lightning-openchannel_signed -- Command to conclude a channel open


openchannel_signed channel_id signed_psbt


openchannel_signed is a low level RPC command which concludes a channel
open with the specified peer. It uses the v2 openchannel protocol, which
allows for interactive transaction construction.

This command should be called after openchannel_update returns
commitments_secured true.

This command will broadcast the finalized funding transaction,
if we receive valid signatures from the peer.

channel_id is the id of the channel.

signed_psbt is the PSBT returned from openchannel_update (where
commitments_secured was true) with partial signatures or finalized
witness stacks included for every input that we contributed to the


On success, an object is returned, containing:

  • channel_id (hex): the channel id of the channel (always 64 characters)
  • tx (hex): the funding transaction
  • txid (txid): The txid of the tx

On error, the returned object will contain code and message properties,
with code being one of the following:

  • -32602: If the given parameters are wrong.
  • -1: Catchall nonspecific error.
  • 303: Funding transaction broadcast failed.
  • 305: Peer is not connected.
  • 309: PSBT missing required fields.
  • 311: Unknown channel id.
  • 312: Channel in an invalid state
