VLS separates your Lightning private keys and security rule validation from your Lightning node, into a discrete signing device. This improves LN security for users by reducing the attack surface.
As the Lightning network implementations of Taproot, Musig2 and FROST mature in the coming months, VLS will be a necessity in creating seamless multi-sig Lightning network channels.
High security through small attack surface. Refined policy controls.
Rust enables deployment on microcontroller, HSM, server, browser and mobile.
Control custody at the signer, instead of at the node. Separation of duties.
