Here's a `jq` command to get all the channels with discounts

`lncli describegraph | jq -r '.edges[] | (select((.node2_policy.custom_records."55555" != null) and (.node2_policy.custom_records."55555" != "0000000000000000") or (.node1_policy.custom_records."55555" != null) and (.node1_policy.custom_records."55555" != "0000000000000000"))) | .channel_id'`

Currently showing 5 (of 16 nodes on 0.18) with discounts

These two channels (to bfx-lnd0 and bfx-lnd1) offer -100ppm:

I'd like to tweak my toolset (rebalance-lnd, lnd-manageJ, some scripts) so that they are able to work with negative inbound fees. Furthermore, I'd like to get my feet wet and learn how I can optimize my routing node c-otto.de to offer negative inbound fees where appropriate.

I agreed three years ago: https://github.com/lightning/bolts/issues/835#issuecomment-839948788 :)

They should be called discounts rather then negative fees. Total fee your node charges for a forward cannot go negative. If I have already set 0 fee on a channel I want to flow outbound giving discounts on inbound channels won't help the situation.

No, see https://stacker.news/items/526895/r/C_Otto?commentId=526912

Negative inbound fees mean you have to pay instead of being paid?

You may open a channel to my node.

. Currently, no other node configured any (negative) inbound fees. Let's hope this changes soon :)

PS: rebalance-lnd automatically takes advantage of negative inbound fees (if you run lnd v0.18), no code change necessary.

Those two channels are those of https://amboss.space/node/025cd50e55b969a418e713b70076333ba1e25929e9e6ec5b937c30a8edc85cc82b. Currently, no other node configured any (negative) inbound fees. Let's hope this changes soon :)
