lightning-openchannel_update -- Command to update a collab channel open
openchannel_update channel_id psbt
openchannel_update is a low level RPC command which continues an open
channel, as specified by channel_id. An updated psbt is passed in; any
changes from the PSBT last returned (either from
a previous call to
openchannel_update) will be communicated to the peer.
Must be called after
openchannel_init and before
Must be called until commitments_secured is returned as true, at which point
openchannel_signed should be called with a signed version of the PSBT
returned by the last call to
channel_id is the id of the channel.
psbt is the updated PSBT to be sent to the peer. May be identical to
the PSBT last returned by either
