Suez

Tool for pretty printing and optimizing Lightning Network channels.

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 (both via lncli and via the REST API) and c-lightning.

By default it uses LND (lncli).

You can use it with c-lightning as follows:

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

You can connect to LND using the REST API as follows:

SSL_CERT_FILE=</path/to/tls.cert> poetry run ./suez --client=lnd-rest --client-args=rpcserver=https://<rpc-ip>:<rpc-port> --client-args=macaroonpath=</path/to/admin.macaroon> --client-args=tlscertpath=</path/to/tls.cert>

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.
