This describes 'fundchannel' as it works today. It definitely could use better error codes instead of -1 for everything.

.SH "NAME"
|
|
lightning-fundchannel \- Command for establishing a lightning channel\&.
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
\fBfundchannel\fR \fIid\fR \fIsatoshi\fR
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
The \fBfundchannel\fR RPC command opens a payment channel with a peer by commiting 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\&.
|
|
.sp
|
|
\fIid\fR is the peer id obtained from \fBconnect\fR\&.
|
|
.sp
|
|
\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\&. This value must be greater than the dust limit, currently set to 546\&. And it must be less than 1<<24 (approximately 0\&.16778 BTC)\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
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\&.
|
|
