lightning-setchannelfee -- Command for setting specific routing fees on a lightning channel =========================================================================================== SYNOPSIS -------- **setchannelfee** *id* [*base*] [*ppm*] [*enforcedelay*] 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. *enforcedelay* is the number of seconds to delay before enforcing the new fees (default 600, which is ten minutes). This gives the network a chance to catch up with the new rates and avoids rejecting HTLCs before they do. This only has an effect if rates are increased (we always allow users to overpay fees), only applies to a single rate increase per channel (we don't remember an arbitrary number of prior feerates) and if the node is restarted the updated fees are enforced immediately. RETURN VALUE ------------ [comment]: # (GENERATE-FROM-SCHEMA-START) On success, an object is returned, containing: - **base** (u32): The fee_base_msat value - **ppm** (u32): The fee_proportional_millionths value - **channels** (array of objects): channel(s) whose rate is now set: - **peer_id** (pubkey): The node_id of the peer - **channel_id** (hex): The channel_id of the channel (always 64 characters) - **short_channel_id** (short_channel_id, optional): the short_channel_id (if locked in) [comment]: # (GENERATE-FROM-SCHEMA-END) ERRORS ------ The following error codes may occur: - -1: Channel is in incorrect state, i.e. Catchall nonspecific error. - -32602: JSONRPC2\_INVALID\_PARAMS, i.e. Given id is not a channel ID or short channel ID.
