (Kotlin, Swift, JS, React Native, Flutter, Go, Python, C#, WASM), stable USD balances, passkey login, multi-device sync, a contacts API, integrated on-ramps, and multi-user server mode. More than 75 apps have integrated the Breez SDK, including crypto wallets (Klever, Cake Wallet, Sorted), neobanks (Deblock), social apps (Club Orange, Primal), and swap/remittance platforms (Garden, Exolix, Yolat). Breez also runs Glow, an open-source playground of reference apps (Glow App, Glow Pay, Glow Cloud) demonstrating bitcoin UX built with the SDK, and publishes a blog and newsletter ('Feel the Breez') covering bitcoin value-transfer topics. Its typical clients are developers and companies building wallets, payment apps, and social or fintech platforms that want to embed non-custodial bitcoin value transfer.
