Whats does commit fee do? Does this fee change trough time? Will I get it back when I close the channel?
Thanks!
Very good question!

There is also to take in consideration:
  • anchor reserve, like 330 sats/chan
  • channel reserve, like 1% from total size of the channel
  • commit fee is variable, depending on how much are the onchain fee at the moment.
And yes, once the channel is closed you get all back.
