.SH NAME
|
|
lightning-fundchannel_start - Command for initiating channel establishment for a lightning channel
|
|
.SH SYNOPSIS
|
|
|
|
\fBfundchannel_start\fR \fIid\fR \fIamount\fR [\fIfeerate\fR \fIannounce\fR \fIclose_to\fR \fIpush_msat\fR]
|
|
|
|
.SH DESCRIPTION
|
|
|
|
\fBfundchannel_start\fR is a lower level RPC command\. It allows a user to
|
|
initiate channel establishment with a connected peer\.
|
|
|
|
|
|
\fIid\fR is the node id of the remote peer\.
|
|
|
|
|
|
\fIamount\fR is the satoshi value that the channel will be funded at\. This
|
|
value MUST be accurate, otherwise the negotiated commitment transactions
|
|
will not encompass the correct channel value\.
|
|
|
|
|
|
\fIfeerate\fR is an optional field\. Sets the feerate for subsequent
|
|
commitment transactions: see \fBfundchannel\fR\.
|
|
|
|
|
|
\fIannounce\fR whether or not to announce this channel\.
|
|
|
|
|
|
\fIclose_to\fR is a Bitcoin address to which the channel funds should be sent to
|
|
on close\. Only valid if both peers have negotiated \fBoption_upfront_shutdown_script\fR\.
|
|
Returns \fBclose_to\fR set to closing script iff is negotiated\.
|
|
|
|
|
|
\fIpush_msat\fR is the amount of millisatoshis to push to the channel peer at
|
|
open\. Note that this is a gift to the peer -- these satoshis are
|
|
added to the initial balance of the peer at channel start and are largely
|
|
unrecoverable once pushed\.
|
|
|
|
|
|
Note that the funding transaction MUST NOT be broadcast until after
|
|
channel establishment has been successfully completed by running
|
|
\fBfundchannel_complete\fR, as the commitment transactions for this channel
|
|
are not secured until the complete command succeeds\. Broadcasting
|
|
transaction before that can lead to unrecoverable loss of funds\.
|
|
|
|
.SH RETURN VALUE
|
|
|
|
On success, returns the \fIfunding_address\fR and the \fIscriptpubkey\fR for the channel funding output\.
|
|
If a \fBclose_to\fR address was provided, will close to this address iff the \fBclose_to\fR address is
|
|
returned in the response\. Otherwise, the peer does not support \fBoption_upfront_shutdownscript\fR\.
|
|
|
|
|
|
On error the returned object will contain \fBcode\fR and \fBmessage\fR properties,
|
|
with \fBcode\fR being one of the following:
