nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm I've just sent 150,000 sats to the #AlbyHub on-chain savings address to open a channel and the hub now shows 134,592 sats. What happened to the rest?
Discussion
15$ channel fee?
The cost of opening a channel is in sats, not dollars. Mine cost about 16K sats. The size of my channel is 1,000,000 sats, but I only put up 100,000 sats for my side of the channel. The other side has put up 900,000 sats. There are those who understand the cost of this business and they charge accordingly.
"I've just sent 150,000 sats to the #AlbyHub ON-CHAIN savings address...." (also an on-chain address)
looks like the sats went into the reserve
Thats after you open a channel
my mistake, missed the onchain part
No worries. Looking at the transaction the entire 15k has gone to the address and nothing has been deducted from the receiving address. Not on-chain anyway.

what reserve? i't a main-net transaction from one address to another. It doesn't say anything about 10% of deposits going into some sort of reserve
Lightning channels require a reserve so that the channel has enough fees to close once itās depleted
I am glad I didn't use the cloud service now. So much more control if you use a Raspberry Pi with your own LND node. Kind of curious about this. Surely you didn't get charged that for an on-chain TX fee?
Are you really asking? š
I am using the Alby Hub on the Pi, but I use the LND node BTC address to send BTC to to top up for channel opening. I've not topped up in Alby Hub itself
nostr:npub1q5sah9f3p9kl7uqdeaqskqwmg74ktxx70e0093dzh4lpzcp3t0mqzxky65 can you explain this please? I now have a channel opening pending to zapstream for 100k with 8,000 sats of 150,000 sats left in the hub's on-chain wallet. That's an expense of 42k.
If you opened the channel with your own on-chain funds, you only paid the fees for the opening transaction. You can calculate the paid fees by viewing the funding transaction on the Node page.
Own channel also require a reserve of on-chain funds to close the channel again. In Alby Hub these funds are omitted from the balance to avoid that the user spends them accidentally. If you send us an email to support@getalby.com I can research more details 
Max, I've sent Bitcoin on-chain from my own wallet to the cloud's savings wallet. The channel opening came later. The discrepancy of the amount sent on-chain to fund the hub.
Can you send an email to support@getalby.com with the link to the funding transaction? š
I can do that this PM. Here is the tx ID I've shared in this thread. As you can see 150k sats were sent on-chain from my wallet to the hub's wallet: 61e827f73a9fb03ab12edce3a6a3c0399dea4bb33d8a6fbe18a582b401f0c8f6
Here the funding transaction for the zapstream channel. Channel fee 1,590 sats

The remaining balance in the on-chain funding address is 8,002 sats (which, I just noticed yesterday, doesn't even have a withdraw option).
Go to "Node" --> "Advanced" --> "Withdraw Savings Balance"
Do you have other channels that you've opened before with your on-chain balance?
No
Illtsend you an email about this later. As it stands right now depositing 150k sats and opening a 100k Channel to zapstream cost me 42,000 sats.
The paid fees are visible in the blockchain explorer. There are no additional fees charged.
I expect that you opened anchor channels which require a reserve to leave room for bumping the fee of the closing transaction. The reserve is not part of the onchain/ savings balance.
I will take this to email so I can take those transactions apart and attach screenshots. I literally said 10x in this thread that I DID NOT open an channel and that there was already 15k sats missing from the on-chain transaction when it was received by the Hub though there is no indication as per why that would be the case. The FULL 150,000 sats was received by the hub's wallet. Also, opening the channel to zapstream was very cheap.
So I would like to know where and how I ended up with a 42k expense or 30% of the total amount.
Sounds good. Waiting for your email. A screenshot of the Node page would be helpful, too. š
They do charge like 25K sats for there cloud service it maybe that charge along with on chain fees
They billed me for the cloud a couple of days ago
Iām not loving Alby Hub. I feel there are weird things happening with the āsavings balanceā and the spendable balances in the channels.
When you pay someone to open a channel, instead of opening it yourself, you pay someone.
Whether the payment is worth the cost is something to learn. I found it a high maintenance endeavor to run a Lightning Node, with a number of channels.
Opening channels costs sats in onchain fees and the LSP that opens your channel also charges a fee. Would STRONGLY recommend opening larger channels in the future. Almost all beginner lightning issues trace back to small channels. I would advise ecash and custodial lightning unless you have at least 500k sats for a channel, with 1M being ideal. These unfortunately are the realities of lightning today.
you missed the point that this was an on-chain transaction from one wallet (my funding wallet) to the cloud's "savings wallet". You then use that balance to open channels. There is no reason that there should be any amount deducted from what has been sent.
Did you also check to see if itās the channel reserve? Thereās also always an amount set aside to be able to pay the onchain fee to close the channel in the future.
PEOPLE! Grinder knows how lightning works for fuck sake. Read the messages.
Heās asking why onchain-2-onchain transactions arenāt showing correctly. The transaction in the mempools is pretty cut and dry. š¤¦āāļø
