lightning-fundchannel_complete – Command for completing channel establishment


fundchannel_complete id txid txout


fundchannel_complete is a lower level RPC command. It allows a user to complete an initiated channel establishment with a connected peer.

id is the node id of the remote peer.

txid is the hex string of the funding transaction id.

txout is the integer outpoint of the funding output for this channel.

Note that the funding transaction MUST NOT be broadcast until after channel establishment has been successfully completed, as the commitment transactions for this channel are not secured until this command successfully completes. Broadcasting transaction before can lead to unrecoverable loss of funds.


On success, returns a confirmation that commitments_secured and the derived channel_id.

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.
  • 305: Peer is not connected.
  • 306: Unknown peer id.
