accumulator / charge-lnd Goto Github PK

Hey,
in the case of a very low balance score I'd like to change the max_htlc_msat to a lower amount. But because of different channelsizes it is difficult to choose a fixed amount which fits for all channels.
Because of this one should be able to configure it as a ratio of the capacity, e.g. with implentation of a new parameter max_htlc_msat_ratio.

Regards Steff

Whenever I tried to run charge-ldn container, I receive this error:
Traceback (most recent call last):
File "/usr/local/bin/charge-lnd", line 5, in

IsADirectoryError: [Errno 21] Is a directory: '/app/charge.config'

To prevent free zero base fee routing, I manually edit my min_htlc_msat to minimally receive 1 msat.

I have tried to implement this in the proportional routing, but have not succeeded yet.

Is it possible to add a toggle property, for example min_htlc_msat_zerobase = true
to adjust the min_htlc_msat accordingly with proportional strategies?

An example of what I had in mind:

min_htlc_msat_zerobasefee=(
if fee_rate is 0: min_htlc_msat
elseif fee_rate is >1000000: 1
elseif min_htlc_msat is 0: (1000*(1000/fee_rate))
else: min_htlc_msat

I was missing an inverse proportional setting as an addition to the encourage routing channels that have a high local balance.

Changing the ratio
from
ratio = channel.local_balance/(channel.local_balance + channel.remote_balance)
to
ratio = channel.remote_balance/(channel.local_balance + channel.remote_balance)
has the desired effect

I was not succesfull in implementing a new strategy in strategy.py, but could not find the issue.

How can I suggest a new strategy? Simply adding one in strategy.py did not work

--check does not check syntax error.

for
[new section]
node.id = something

I had a - instead of _ mistake in
max.chan-ratio (instead of max.chan_ratio

Also I had spelling mistake

strategy = proportional

These were not caught during --check and instead they were caught in --dry-run

While using verbose output I am getting the following error/stacktrace

Traceback (most recent call last):

    if min_fee_ppm_delta > abs(new_fee_ppm - current_fee_ppm):
TypeError: unsupported operand type(s) for -: 'NoneType' and 'int'

The prior output is from a node that was in a file list of nodes with a strategy of ignore.

When I took the pubkey of a node above it in the output and added it to the file the error occurs that that node. So it seems to be an issue in the ignore strategy when verbose is on.

Everything seems to work fine when verbose is off.

Would be great if charge-lnd supported connecting to electrum with TLS enabled

Looking for help with charge-lnd

Just installed and getting this when trying to do anything with it:

Big newbie pleb here, so be easy on me. ;)

Thanks!

Whenever a value changes charge lnd shows it in the output
for example if fee is changed from 300 to 250 it is shown as 300->250

when is channel is disabled as part of disable policy, it is shown as disabled.

but when it is renabeld it is not shown.

May be it can be shown as
enabled -> disabled
disabled -> enabled
on the respective state change.

Hey! I'm drooling over this awesome work, and really would love to see it added to Umbrel! Most Umbrel users are not SUPER technical, and even if they are, every upgrade would wipe out changes unless it was built into an Umbrel app via docker.

I'd love to see someone adapt this to Umbrel, so the many thousands of node operators running Umbrel OS could enjoy it!

I'm trying to separate my channel segmentation into different files, with the goal to write into those dynamically.
I've been able to pull in
node.id = file:///home/lnd/.config/test.list
with test.list formatting just as

039cbc938e8a9095b60114143cdb301ae4d4d9bd1dca96763a494880863ac66055,
02868e12f320073cad0c2959c42559fbcfd1aa326fcb943492ed7f02c9820aa399

When trying to apply similar logic to channel-IDs, none of the following worked:
chan.id = file:///home/lnd/.config/test.list
in the main file, formatting of the pulled test.list with short channel IDs

717384x1380x2,
721770x2518x4

breaking with the following error:
Ignored: invalid channel id '717384x1380x2,' in 'file:///home/lnd/.config/test.list'

or with long channel IDs

763135836514680834,
784400391425949697,
795851805125050369

breaks with the following errors

Error evaluating criteria for channel 710983x401x1 in policy '<charge_lnd.policy.Policy object at 0x7f9c9e3a2be0>', ignoring channel. (Error=invalid literal for int() with base 10: 'chan.id = file')

The policy section pulling it looks like this:

[1-Lowest-Normal]
chan.id = file:///home/lnd/.config/test.list
#chan.min_ratio = 0.05
strategy = proportional
min_fee_ppm = 30
max_fee_ppm = 90

Perhaps I'm using the wrong channel format, but lndmanage, lncli or LNDg which I'm using for exporting the long format.

