Installation

  1. Install poetry
  2. poetry install
  3. poetry run ./suez

Channel fee policy

You can set channel fees by passing --base-fee and --fee-rate parameters.

For example:

poetry run ./suez --base-fee 1000 --fee-rate 200

You can override the channel fee policy by changing the FeePolicy class.

Example implementation does the following:

  • sets lower fee rate for channels with mostly local balance
  • sets higher fee rate for channels with mostly remote balance
  • sets medium (close to specified) fee rate for balanced channels

You control the spread via the --fee-spread argument. By default --fee-spread is set to 0.0 (no spread).

For example:

poetry run ./suez --base-fee 1000 --fee-rate 500 --fee-spread 1.8

This will set the fee rate above 500 for channels with mostly remote balance and below 500 for channels with mostly local balance.

Lightning node support

Currently, Suez supports LND and c-lightning.

By default it uses LND (lncli).

You can use it with c-lightning as follows:

poetry run ./suez --client=c-lightning

If you need to pass additional options to the lncli/lightning-cli you can do so:

(single argument)

poetry run ./suez --client=c-lightning --client-args=--conf=/usr/local/etc/lightningd-bitcoin.conf

(multiple arguments)

poetry run ./suez --client-args=--rpcserver=host:10009 --client-args=--macaroonpath=admin.macaroon --client-args=--tlscertpath=tls.cert

Adding support requires writing a client similar to lndclient.py and instantiating it in suez.py.

Donate

You can tip me some satoshis via tippin.me/@pavolrusnak

or you can donate via Spontaneous AMP Payment (data field encodes tip=suez):

lncli sendpayment --amt 10000 --amp --dest 0385218f0e307b6a0e989d2a717d346942d96b4fd550e937de5f8ffe1568510a18 --data 7629168=7375657a

  • Earned fees calculation

    Earned fees calculation

    The earned fees calculation seems to be double the actual amount. The problem seems to be around here. I'm not sure why fees are counted on both the incoming and outgoing channels? The relay fee is only earned on the outgoing channel.

    Commenting out this line results in a calculation that seems closer.

    I checked the suez script calculation with this homemade script (could have its own flaw but I did check a daily period by hand and it was correct):

    lncli fwdinghistory --start_time -30d --max_events 5000 | grep '"fee"' | sed -nr 's/.*"([0-9]+).*/\1/p' | awk 'BEGIN {total=0;}{total+=$1;}END {print "Total: ",total}'

    On my node, even after applying the fix mentioned above, my script and suez still result in an earned fees discrepancy of 16 sats.

  • Commissions for channels, where funds run out

    Commissions for channels, where funds run out

    Hello,

    What's the point of setting low commissions for channels where your balance is depleted? Thus, you stimulate payments through such channels, but there is no liquidity in them for sending. It is bad for routing (payments through them are more likely will be FAIL but third-party wallets/senders will try to choose these channels as there are low commissions).

    It would be quite logical to increase the commission for its part where your local balance is low.

    P.S. Honestly, I do not understand - why use here the distribution of Gauss?

    Attempting to install suez on Ubuntu Ubuntu 20.04.3 LTS, but when running poetry install, I am receiving: No module named 'virtualenv.seed.via_app_data'.

    I am not sure what version of virtualenv is required, but mine is virtualenv 20.13.0

  • Remote fees

    Remote fees

    I think remote fees are not calculated correcty:

    https://github.com/prusnak/suez/blob/master/lndclient.py#L75

    self.channels[cin].remote_fees += fee

    The fee on the incoming channel (the remote party fee) is their base fee + amount * fee_rate but here you're using our fee.

    This should be:

    `self.channels[cin].remote_fees += (self.channels[cin].remote_fee_base + forward_amount * self.channels[cin].remote_fee_base / 10000) / 1000

    or something along these lines.

    What do you think @prusnak ?

  • Remote Node / Umbrel

    Remote Node / Umbrel

    Looking to run on a remote node (Voltage) and an Umbrel. I think this breaks because the lncli call has to be changed. I tried changing ["lncli"] in lndclient.py def _run with the call commands I would use but it fails still.

    Voltage lncli --rpcserver=xxxxx.votageapp.io:10009 --macaroonpath=/path/to/admin.macaroon --tlscertpath=""

    Umbrel docker exec -i lnd lncli

    C lightning support

    2. --client can be LND or C-Lightning
    3. --client-args - I needed to pass additional options to lightning-cli
    4. Fixed remote fee calculation in clnclient.py (not in lndclient.py)
    5. Added a new opener column (for both LND and C-LN)

  • Use RPC instead of lncli

    Use RPC instead of lncli

    It would be very nice to use the RPC API provided by lnd rather than relying on lncli being installed. I am trying to run suez in a Docker container and I'd rather not install lncli when it could directly communicate over RPC with lnd from another container.

    I saw that that the choice of backend is abstracted away in separate classes, one for lnd and one for c-lightning. So in theory I could just add another one for RPC. Did somebody already look into that? Or is there some good reason to rely on lncli?

    Confirming: is it dangerous to interrupt the script (e.g., via CTRL+C)?

    https://docs.lightning.engineering/lightning-network-tools/lnd/safety#prevent-data-corruption

    The following (non-exhaustive) list of things can lead to data corruption: [...] Aborting channel operation commands (see next chapter). [...]

    Next chapter (https://docs.lightning.engineering/lightning-network-tools/lnd/safety#dont-interrupt-lncli-commands):

    Things can start to take a while to execute if a node has more than 50 to 100 channels. It is extremely important to never interrupt an lncli command if it is manipulating the channel database, which is true for the following commands: [...] updatechanpolicy [...]

    Thus, I assume we should "never interrupt" suez.py?

    WIP Eclair support

    This change adds abstraction to enable multiple LN implementations and implements basic Eclair support. It is not yet capable of updating channel policy but can show all relevant channels.

    I seek feedback for this change first. It's also a bit hackish, I mainly wanted to make basic features work with my node for starters.
