Using this script you can easily rebalance individual channels of your lnd node.
This script needs an active lnd (https://github.com/lightningnetwork/lnd) instance running.
You need to have admin rights to control this node.
By default this script connects to
localhost:10009, using the macaroon file in
If you need to change this, please have a look at the sources.
You need to install Python. The gRPC dependencies can be installed by running:
$ pip install -r requirements.txt
Command line arguments
usage: rebalance.py [-h] [-r RATIO] [-l] [-o | -i] [-f CHANNEL] [-t CHANNEL] [-a AMOUNT] [--max-fee-factor MAX_FEE_FACTOR] optional arguments: -h, --help show this help message and exit -r RATIO, --ratio RATIO (default: 50) ratio for channel imbalance between 1 and 50, eg. 45 to only show channels (-l) with less than 45% of the funds on the local (-i) or remote (-o) side list candidates: Show the unbalanced channels. -l, --list-candidates list candidate channels for rebalance -o, --outgoing lists channels with less than x% of the funds on the remote side (see --ratio) -i, --incoming (default) lists channels with less than x% of the funds on the local side (see --ratio) rebalance: Rebalance a channel. You need to specify at least the 'to' channel (-t). -f CHANNEL, --from CHANNEL channel ID of the outgoing channel (funds will be taken from this channel) -t CHANNEL, --to CHANNEL channel ID of the incoming channel (funds will be sent to this channel). You may also use the index as shown in the incoming candidate list (-l -i). -a AMOUNT, --amount AMOUNT Amount of the rebalance, in satoshis. If not specified, the amount computed for a perfect rebalance will be used (up to the maximum of 4,294,967 satoshis) --max-fee-factor MAX_FEE_FACTOR (default: 10) Reject routes that cost more than x times the lnd default (base: 1000 msat, rate: 1 millionth msat) per hop on average
List of channels
rebalance.py -l (or
rebalance.py -l -i) to see a list of channels which
can be rebalanced.
This list only contains channels where less than 50% of the total funds are on
the local side of the channel.
You can also see the list of channels where less than 50% of the total funds
are on the remote side of the channel by running
rebalance.py -l -o.
-r/--ratio to configure the sensitivity ratio (default is 50 for 50%).
As an example,
rebalance.py -l -o -r 10 only shows channels where less than
10% of the total funds are on the remote side of the channel.
As an example the following indicates a channel with around 17.7% of the funds on the local side:
(23) Channel ID: 123[...]456 Pubkey: 012345[...]abcdef Local ratio: 0.176 Capacity: 5,000,000 Remote balance: 4,110,320 Local balance: 883,364 Amount for 50-50: 1,613,478 |===== |
By sending 1,613,478 satoshis to yourself using this channel, a ratio of 50% can be achieved. This number is shown as "Amount for 50-50".
The last line shows a graphical representation of the channel.
The total width is determined by the channel's capacity, where a channel with maximum capacity (16,777,215 satoshis)
occupies the full width of your terminal.
The bar (
=) indicates the funds on the local side of the channel.
The number next to the channel ID (23 in the example) can be used to directly reference this channel.
Rebalancing a channel
To actually rebalance a channel, run the script and specify the channel to send funds to using
Optionally you can also specify the channel to take the funds from (using
-f), and the amount to send (using
You specify the channel(s) using the channel ID, as shown in the output of
rebalance.py -t 123[...]456 -a 1613478
It is also possible to indicate the
--to/-t channel by the number shown next to the channel ID (23 in the example).
rebalance.py -t 23 -a 1613478
If you do not specify the amount, the rebalance amount for the destination channel (
-t) is determined automatically.
If you specify a channel using
-f, the funds are taken from that channel.
The maximum amount you can send in one transaction currently is limited (by the protocol) to 4,294,967 satoshis.