Any way this is a bug, or I'm just using the wrong output for filtering the channel-ID?

Running when one of my peers is down, getting this error. Would be nice if charge continued with the other channels when this happens.

it's great that you have both Raspiblitz and Umbrel guides but there area also many interested MyNode users that would love to use charge-lnd but are intimidated by the process.

Based on the assumption that a channel is not used because it is too expensive, it might help to reduce the fees for that channel. It'd be great to have this as a policy (possibly in addition to other policies?).

Channel X has fee rate 1000, but hasn't been used in 4 days. Reduce fee to 1000 - 0.9 * 4/30 (up to 90% discount for 30 days without forwardings).

I'm not sure if this should count consecutive days without forwardings, or just fractions (x out of the last y days).

It would be great to have support for updatechanstatus

so to stop routing status can be set to Disable
to allow routing the status can be set to Enable.

This can be used with liquidity setting for example max.chan_ratio = 0.1, disbale channel.

Most people today use workaround to raise fees instead which has other issues.

I worked through jonathanalevi's guide (https://yalls.org/articles/97d67df1-d721-417d-a6c0-11d793739be9:0965AC5E-56CD-4870-9041-E69616660E6F/0d395aab-d85d-4039-a5cc-682950e89a9d) for my own Umbrel node, and I got it to work (although, I don't know that the crontab job was every repeating the command every hour, I suspect not). Now, though, I am getting the following error upon running the docker:

I'm a beginner at this stuff, so I hope someone can help me see where I've gone wrong. 

Hi, I think you need to put an empty init.py into the grpc_generated directory

at least that's what I needed for my install

https://hub.docker.com/r/accumulator/charge-lnd/tags?page=1&ordering=last_updated seems to still be on v0.1.2

Is there a reason for not accepting zero fee rate?

One of my peer MasterYoda has base_fee 199 sat and base_fee_rate 0
I have created special section to match the peer
However the strategy always reduced the base_fee to 0 instead of matching to 199 (and even if I manually reset to 199 in the next run it is replaced by 0).

The configuration file is

[9-static]
#Match to channels which keep high static fees
#MasterYoda

node.id = 033dee9c6a0afc40ffd8f27d68ef260f3e5e1c19e59c6f9bb607fb04c1d497a809

strategy = match_peer

To correct this for now I changed to

[9-static]
#Match to channels which keep high static fees
#MasterYoda

node.id = 033dee9c6a0afc40ffd8f27d68ef260f3e5e1c19e59c6f9bb607fb04c1d497a809

strategy = match_peer
base_fee_msat = 199_000

But this would not be good if the peer base fee changes in future (because I will remain at 199).

Last version was running fine. When doing a dryrun following error appears:

Traceback (most recent call last):
File "/usr/local/bin/charge-lnd", line 6, in

(new_base_fee_msat, new_fee_ppm, new_min_htlc, new_max_htlc, new_time_lock_delta) = policy.strategy.execute(channel)
AttributeError: 'NoneType' object has no attribute 'execute'

I'm not certain if this is possible so I'm just throwing this out there.
Currently there is an ignore strategy where if the criteria match the channel is exempted from the other blocks. But what if there was another strategy such that if the criteria matches then only will the other blocks be considered.
Here is a simple example but maybe I'm missing some nuances:
I have a config where there is an ignore block for excluding my "friend" nodes.
I have a second config only for my "friend" nodes.
In order to deal with the second case I would have to add the channel/node matching to each block in the second file as opposed to a single block at the top of the config that would exclude everyone that was not in my friends list.

