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.
