c-lightning

c-lightning has not experienced any major scandals, hacks, or criminal charges. c-lightning is open source and non-custodial. As an experimental DIY project, its security depends on proper assembly, firmware handling, and cautious usage, making it more suited for developers, researchers, or advanced users than mainstream adoption.

c-lightning was created by Henrik Jonsson (hkjn), a developer working on Bitcoin and Lightning Network-related projects, with a focus on experimentation and hardware security.

c-lightning is a community-driven project rather than a commercial product.

c-lightning is designed to interact with c-lightning, a Lightning Network implementation for Bitcoin. The signed transactions can then be transferred back to the online environment for broadcasting, keeping private keys isolated from potentially compromised systems.

c-lightning was released around June 30, 2018 at a Hackaton as an experimental open-source DIY hardware wallet project for Lightning Network enthusiasts and developers.