Anyone have a recipe for this?

Have the following policy:

[idle-channel-2d]
chan.activity_period = 2d
chan.max_htlcs_out = 0
strategy = static
base_fee_msat = 0
fee_ppm = 350

Still the channel that had outgoing liquidity just 3 hours ago changed the fee based on this policy

In routing nodes, many forwards can happen and this creates too many fee updates that take time to travel the network (which causes new forwards to fail due to different fee).

The current solution is to update fees less often, but this can have the issue of having your channels out of balance quicker.

A threshold (either in change percentage, or absolute sats change) could be taken into account. This would make changes only happen after the threshold has been reached after many channel forwards, and then issue a fee update. This would limit the micromanagement of fee rates, while still be able to check them quick and update when it is necessary.

I (and a lot of others I imagine) would like to run charge-lnd in docker. However since I'm no docker expert and don't know how the docker image is set up i would like a sample config for running the container and a sample config for compose, so i can set up a config file and have the built in systemd service or cronjob or whatever inside the container take care of the rest.

Hello,
In the case of an empty line (espacially in the case of an empty file) or a commented line in a list of node-ids, the tool prints a warning that the pubkey is invalid. This should be suppressed.

Having a commented line would be helpful to descripe the node in the list.

Regards Steff

max_htlc_msat_ratio (or a new parameter) which can apply on the outbound capacity of the channel instead of total capacity.

It would be helpful if it were possible to define variables in the config file, i.e. scaling values, to make changing proportional values faster.

Doesn't work as is on remote node (Voltage)? Is it possible to add flags for remote node? ex: --macaroon-path "" --tlscert-path "" --socket "". Looks like macaroon and cert path are relying on local running instance of LND.

First of all, thank you very much for this amazing tool. It is GodSend to manage fee and therefore routing efficiently and to achieve an efficient return on liquidity deployed.

Now, it is well known the network is choked today due to "TemporaryChannelFailures" which is mainly a result of channel with depleted liquidity coming up higher in the routing path and failing. This is akin to a driver who fails to move to the side when running out of fuel and therefore blocking the fast lane.

To resolve this and to not cause inconvenience to my peers routing through me, I have started using base fee as a switch
BaseFee = 0 when routing is on from my side -> peer
BaseFee = 9999_000 mSat when routing is off from my side -> peer if liquidity is depleted.

I do this by putting a stop routing policy very high in (after default and my default) as below

[1-stop_routing]
# if < 10% on local increase fees very high
chan.max_ratio = 0.1
strategy = static
base_fee_msat = 9999_000
fee_ppm = 0

The advantage of using base fee instead of fee rate is simply because
a) most explorers look for fee-rate, very high fee rate could impact the ranking or optics.
b) by using base fee simply as on-off switch it offers a predictability to the peers
c) by consistently using 9999 as base fee to signal routing off, it also starts establishing 9999 as a signal for routing off instead of a desire to claim a very high fee. i.e. it is a service to the network instead of charging very high fee. As you can see, there is no liquidity to charge that high fee anyway, the route will fail.

If many nodes are adopting this strategy, soon we can see a reduction in temporary channel failures and the network will flow smoothly through paths which have liquidity.

Since charge-lnd is most used tool for fee management, if such a configuration can be introduced in SampleConfiguration then it will really encourage the network to adopt this.

If you agree, I can create a pull request for your review in the sample configuration file.

In the Example the following is described:

[zerobasefee-initiative]
#set base_fee_msat default to 0 if peer sets zero base fees
chan.max_fee_ppm = 0
base_fee_msat = 0

But in my understanding, this looks for the fee_rate of the peer, so in my view the should be something like:

chan.max_base_fee = 0

The above would mean if the peer has a feerate of 0 I will adjust my base_fee to 0 which is highly unlikely to happen.

