Lightning Network expands with simplified payments without managing nodes

In April 2025, Breez, a company focused on solutions for the Bitcoin Lightning Network, announced that its software development kit (SDK) now supports Webassembly (WASM). Developed by the Breeez team, this update allows developers to integrate payments with Bitcoin into web applications and node.js -based environments, with the aim of simplifying access to rapid transactions in the second Bitcoin layer.

Breeez’s solution focuses on making the Lightning network, which as cryptooticias reported is a secondary bitcoin layer designed to process transactions more efficiently and quickly, is accessible on web environments. This allows applications such as social networks or content platforms They can incorporate functions such as tips or monetization in Bitcoin directly into a web browser.

To achieve this, Breez has adapted his technical infrastructure, exceeding the limitations of browsers, such as the lack of direct access to the file system or the difficulty in handling traditional databases.

A key aspect of this integration is the approach “nodess”(Without node) of the SDK, a term that refers To eliminate the need for developers or users to maintain complete nodes of Bitcoin or Lightning. Instead of requiring complex configurations, the SDK manages the connections to the light network transparently, using external services for tasks such as data synchronization or transaction validation.

This reduces the technical load, allowing even light web applications to offer payments with Bitcoin without compromising decentralization or safety.

Breez’s technical approach addresses multiple challenges.

For example, to manage network data, which normally requires heavy tools, a lighter alternative was implemented.

“Electrum is not viable in browsers, so we integrate support for 𝚆𝚊𝚝𝚎𝚛𝚏𝚊𝚕𝚕𝚜 as a light blockchain data source.”

Likewise, persistent storage, an obstacle in web environments, was resolved with a specific configuration: “Since traditional databases are a challenge in WASM, we use a SQLite configuration in memory adapted by 𝚛𝚞𝚜𝚚𝚕𝚒𝚝𝚎 and add a personalized persistent observer to handle the state.”

Wasm compatibility too It required deep adjustments in the SDK nucleus:

“We update the 𝚜𝚍𝚔-𝚌𝚘𝚖𝚖𝚘𝚗 crrate so that it works in Wasm environments through: the integration of a Wasm compatible GRPC customer using 𝚝𝚘𝚗𝚒𝚌_𝚠𝚎𝚋_𝚠𝚊𝚜𝚖_𝚌𝚕𝚒𝚎𝚗𝚝_𝚌𝚕𝚒𝚎𝚗𝚝, the implementation of a personalized DNS resolution for Wasm, the refactorization of the internal rest client to eliminate units not compatible with wasm and the introduction of a new crrate 𝚜𝚍𝚔-𝚖𝚊𝚌𝚛𝚘𝚜 for support of shared macros Platforms. “

In addition, Breez created a dedicated module for Wasm that facilitates the interaction with the SDK: “We add a dedicated Wasm interface using 𝚠𝚊𝚜𝚖-𝚋𝚒𝚗𝚍𝚐𝚎𝚗, with personalized management of types and call returns to offer a fluid experience for developers.“

Connectivity with Breez’s services, such as real -time synchronization, ensured through:

“All GRPC-based services (for example, the Breez server and real-time synchronization) now support proxies 𝚐𝚁𝙿𝙶-𝚆𝚎𝚋, allowing complete connectivity from browser environments.”

According to Breez, these technical adaptations They allow the SDK to function efficiently in browsersmaintaining the robustness of the light network.

According to the official Breez documentation, developers can implement payments peer-to-peer (P2P) with only a few lines of code. To illustrate this, Breez offers a demonstration application that shows how to create a Wallet Lightning in a browser, evidencing the potential of this integration.

Breez SDK Wasm compatibility seeks to solve a practical problem: bring payments with Bitcoin to web environments where they were previously unfeasible through Lightning.

This update expands the scope of the light network, and although it still requires that private developers implement it in trade applicationsIt makes it possible for more businesses and people to adopt decentralized payments in Bitcoin. Breez also commented that his update brought other novelties.

For example, now the minimum payment amounts have been significantly reduced: they can be sent from 21 Sats (the minimum unit of 1 BTC) receiving from 100 onwards.

Additionally, users can already pay fees with assets that are not Bitcoin (BTC), such as Tether (USDT).
