.SH NAME

|
lightning-openchannel_init - Command to initiate a channel to a peer
|
|
.SH SYNOPSIS
|
|
|
|
\fBopenchannel_init\fR \fIid\fR \fIamount\fR \fIinitalpsbt\fR [\fIcommitment_feerate\fR] [\fIfunding_feerate\fR] [\fIannounce\fR] [\fIclose_to\fR] [\fIrequest_amt\fR] [\fIcompact_lease\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\.
|
|
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\.
|
|
|
|
|
|
\fIrequest_amt\fR is an amount of liquidity you'd like to lease from the peer\.
|
|
If peer supports \fBoption_will_fund\fR, indicates to them to include this
|
|
much liquidity into the channel\. Must also pass in \fIcompact_lease\fR\.
|
|
|
|
|
|
\fIcompact_lease\fR is a compact represenation of the peer's expected
|
|
channel lease terms\. If the peer's terms don't match this set, we will
|
|
fail to open the channel\.
|
|
|
|
.SH RETURN VALUE
|
|
|
|
On success, an object is returned, containing:
|
|
|
|
.RS
|
|
.IP \[bu]
|
|
\fBchannel_id\fR (hex): the channel id of the channel (always 64 characters)
|
|
.IP \[bu]
|
|
\fBpsbt\fR (string): the (incomplete) PSBT of the funding transaction
|
|
.IP \[bu]
|
|
\fBcommitments_secured\fR (boolean): whether the \fIpsbt\fR is complete (always \fIfalse\fR)
|
|
.IP \[bu]
|
|
\fBfunding_serial\fR (u64): the serial_id of the funding output in the \fIpsbt\fR
|
|
|
|
.RE
|
|
|
|
If the peer does not support \fBoption_dual_fund\fR, this command
|
|
will return an error\.
|
|
|
|
|
|
If you sent a \fIrequest_amt\fR and the peer supports \fBoption_will_fund\fR and is
|
|
interested in leasing you liquidity in this channel, returns their updated
|
|
channel fee max (\fIchannel_fee_proportional_basis\fR, \fIchannel_fee_base_msat\fR),
|
|
updated rate card for the lease fee (\fIlease_fee_proportional_basis\fR,
|
|
\fIlease_fee_base_sat\fR) and their on-chain weight \fIweight_charge\fR, which will
|
|
be added to the lease fee at a rate of \fIfunding_feerate\fR \fI \fRweight_charge*
|
|
/ 1000\.
|
|
|
|
|
|
On error the returned object will contain \fBcode\fR and \fBmessage\fR properties,
|
|
with \fBcode\fR being one of the following:
|
|
|
