To set up a Lightning node with a remote signer using litd, you configure the litd deployment to separate key custody from the routing node. This involves generating signer files, securely transferring credentials, and enabling watch-only routing operations via systemd.

A Neutrino backend provides a lightweight Lightning node operation, while a bitcoind backend offers a fuller, fully validating deployment. The litd stack supports both configurations, allowing you to choose based on your available resources and security requirements.

Configuring systemd services for a production LND deployment on Ubuntu involves creating service files that manage the litd startup process. This ensures your Lightning node, whether a routing or signer node, runs continuously and restarts automatically on failure.

Yes, you need Go and Node.js to install litd. The deployment process also requires Yarn to build the necessary components, ensuring the Lightning node stack and its remote signer workflow operate correctly in a production environment.

The litd remote signer architecture secures Lightning node keys by isolating key custody from the routing node. It generates specific signer files and transfers credentials to a separate machine, enabling the routing node to operate in a watch-only capacity.

Yes, you can operate a single Lightning node without a separate remote signer. The litd configuration supports single node deployments on Ubuntu alongside signer node and routing node setups, utilizing either Neutrino or bitcoind backends.
