.SH DESCRIPTION
|
|
|
|
\fBopenchannel_update\fR is a low level RPC command which continues an open
|
|
channel, as specified by \fIchannel_id\fR\. An updated \fIpsbt\fR is passed in; any
|
|
changes from the PSBT last returned (either from \fBopenchannel_init\fR or
|
|
a previous call to \fBopenchannel_update\fR) will be communicated to the peer\.
|
|
|
|
|
|
Must be called after \fBopenchannel_init\fR and before \fBopenchannel_signed\fR\.
|
|
|
|
|
|
Must be called until \fIcommitments_secured\fR is returned as true, at which point
|
|
\fBopenchannel_signed\fR should be called with a signed version of the PSBT
|
|
returned by the last call to \fBopenchannel_update\fR\.
|
|
|
|
|
|
\fIchannel_id\fR is the id of the channel\.
|
|
|
|
|
|
\fIpsbt\fR is the updated PSBT to be sent to the peer\. May be identical to
|
|
the PSBT last returned by either \fBopenchannel_init\fR or \fBopenchannel_update\fR\.
