Lightning Network Lenders' (and borrowers) discussion thread.

[Timelord2o67]

I appreciate the offer. We've been discussing the issue in our three threads (yours, mine and Loyce) over many weeks now.

I'm not walking away from LN, just not offering a testing loan service. The two loan threads are enough for now.

Need a favor. Can someone tell me if this QR code works? Trying to do something and I don't have my phone or tablet handy.



And if it does work what invoice info do you see?
I have been trying to script auto-generating invoices with QR codes and emailing them. I think I finally got it working.

Thanks,
Dave

"Test" and the amount 30,000 sats.

Having said that Blue took a really long time to think about it before displaying that & also took a longer time to process payment (I *think* it's gone through) + 154 minutes to expiry.

Please repay at:

*edit* Payment received.

Paid back. Thanks. Actually took 4 hops to get to you. Never seen that much routing for that small an amount before.
So the good news is that I can auto generate an invoice with a QR code and email it.
The bad news is, for some reason I can only do it once and then lnd refuses to do it a second time without a restart. Since I can generate them by hand through SSH it has to be something with my shitty code.
This is why I like playing with hardware more then software. Guess I am sticking with btcpay server for now.

Glad to help - is BTCpay a LN wallet, or online exchange?

[DaveF]

It's a self hosted payment server for BTC and Lightning.
I was trying to integrate it for my own use for when I send QuickBooks invoices. There is a kludge that does work, tried to do it my way. I wanted to send the invoice from QBooks and have a QR code attached to it with a lightning invoice that then got emailed to my customer.

Am just having a look around the website - looks good.

I've just connected to what I *think* is the bitpay LN node: https://1ml.com/node/0348eb55a7cd2332c3bcf5cf1bd81732d96d99caa56290de57eb02fac3c997d217 (at least it's not a (dot)onion web address)

What language are you trying to script in there? Bash, python, c?

I'd recommend trying python if you know how to use it as it's going to be easier than anything else, unless qrencode (that''s installed with bitcoin core) is able to handle it...

I  was using PHP, because the rest of the ticketing system is written in it so I went in with the attitude of how hard can this be.
The biggest issue (outside of the I am not a programmer) is that the person who wrote it thought they were the worlds best programmer and did a lot of work adding features that were never going to be used to make it "better". Do you really need the ability to change the font on the trouble ticket depending on the customer? And I kept running into those issues. (i.e. jobdescript2font undefined added that in the ini file and then jobdescript3font undefined)

Probably going to table it for now until we update QBooks after tax season. This way if anything else changes with it I Am not doing this again.

I have never done anything with php and probably won't for a while either.

If they've just put a load of random stuff together though it might not be the most secure thing to run for sending out invoices...

Does quickbooks work with bitcoin? I don't really have to worry about taxes as they just ask for estimates here so I try to give as accurate as possible but they don't care so much if somethings submitted wrong (especially if you overpay or it doesn't affect tax). (I normally just copy and pasta a column in electrum).

It's actually fairly secure since outside of the email server and the very basic front end for techs it's all offline in it's own little bubble.
The short version is enter ticket info. It sits there till someone goes to QBooks and pulls it. QBooks then emails the invoice using the email server info. The email server in QB is not a "real" email server. It looks and feels like it to QB and the other apps, but it's a bunch of PHP code that pulls together the invoice generated by QB, the trouble ticket / work order / any other documentation in the system and then it sends it to the real email server to be sent out.

So I go out in the field and install a UPS that is one of the stock ones we have.
I put it in the trouble ticket. The next morning the billing person pulls the info and sends the bill. You get an email with the bill, the list of work that I did and and PDF documentation about the UPS that we pre-loaded in the system.

That all works really well, just making changes is a pain.

@DaveF - is your application anything like this: Finmail - Send Bitcoin together with Email (Approved by Microsoft) which I just stumbled up on in another section of the forum.

No, someone wrote a custom piece of code. It's just pulling in and then sending it out. Not sending / receiving any payments just wanted to try to stick QR codes on the invoices.

Sorry, posted this in another thread. Had HW issues.

It's back up now. Still doing some other testing to make sure everything else is good.

I was about to ask if anyone knew of a link for the Wallet of Satoshi APK that doesn't involve google/apple stores, but then I saw this:

https://www.walletofsatoshi.com/disclosure.html

4. Customer Credit
a) Limit of $1000 or equivalent

Topping up a Wallet of Satoshi is restricted to a maximum total of $1000 AUD. Bitcoin and Lightning balances are also included in this total. If you attempt to credit your wallet with more than $1000 AUD equivalent, you will need to contact support@walletofsatoshi.com to get a refund.

which seems to me as though they have a propriety wallet similar to Blue Wallet but more draconian.

[jackg]

Hmmmm yeah they don't look like a good choice. Honestly custodial wallets for the lightning network seem a bad idea unless you won't be online for 2 weeks. Other than that, you should have enough time to publish a dispute or sign a new commitment transaction.

Lightning network keys must stay online permenantly so it's much less secure than a regular custodian like coinbase.

I have to have my mobile phone off at various times during the day - same for any person whose battery goes flat / power outage etc.   At some point you're going to disconnect from the network.

I did have a chuckle at the counter - the trailing white number is intended to be a fraction - which shows my age I can recall motor-vehicles having such a "feature" in their speedometer.

I'm not sure if that means $1000 as a total balance, or the total amount deposited. If it's the latter, you'll reach it eventually even if you only use the wallet for small amounts at a time.

Yesterday, Wallet of Satoshi didn't allow me to send larger amounts: 3000 sat worked, but 4000 sat didn't work. Today it works again.
Those things are annoying, but all the more reason to spread custodial funds over different wallets.

Hmmmm yeah they don't look like a good choice. Honestly custodial wallets for the lightning network seem a bad idea unless you won't be online for 2 weeks.

I just don't want the hassle of opening and balancing channels. Custodial wallets are much easier.

I wonder how BlueWallet for instance secures their funds against theft (because of a bug or hack).
