Bitcoin infrastructure provider Breez has launched Glow, a dual-purpose application designed both as a user-friendly Lightning Network wallet and as a complete open-source reference implementation for developers. Available as a progressive web app and through the Apple App Store and Google Play, Glow combines everyday payment tools with transparent code that teams can examine, fork, and rebrand.

Seedless Access and Everyday Payment Features

Glow replaces traditional seed-phrase backups with passkey authentication, allowing users to sign in via face or fingerprint biometrics that sync across devices through iCloud or Google. The wallet supports native Lightning payments and customizable Lightning addresses that function like email addresses, such as [email protected]. Contacts can be saved and synced, simplifying repeated transfers.

Built-in on-ramps from Cash App and MoonPay enable users to acquire bitcoin quickly. The app also understands Lightning, Spark, and on-chain bitcoin rails so incoming payments settle without requiring the user to select a specific network.

Stablecoin Transfers and Volatility Management

Users can convert bitcoin balances into stable value on demand. Glow supports sending USDT and USDC drawn from a bitcoin balance across more than 30 networks through a partnership with Flashnet. A dedicated Stable Balance feature lets holders keep funds in USDB, a bitcoin-native stablecoin issued by Brale Inc. and deployed via the Spark protocol. Holders of USDB can earn sats generated from Flashnet trading activity.

The Breez SDK handles asset exchange in the background while maintaining Lightning compatibility through Spark integration. This combination allows users to send and receive in bitcoin or dollar-denominated value without managing multiple wallets or complex conversion steps.

Open-Source Design for Developers

Glow is released under an MIT license as free and open-source software. Developers can inspect the full codebase to see how passkey login, Lightning addresses, contacts, stablecoin transfers, and on-ramp integrations are implemented via the Breez SDK and API. Teams are encouraged to fork the application, rebrand it, and ship it under their own name. An AI-assisted guide is provided to streamline white-labeling.

Because applications built on the Breez SDK never take custody of user funds, private keys and spending authority remain solely with the end user. Breez states this structure keeps regulatory requirements limited, allowing development teams to concentrate on product features rather than compliance infrastructure.

Context of Recent Partnerships

The Glow release follows Breez’s collaboration with Turnkey announced the previous month. That partnership enables developers to add non-custodial bitcoin support to applications that host wallets on their own servers. Cryptographic keys stay outside application servers operated by Breez or Turnkey; the backend only manages roles and permissions while ultimate control over funds rests with the user. The arrangement is intended to remove a longstanding barrier that has discouraged large consumer platforms from integrating bitcoin.

Glow itself is powered by the Breez SDK–Spark stack and demonstrates production patterns already used by more than 100 applications. By packaging a fully functional wallet alongside transparent implementation details, Breez positions the release as both a consumer product and a practical blueprint for broader bitcoin integration.