I'm getting the following error message:

Error evaluating criteria for channel in policy '<charge_lnd.policy.Policy object at 0xb537a4d0>', ignoring channel. (Error=Unknown property 'chan.min_local_balance')

Hi,
im on Raspiblitz and i follow the instructions on: https://nullcount.com/install-charge-lnd-routing-fees-on-autopilot/
But when i enter the "pip install -r requirements.txt ."
i got this error msg:

Could not install packages due to an EnvironmentError: [('/home/bitcoin/charge-lnd/charge.config.save', '/tmp/pip-req-build-nqu2rchu/charge.config.save', "[Errno 13] Permission denied: '/home/bitcoin/charge-lnd/charge.config.save'")]
I'm a linux newbie and it would be great to get some help.

Channels often have only one flow direction.
For such channels, a strategy that increases or decreases fees based on activity could be useful.

Example:
[increase fee]
chan.activity_period = 1d
chan.max_htlcs_out = 3
strategy = increase
chan.current_fee = +0.1%

[decrease fee]
chan.activity_period = 1d
chan.max_htlcs_out = 1
strategy = decrease
chan.current_fee = -0.1%

In case of a match_peer strategy one should be able to set fee_ppm to the value of the peer but to configure the base fee individually.

Regards Steff

With lnd 0.13 it is possible to disable channels
lncli updatechanstatus --funding_txid 123 --output_index 0 --action disable

It would be helpfull if one can disable and enable a channel then with charge-lnd too, e.g. when the outbound amount is very low. At the moment I raise fees in that case. But it has the sideeffect that the average fee of the node on amboss is raising too.

Looking for a way to match on equivalent number of channels. Basically, a channel to a node that cannot route. For example, I have 2 channels to node A, and A only has 2 channels. Use case is large deployments with root/leaf node structure.

AttributeError: 'NoneType' object has no attribute 'get'

My config file looks like this:

[discourage-routing-out-of-balance]
chan.max_ratio = 0.1
chan.min_capacity = 25000
strategy = static
base_fee_msat = 10000
fee_ppm = 500

[encourage-routing-to-balance]
chan.min_ratio = 0.9
chan.min_capacity = 25000
strategy = static
base_fee_msat = 1
fee_ppm = 2

Any idea what is wrong?

In addition to support for chan.max_ration/chan.min_ratio spport can be provided for absolute amount.

I would like to stop routing based on absolute amount below a certain liquidity level say 500_000_000 mSat because that is the average size through my node. However today I can only do it based on ratio < 0.1 which can be different for different channel size.

With some assistance from @Jorijn, I am working on creating an install guide for Umbrel users, allowing them to create a separate docker with charge-lnd (Because Umbrel is all dockerized, and I want to avoid it uninstalling and wiping out the changes every time users update).

I am trying to run this command:

docker run --platform linux/arm64/v8 --rm -it --network=umbrel_main_network -e GRPC_LOCATION=lnd:10009 -e LND_DIR=/data/.lnd -e CONFIG_LOCATION=/app/charge.config -v $(pwd)/umbrel/lnd:/data/.lnd -v $(pwd)/umbrel/apps/charge-lnd/charge.conf:/app/charge.config docker.pkg.github.com/accumulator/charge-lnd/charge-lnd:latest

However, I get this response:

docker: Error response from daemon: image with reference docker.pkg.github.com/accumulator/charge-lnd/charge-lnd:latest was found but does not match the specified platform: wanted linux/arm64v8, actual: linux/amd64.
See 'docker run --help'.

This is particularly confusing, because the Raspberry Pi 4B is 100% certainly ARM v8.

I cannot figure out how to get around this and get it to recognize the right platform in order to install, so I'm completely stuck.

Thanks for your help, all!

If you have multiple channels with the same peer, they are treated separately. However lnd protocol treats multiple channels as one for routing purposes and therefore uses the highest fees for any of the multiple channel.

Therefore you may end up in a situation where CH1 is 100% local and has fee setup to encourage routing and CH2 is 100% remote and has fees setup to discourage routing, both CH1 and CH2 end up with discourage routing because network graph would show high fees (for discourage routing) is applied.

Solution - treat the local + remote for all channels with same peer together and apply the same fees for all channels with same peer.

The max_htlc_msat = -1 option out of the BhaagBoseDK/charge-lnd fork whould be a great plus... thanks for your work
