SYNOPSIS
|
|
|
|
|
--------
|
|
|
|
|

DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
The **setchannelfee** 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 **listpeers** reporting a *state* of
|
|
|
|
|
CHANNELD\_NORMAL or CHANNELD\_AWAITING\_LOCKIN for the channel.
|
|
|
|
|
|
|
|
|
|
*id* is required and should contain a scid (short channel ID), channel
|
|
|
|
|
id or peerid (pubkey) of the channel to be modified. If *id* is set to
|
|
|
|
|
"all", the fees for all channels are updated that are in state
|
|
|
|
|
CHANNELD\_NORMAL or CHANNELD\_AWAITING\_LOCKIN.
|
|
|
|
|
|
|
|
|
|
*base* 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 *msat* or *sat*, or a number with three decimal places
|
|
|
|
|
ending in *sat*, or a number with 1 to 11 decimal places ending in
|
|
|
|
|
*btc*.
|
|
|
|
|
|
|
|
|
|
*ppm* 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 through 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.
|
|
|
|
|
|
|
|
|
|
RETURN VALUE
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
On success, an object with the new values *base* and *ppm* along with an
|
|
|
|
|
array *channels* which contains objects with fields *peer\_id*,
|
|
|
|
|
*channel\_id* and *short\_channel\_id*.
