electronwall v0.3.2

⚡️🛡 Wildcards

electronwall can now filter payment routings along specific channels or channel pairs using an allowlists or a denylists.

In this release

Wild cards

To allow or deny HTLC forwards, you can either use a specific filter for a channel ID pair like 6629856x65537x0->7143424x65537x0 or filter, for example, all outgoing forwards to a channel like *->25328x256x0. Similarly, you can filter for incoming payments using *->25328x256x0.

You can also apply wildcards to filter for all public keys when using the channel acceptor.

Config changes

This release requires you to make appropriate changes in your config:

forward-mode: "allowlist"               # only one mode can be used at a time!
forward-allowlist:
  - "7143424x65537x0"                   # all forwards from this channel
  - "7143424x65537x0->*"                # same as above
  - "6629856x65537x0->7143424x65537x0"  # channel pair
  - "*->25328x256x0"                    # all forwards to this channel
forward-denylist:
  - "9961472x65537x1"
  - "*"                                 # this would deny all forward events in "denylist" mode
