I installed Phoenix and some other wallets months ago, but never learned how to use them, and frankly am pretty rusty on self-custody lightening as well.
So - where to go for basic questions? Is there a telegram group or something?
More details - I'm just trying to withdraw from Stacker News, so I'm submitting a Phoenix invoice to Stacker.new, and it fails. Phoneix says "Payment rejected. The fee was 6944 sats, which is more than 50% of the amount"
My inbound liquidity is more than the amount I'm trying to receive into Phoenix. So shouldn't that be good?
There is email support, but if there's a group of Phoenix Wallet enthusiasts online somewhere, answering questions, that would be ideal. I don't want to bug developers.
Meanwhile, I will go watch some phoenix videos...
So - somebody pointed me to this telegram group:
It doesn't appear to be official, but does anyone have experience with it?
Initial impressions are reasonable.

Do not miss these videos

The hour glass visual was excellent (believe that's in the 2nd vid?). Probably the most helpful way of explaining channel capacity that I've seen.

Thanks, I watched the videos and about 13 minutes into the second one, the whole inbound liquidity issue came up.
I'm still not really getting it, because the amount I was requesting to come into my Phoenix wallet was way less than half of the inbound liquidity. I finally got it to work with an invoice of 1000, where the inbound liquidity was around 8000.
I wonder if things would make more sense if I tried another wallet, just to have a comparison between 2 self-custody lightening wallets. Like maybe Mutiny or something?
reply
I had that problem when the amount was close to the inbound liquidity. Just made a withdraw that was the amount i tried before and it worked. My inbound liquidity has 5x'd since the first time i tried.

You could open a different lightning wallet, maybe a custodial one, just to get a few sats built up. And withdraw your sn stash to that, just for the time being.
Because when you open a phoenix wallet, it'll try and open a channel for you, meaning, that's gonna cost a bunch! Like 20k sats or something
So if you're withdrawing your sats from sn to phoenix, it's trying to open a channel but you don't have enough sats yet and it'll cause an error
reply
As far as I can tell Phoenix tries to open a channel (or expand a channel) every single time you receive. It honestly makes it kind of a weird experience for people that are mostly receiving sats. I haven't managed to come up with a solution for this other than withdrawing directly to my node, which already has inbound liquidity available. Unfortunately, this is pretty bad privacy.
reply
Previous versions of the wallet did that.
Current Phoenix only opens one channel only and varies the amount dynamically in it.
reply
Ah was that was my legacy changeover thing that cost me a few sats!
reply
Probably, yeah, there were some on-chain transactions required for the migration.

I only started using Phoenix after they added splicing, and I always have high fees when receiving, but never when sending. If they're not doing a new transaction for each deposit into the wallet, then they're definitely being way too conservative with channel sizing.
In phoenix you have 1 channel, which can be grown or shrunk through a method called "splicing." When you have maxed out your inbound capacity, phoenix will make an onchain payment to grow the size of your channel.
A good practice here is to open a large channel (say, 500k-2m sats) and only need that on chain payment 1 time. If your channel is already open, expanding it (through splicing) to that range now while fees are relatively low is advisable.

You could also try to use the autowithdraw functionality of SN

Good tips here, thanks! Long story, Exodus is my lighting wallet after I couldn’t use Blue Wallet, now so want to look at Phoenix!
reply
I would try to build up a balance of sats in a custodial wallet (or on Liquid) to where you can make a large channel (maybe 500k+ sats). Self-custodial lightning isn't gonna be worth the tradeoffs with a channel of like 10-50k sats imo
reply
Lightning UX is hard, but channels have a channel reserve, which cannot be spent (but can be used to pay closing costs.) I don't know your channel size, but this may have been an issue. It's 1% of the total channel capacity typically.
reply
Is automated channel management on? If so it may try to open a channel with your withdrawal
