lightning-openchannel_update -- Command to update a collab channel open

SYNOPSIS

openchannel_update id psbt

DESCRIPTION

openchannel_update is a low level RPC command which continues an open channel with peer, as specified by 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.

id is the node id of the remote peer.

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.

• -32602: If the given parameters are wrong.
• -1: Catchall nonspecific error.
• 305: Peer is not connected.
• 306: Unknown peer id.
• 309: PSBT missing required fields
