I tried paying a 100 sats invoice and boarding onchain funds. both actions charged me 330 sats fee (for boarding it was on top of tx fee). Who collects them?
There are not really fees in the sense that someone collects them. There are the dust amount that has to go into the fee anchor output that has to be put on the arkoor transaction.
Luckily, since bitcoin core recently merged support for ephemeral anchors, the output can have 0 value and this effect will be dropped. We decided to ignore it for now because it will be resolved once most mempools allow for 0-value fee anchors.
To follow progress, you can follow this issue on our repo.
We can fix this issue once bitcoin 29 is released.
This release will include #30239 which allows us to set the value of each anchor to 0.
