I use charge-lnd to set the rate. It is between 50 to 200 ppm at the moment. I am considering a new feature that allows people to pay points (like mortgage points) to get a zero-rate channel.

[small-cap] chan.max_capacity = 50_000_000 strategy = proportional max_fee_ppm = 200 min_fee_ppm = 50 sum_peer_chans = true
