The Lightning Network Daemon (
lnd) - is a complete implementation of a
Lightning Network node.
lnd has several pluggable back-end
chain services including
neutrino (a new experimental light client). The project's codebase uses the
btcsuite set of Bitcoin libraries, and also
exports a large set of isolated re-usable Lightning Network related libraries
within it. In the current state
lnd is capable of:
lnd fully conforms to the Lightning Network specification
(BOLTs). BOLT stands for:
Basis of Lightning Technology. The specifications are currently being drafted
by several groups of implementers based around the world including the
lnd. The set of specification documents as well as our
implementation of the specification are still a work-in-progress. With that
said, the current status of
lnd's BOLT compliance is:
The daemon has been designed to be as developer friendly as possible in order
to facilitate application development on top of
lnd. Two primary RPC
interfaces are exported: an HTTP REST API, and a gRPC
service. The exported API's are not yet stable, so be warned: they may change
drastically in the near future.
An automatically generated set of documentation for the RPC APIs can be found at api.lightning.community. A set of developer resources including guides, articles, example applications and community resources can be found at: docs.lightning.engineering.
Finally, we also have an active
Slack where protocol developers, application developers, testers and users gather to
discuss various aspects of
lnd and also Lightning in general.
In order to build from source, please see the installation instructions.
To run lnd from Docker, please see the main Docker instructions
When operating a mainnet
lnd node, please refer to our operational safety
guidelines. It is important to note that
lnd is still
beta software and that ignoring these operational guidelines can lead to
loss of funds.
The developers of
lnd take security very seriously. The disclosure of
security vulnerabilities helps us secure the health of
lnd, privacy of our
users, and also the health of the Lightning Network as a whole. If you find
any issues regarding security or privacy, please disclose the information
responsibly by sending an email to security at lightning dot engineering,
