Breez

What Breez does

Breez is a private Bitcoin Lightning infrastructure company founded in 2018 and headquartered in Tel Aviv, Israel. The company develops the Breez SDK, a nodeless, non-custodial developer toolkit that enables application teams to integrate instant Bitcoin and stablecoin payments without operating Lightning nodes, managing channels, or handling liquidity. The SDK ships in two variants — Breez SDK - Spark (built on Spark, a Bitcoin-native Layer 2) and Breez SDK - Liquid (built on the Liquid sidechain via submarine swaps) — with language bindings for Kotlin, Swift, JS, React Native, Flutter, Go, Python, C#, and WASM. Supporting products include Misty Breez (reference mobile app), Glow Playground (open-source demo apps), and sub-products such as Passkey Login (WebAuthn-based seedless onboarding), Stable Balance (USDB holding), Spark Tokens (BTKN), and multi-tenant Server Mode.

The platform serves crypto wallets (Cake Wallet, Klever, Sorted), social applications (Primal, Club Orange), remittance platforms (Yolat, Bitnob), neobanks (Deblock), and swap/bridge aggregators (Exolix, Garden). Notable technical differentiators include WebAuthn PRF-based passkey wallet derivation, multi-device sync, multi-asset stablecoin support (USDB, with USDT/USDC forthcoming), and integrations with fiat on-ramps Cash App and MoonPay. Over 75 apps have integrated the SDK, reaching end users across 160+ countries, with Club Orange alone generating 6.6M+ transactions in its first year. The company is led by co-founder and CEO Roy Sheinfeld.

Breez's revenue model is primarily transaction-based: the SDK is free for developers (free API key, no usage fees, no seat limits), while end-users pay small base fees for sending and receiving payments through the integrated applications, and optional partner fees can be layered on (e.g., Misty Breez adds a 0.05% partner fee). The company has raised approximately $14 million across disclosed funding rounds, including a $5M round in January 2025 with investors including ego death capital, Entrée Capital, Plan B Fund, and Timechain, a $4.5M round in January 2025 with Concentric, and a prior $4.5M round in December 2022 led by ego death capital and Entrée Capital. Earlier funding includes a 2021 investment from Seetee (Aker's Bitcoin-focused subsidiary).

Core offering

Breez provides the Breez SDK, a developer toolkit that lets application teams embed instant, non-custodial Bitcoin payments via the Lightning Network, Spark, and Liquid Network without managing nodes, channels, or liquidity. The SDK ships in two variants - Breez SDK - Spark and Breez SDK - Liquid - and is offered free to developers while monetizing through small end-user transaction fees. A reference mobile app called Misty Breez showcases the SDK and serves as a white-label template.

Product overview

Breez offers the Breez SDK, a dual-implementation developer platform for embedding instant, non-custodial bitcoin into apps and services. The SDK ships in two variants: Breez SDK - Spark (built on Spark, a Bitcoin-native Layer 2) and Breez SDK - Liquid (built on the Liquid sidechain). Both variants are nodeless, meaning developers do not need to run Bitcoin nodes or manage Lightning channels. The platform also includes Misty Breez (a reference mobile app and white-label solution), Glow Playground (a demo of open-source apps built on the SDK), and sub-products such as Passkey Login, Stable Balance (USDB holding), Spark Tokens (BTKN), and Server Mode for multi-tenant deployments. The SDK is free for developers.

Direct peers

• Lightning Labs: Developer of LND, the dominant Lightning Network implementation, and tools like Lightning Loop and Pool. Direct competitor in providing Lightning developer infrastructure and SDKs.
• Blockstream: Developer of the Liquid Network (which Breez integrates with), Greenlight Lightning infrastructure, and other Bitcoin Layer 2 tools. Competes in Bitcoin scaling infrastructure and Lightning SDK space.
• Voltage: Managed Lightning node infrastructure provider offering hosted Lightning nodes and APIs for developers. Direct competitor in nodeless Lightning abstraction for app developers.
• Galoy Money: Open-source banking platform built on Bitcoin and Lightning, providing infrastructure for neobanks (including serving Bitcoin Beach Wallet). Competes in enabling Lightning-powered financial applications.
• Alby: Provides Lightning SDK for web browsers and web apps via the WebLN standard, plus custodial Lightning accounts. Overlaps with Breez on developer-facing Lightning abstraction for web integrations.
• Lightning Development Kit (LDK): Lightweight Lightning implementation maintained by Spiral (Block) for embedding Lightning into any application. Competes at the developer SDK layer, particularly for embedded Lightning use cases similar to Breez.

Emerging players

• Zeus Wallet: Open-source self-custodial Lightning wallet with embedded node support and merchant/LSP tools. Adjacent in providing non-custodial Lightning infrastructure, with a focus on wallet rather than SDK distribution.
• Ark Labs: Developer of the Ark Protocol and Arkade, a Bitcoin Layer 2 using Virtual Transaction Outputs (VTXOs). Direct partnership with Breez (Arkade launch, Oct 2025) but also a potential abstraction-layer competitor as Ark matures.

Broad incumbents

• Strike: Major Bitcoin Lightning payments company offering consumer and business payment products. Larger incumbent that uses Lightning under the hood and represents both a partner and competitive threat at the payments-application layer.

Others

• MoonPay: Crypto fiat on-ramp integrated into the Breez SDK for purchasing Bitcoin. Adjacent ecosystem participant rather than direct competitor — provides enabling infrastructure for Breez-powered apps.
