Welcome to Unit 7Lightning-Adjacent Protocols

Lightning developers should be aware of the many Lightning-adjacent protocols. Some of these protocols form the basis of the Lightning Network's most popular uses and enable its payment technologies. This unit covers popular protocols, such as NOSTR, LNURL, Lightning addresses, Taproot Assets, Lightning Service Providers, and submarine swaps. The unit includes hands-on coding practice because these protocols offer developer-friendly implementation options. You can start by reviewing the unit learning outcomes and then reviewing the unit resources.
