Internet-native paywalls with L402
2024-11-15 , Finney Stage

L402 is an open protocol that combines the power of HTTP and the Lightning Network to enable services to paywall access to their resources.

Developed by Lightning Labs, this protocol provides instant, low-cost, machine-friendly payments for the internet.

We will also discuss real-world use cases and the potential impact of L402 on the future of online monetization.


Built on top of the 402 HTTP payment required error code, the Lightning Network, and macaroons, the L402 protocol provides a secure and efficient way to implement paywalls for online resources.

The protocol flow is straightforward, and multiple open-source implementations are available, making it easy for developers to integrate L402 into their applications.

In this talk, we will explore the features, implementation, and extensibility of the L402 protocol. We will also dive into the technical details of the protocol, including its use of macaroons for authentication and authorization, and how it leverages the Lightning Network for fast and inexpensive transactions.

By the end of the talk, attendees will have a clear understanding of how L402 works and how they can start using it in their own projects.

Jordi Montes is the founder of Fewsats, a serverless platform designed to facilitate the monetization of products and services.

He is a well-known developer in the Lightning Network community. Known as "positiveblue" on GitHub, he is an LND contributor and a former Lightning Labs employee. His current focus is on building Fewsats and improving the L402 ecosystem.
