.SH SYNOPSIS
|
|
|
|
|
|
|
|

.SH DESCRIPTION
|
|
|
|
|
|
|
|
|
|
\fBopenchannel_signed\fR 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 \fBopenchannel_update\fR returns
|
|
|
|
|
\fIcommitments_secured\fR \fBtrue\fR\.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This command will broadcast the finalized funding transaction,
|
|
|
|
|
if we receive valid signatures from the peer\.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
\fIchannel_id\fR is the id of the channel\.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
\fIsigned_psbt\fR is the PSBT returned from \fBopenchannel_update\fR (where
|
|
|
|
|
\fIcommitments_secured\fR was true) with partial signatures or finalized
|
|
|
|
|
witness stacks included for every input that we contributed to the
|
|
|
|
|
PSBT\.
|
|
|
|
|
|
|
|
|
|
.SH RETURN VALUE
|
|
|
|
|
|
|
|
|
|
On success, returns the \fIchannel_id\fR for this channel; hex \fItx\fR of the
|
|
|
|
|
published funding transaction; and \fItxid\fR of the funding transaction\.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
On error, the returned object will contain \fBcode\fR and \fBmessage\fR properties,
|
