They calculate it for you. I have three open channels of different sizes and 430,000 total capability. I’ve paid three times I guess.

Ahh so if I can control the amount of payment below my capacity, I don’t have to open new channel and don’t have to pay another 3,000sats.
Thanks bro for your explanation!
Can you let me know a pubkey of your phoenix wallet? I want to check my theory that auto channel generation only create a channel between each phoenix wallets and acinq node. Is there any function to designate a target node for a channel creation?
I checked and that seems to be correct. All mine are ACINQ.
I don’t know the details, however I suspect having a channel, even private channel, has some challenges around remote force close or sending olds channel state - so watchtowers are really important to prevent your largely offline channel from having funds attempt to be stolen.
I’m guessing Phoenix provides this? I should know, but haven’t investigated further.
Yes, not possible with Phoenix. Blixt lets you open channels to your node. I’m not aware of any other wallet that have this flexibility on IOS. Breez allows it but I wasn’t able to confirm.
Breez also have that function as shown on this pics. You can play as you want using this Breez wallet.

It does, but did you successfully open a channel?
