.SH SYNOPSIS
|
|
|
|
\fBopenchannel_init\fR \fIid\fR \fIamount\fR \fIinitalpsbt\fR [\fIcommitment_feerate\fR] [\fIfunding_feerate\fR] [\fIannounce\fR] [\fIclose_to\fR]
|
|
|
|
.SH DESCRIPTION
|
|
|
|
\fBopenchannel_init\fR is a low level RPC command which initiates a channel
|
|
open with a specified peer\. It uses the openchannel protocol
|
|
which allows for interactive transaction construction\.
|
|
|
|
|
|
\fIid\fR is the node id of the remote peer\.
|
|
|
|
|
|
\fIamount\fR is the satoshi value that we will contribute to the channel\.
|
|
This value will be \fIadded\fR to the provided PSBT in the output which is
|
|
encumbered by the 2-of-2 script for this channel\.
|
|
|
|
|
|
\fIinitialpsbt\fR is the funded, incomplete PSBT that specifies the UTXOs and
|
|
change output for our channel contribution\. It can be updated,
|
|
see \fBopenchannel_update\fR; \fIinitialpsbt\fR must have at least one input to
|
|
provide a PoDLE to the peer\. Must have the Non-Witness UTXO
|
|
(PSBT_IN_NON_WITNESS_UTXO) set for every input\. An error
|
|
(code 309) will be returned if this requirement is not met\.
|
|
|
|
|
|
\fIcommitment_feerate\fR is an optional field\. Sets the feerate for
|
|
commitment transactions: see \fBfundchannel\fR\.
|
|
|
|
|
|
\fIfunding_feerate\fR is an optional field\. Sets the feerate for the
|
|
funding transaction\. Defaults to 'opening' feerate\.
|
|
|
|
|
|
\fIannounce\fR is an optional field\. Whether or not to announce this channel\.
|
|
|
|
|
|
\fIclose_to\fR is a Bitcoin address to which the channel funds should be
|
|
sent on close\. Only valid if both peers have negotiated
|
|
\fBoption_upfront_shutdown_script\fR\.
|
|
|
|
.SH RETURN VALUE
|
|
|
|
On success, returns the \fIchannel_id\fR for this channel; an updated
|
|
incomplete \fIinitialpsbt\fR for this funding transaction; and the flag
|
|
\fIcommitments_secured\fR, which indiciates the completeness of the
|
|
passed back \fIpsbt\fR\. (Will always be false)\. Also returns the
|
|
\fIfunding_serial\fR, indicating the serial_id of the funding output
|
|
in the \fIpsbt\fR\.
|
|
|
|
|
|
If the peer does not support \fBoption_dual_fund\fR, this command
|
|
will return an error\.
|
|
|
|
|
|
On error the returned object will contain \fBcode\fR and \fBmessage\fR properties,
|
|
with \fBcode\fR being one of the following:
