Lightning Dev Kit: Making Lightning More Accessible to Developers
summary
Lightning Dev Kit is a Rust library that implements the full Lightning state machine and on‑chain enforcement as a lightweight, embeddable API rather than a daemon. It runs on mainnet nodes today, supports written in Rust code with callable C, Java and Swift bindings, scales from single‑thread mobile use to many cores, offers pluggable chain sync and storage, and supports remote signing via the Lightning Steiner project. Four full‑time engineers at Square fund it; two downstream apps aim for production this year.
