lightning-openchannel\_signed -- Command to conclude a channel open
===================================================================
SYNOPSIS
--------
**openchannel_signed** *channel_id* *signed_psbt*
DESCRIPTION
-----------
`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
PSBT.
RETURN VALUE
------------
On success, returns the *channel_id* for this channel; hex *tx* of the
published funding transaction; and *txid* of the funding transaction.
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.
- 309: PSBT missing required fields.
- 311: Unknown channel id.
