lightning-openchannel\_update -- Command to update a collab channel open ======================================================================== SYNOPSIS -------- **openchannel_update** *channel_id* *psbt* DESCRIPTION ----------- `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 `openchannel_init` or a previous call to `openchannel_update`) will be communicated to the peer. Must be called after `openchannel_init` and before `openchannel_signed`. 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 `openchannel_update`. *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 `openchannel_init` or `openchannel_update`. RETURN VALUE ------------ On success, returns the *channel_id* for this channel; an updated, potentially complete *psbt* for this channel's funding transaction; and the flag *commitments_secured*, which indicates the completeness of the returned *psbt*. If *commitments_secured* is true, caller should proceed with signing the returned PSBT and calling `openchannel_signed` to complete the channel open. If *commitments_secured* is true, will also return: - The derived *channel_id*. - A *close_to* script, iff a `close_to` address was provided to `openchannel_init` and the peer supports `option_upfront_shutdownscript`. - The *funding_outnum*, the index of the funding output for this channel in the funding transaction. - -32602: If the given parameters are wrong. - -1: Catchall nonspecific error. - 305: Peer is not connected. - 309: PSBT missing required fields - 311: Unknown channel id.
