mrkd started enforcing the `name -- short description` style of top-level headings somewhere, and was thus failing to build the man-pages. I swapped the title and with the existing short description to make it work again. `mrkd` will automatically infer the section from the filename so no need to put it in the title as well. In addition I removed the "last updated" lines at the bottom since they are out of date at best, and misleading at the worst. If we want to keep them, I'd suggest generating them from the commit that last touched them.

.SH NAME
|
||
lightning-fundchannel - Command for establishing a lightning channel
|
||
.SH SYNOPSIS
|
||
|
||
\fBfundchannel\fR \fIid\fR \fIsatoshi\fR [\fIfeerate\fR \fIannounce\fR] [\fIminconf\fR]
|
||
[\fIutxos\fR]
|
||
|
||
.SH DESCRIPTION
|
||
|
||
The \fBfundchannel\fR RPC command opens a payment channel with a peer by
|
||
committing a funding transaction to the blockchain as defined in BOLT
|
||
#2\. \fBfundchannel\fR by itself does not attempt to open a connection\. A
|
||
connection must first be established using \fBconnect\fR\. Once the
|
||
transaction is confirmed, normal channel operations may begin\. Readiness
|
||
is indicated by \fBlistpeers\fR reporting a \fIstate\fR of CHANNELD_NORMAL
|
||
for the channel\.
|
||
|
||
|
||
\fIid\fR is the peer id obtained from \fBconnect\fR\.
|
||
|
||
|
||
\fIsatoshi\fR is the amount in satoshis taken from the internal wallet to
|
||
fund the channel\. The string \fIall\fR can be used to specify all available
|
||
funds (or 16777215 satoshi if more is available)\. Otherwise, it is in
|
||
satoshi precision; it can be a whole number, a whole number ending in
|
||
\fIsat\fR, a whole number ending in \fI000msat\fR, or a number with 1 to 8
|
||
decimal places ending in \fIbtc\fR\. The value cannot be less than the dust
|
||
limit, currently set to 546, nor more than 16777215 satoshi\.
|
||
|
||
|
||
\fIfeerate\fR is an optional feerate used for the opening transaction and as
|
||
initial feerate for commitment and HTLC transactions\. It can be one of
|
||
the strings \fIurgent\fR (aim for next block), \fInormal\fR (next 4 blocks or
|
||
so) or \fIslow\fR (next 100 blocks or so) to use lightningd’s internal
|
||
estimates: \fInormal\fR is the default\.
|
||
|
||
|
||
\fIannounce\fR is an optional flag that triggers whether to announce this
|
||
channel or not\. Defaults to \fBtrue\fR\. An unannounced channel is considered
|
||
private\.
|
||
|
||
|
||
Otherwise, \fIfeerate\fR is a number, with an optional suffix: \fIperkw\fR means
|
||
the number is interpreted as satoshi-per-kilosipa (weight), and \fIperkb\fR
|
||
means it is interpreted bitcoind-style as satoshi-per-kilobyte\. Omitting
|
||
the suffix is equivalent to \fIperkb\fR\.
|
||
|
||
|
||
\fIminconf\fR specifies the minimum number of confirmations that used
|
||
outputs should have\. Default is 1\.
|
||
|
||
|
||
\fIutxos\fR specifies the utxos to be used to fund the channel, as an array
|
||
of "txid:vout"\.
|
||
|
||
.SH RETURN VALUE
|
||
|
||
On success, the \fItx\fR and \fItxid\fR of the transaction is returned, as well
|
||
as the \fIchannel_id\fR of the newly created channel\. On failure, an error
|
||
is reported and the channel is not funded\.
|
||
|
||
|
||
The following error codes may occur:
|
||
|
||
.IP \[bu]
|
||
-1: Catchall nonspecific error\.
|
||
.IP \[bu]
|
||
300: The maximum allowed funding amount is exceeded\.
|
||
.IP \[bu]
|
||
301: There are not enough funds in the internal wallet (including fees) to create the transaction\.
|
||
.IP \[bu]
|
||
302: The output amount is too small, and would be considered dust\.
|
||
.IP \[bu]
|
||
303: Broadcasting of the funding transaction failed, the internal call to bitcoin-cli returned with an error\.
|
||
|
||
|
||
Failure may also occur if \fBlightningd\fR and the peer cannot agree on
|
||
channel parameters (funding limits, channel reserves, fees, etc\.)\.
