.SH "NAME"
|
|
lightning-setchannelfee \- Command for setting specific routing fees on a lightning channel\&.
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
\fBsetchannelfee\fR \fIid\fR [\fIbase\fR] [\fIppm\fR]
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
The \fBsetchannelfee\fR RPC command sets channel specific routing fees as defined in BOLT #7\&. The channel has to be in normal or awaiting state\&. This can be checked by \fBlistpeers\fR reporting a \fIstate\fR of CHANNELD_NORMAL or CHANNELD_AWAITING_LOCKIN for the channel\&.
|
|
.sp
|
|
\fIid\fR is required and should contain a scid (short channel ID), channel id or peerid (pubkey) of the channel to be modified\&. If \fIid\fR is set to "all", the fees for all channels are updated that are in state CHANNELD_NORMAL or CHANNELD_AWAITING_LOCKIN\&.
|
|
.sp
|
|
\fIbase\fR is an optional value in millisatoshi that is added as base fee to any routed payment\&. If the parameter is left out, the global config value fee\-base will be used again\&. It can be a whole number, or a whole number ending in \fImsat\fR or \fIsat\fR, or a number with three decimal places ending in \fIsat\fR, or a number with 1 to 11 decimal places ending in \fIbtc\fR\&.
|
|
.sp
|
|
\fIppm\fR is an optional value that is added proportionally per\-millionths to any routed payment volume in satoshi\&. For example, if ppm is 1,000 and 1,000,000 satoshi is being routed trhough the channel, an proportional fee of 1,000 satoshi is added, resulting in a 0\&.1% fee\&. If the parameter is left out, the global config value will be used again\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
On success, an object with the new values \fIbase\fR and \fIppm\fR along with an array \fIchannels\fR which contains objects with fields \fIpeer_id\fR, \fIchannel_id\fR and \fIshort_channel_id\fR\&.
|
|
.SH "ERRORS"
