100 sats \ 0 replies \ @DarthCoin 9 Jan \ parent \ on: LN channel reserve question bitcoin_beginners
The commit fee is changing based on mempool fees. That is affecting directly your channels "can send" and is very visible on smaller channels.
But the channel reserve is mostly 1%. I think is possible to set thet % in your node settings, but I never use it.
Read here more about commit fee:

Then you have also the channel buffers:

Then you have also the anchor reserves. I suggest to always have a UTXO of max 100k sats in your node onchain wallet, that can be used for these anchor reserves and bumping fees for opening/closing channels.
That's why not all wallet and node interface, will show up the correct "can send" or can receive" because are many other hidden aspects and sometimes in their inteface is quite hard to be reflected. But as a user you always have to take them in consideration. when is about to send or receive into a channel.
