lightning-connect – Command for connecting to another lightning node


connect id [host port]


The connect RPC command establishes a new connection with another node in the Lightning Network.

id represents the target node’s public key. As a convenience, id may be of the form id@host or id@host:port. In this case, the host and port parameters must be omitted.

host is the peer’s hostname or IP address.

If not specified, the port defaults to 9735.

If host is not specified, the connection will be attempted to an IP belonging to id obtained through gossip with other already connected peers.

If host begins with a / it is interpreted as a local path, and the connection will be made to that local socket (see bind-addr in lightningd-config(5)).

Connecting to a node is just the first step in opening a channel with another node. Once the peer is connected a channel can be opened with lightning-fundchannel(7).


On success the peer id is returned.

The following error codes may occur:

  • -1: Catchall nonspecific error. This may occur if the host is not valid or there are problems communicating with the peer. connect will make up to 10 attempts to connect to the peer before giving up.
