Thanks for the highlight! I’m looking forward to going through these. Nice formatting as well. 👍

This is kind of ~meta but mostly Lightning. 

Under my recent post about [<bitcoin-qr />](https://stacker.news/items/737255/r/thebullishbitcoiner), I found this cool [Lightning app template](https://stacker.news/items/72427/r/thebullishbitcoiner) by @reneaaron (from 2022!) that I’m looking forward to checking out.

Just discovered this tool by Brandon Lucas and found it to be very useful. Also, did I mention easy-to-use?

You can find the GitHub [here](https://github.com/thebrandonlucas/bitcoin-qr) and a demo I made (complete with a function to check for payment) on the [Bullish Prototype](https://bullishprototype.vercel.app/bitcoin-qr.html). 👨‍💻

Meme Monday - Best Bitcoin Meme Gets 10,000 Sats

TIL not all Lightning services support LNURL-verify

While I was writing a polling function to verify payments, I came across this error when trying to use a Primal address. 

![](https://m.stacker.news/58698)

I think it’s pretty cool that two of our favorites — @Alby and @sn — support LNURL-verify! Are there any others?

I couldn’t find much on here except that it seems like it wasn’t that popular. Here’s @koob’s comment when it got [merged into LUD-21](https://stacker.news/items/564422/r/shadowstacker):

> I'm surprised. That one received a ton of pushback over ~~the years~~ what feels like years.

Does anyone know why that is?

How to hide “sats stacked” on your profile

Yeah, you’re right. I didn’t think to look at it from another account (or logged out). 🤦🏻‍♂️ 

I’ve come across several accounts that don’t have the total amount of sats stacked displayed on their profile and I can’t find that setting anywhere. Does anyone know how that’s done?

Yesterday I posted about [Lightning Welder](https://stacker.news/items/730371/r/thebullishbitcoiner) without knowing that there needs to be a backend for it to work. [Super turned his off after the BTC++ hackathon](https://stacker.news/items/730371/r/thebullishbitcoiner?commentId=730676), but he graciously took some time to let us know how to run our own.

Wanted to highlight these steps in a separate post in case any of you stackers want to try it out. 

> There is a seven step procedure to run the backend and connect it to the frontend, so I will go over them here
> 
> **First step**
> 
> The first step is something I have to say after the second step
> 
> **Second step**
> 
> The second step is to install LNDK according to the instructions on this page: https://github.com/lndk-org/lndk
> 
> But notice that the page tells you that first you "need a LND node running at least LND v0.18.0...with the peersrpc, signerrpc, and walletrpc sub-servers enabled"
> 
> **First step again**
> 
> So that's the *real* first step: compile LND with those sub-servers enabled by following the guide they link to
> 
> **Note on the first two steps**
> 
> Don't run LND and LNDK as two different linux users like a "good" programmer would do. To control LNDK I opted not to use its api, because I was running out of time, so instead I use the `exec` command to spin up a terminal inside nodejs and interact with it via stdin and stdout. And for one specific LND command ("trackpayment") the LND API wouldn't work for me (I was probably using it wrong) so I use `exec` for that too. Which means you must run the server, LND, and LNDK all on the same linux user -- if you separate them, the terminal won't have the `lndk-cli` and `lncli` commands available, so the program will fail.
> 
> **Third step**
> 
> To run the server, first clone the github and run `npm init -y`.
> 
> **Fourth step**
> 
> Then install the dependencies: `npm i crypto noble-secp256k1 ws browserify-cipher request`
> 
> Also, modify the first few lines of the server.js file so that they contain your LND node's invoice macaroon, admin macaroon (both in hexadecimal format), your LND Rest api endpoint (this is usually https://127.0.0.1:8080), and you can ignore the other four fields -- I intended to use them to let users modify their fee settings and a few other things, but I don't actually use them anywhere in the code, the fees are just hard coded to 10 sats.
> 
> **Fifth step**
> 
> Then run `node server.js`
> 
> It should spit out a nostr public key and then wait for incoming messages
> 
> We opted to use nostr for communication between the frontend and the backend so that anyone can run this without needing to expose ports
> 
> We *intended* to make it so that people running the backend would *announce* themselves on nostr, as well as a fee structure (e.g. do they charge a flat fee for forwarding bolt11 payments to a bolt12? A percentage fee? How much?) and the frontend would *listen* for those announcements and display them to the user. But we ran out of time so we hard coded the nostr pubkey of my backend into the frontend, which is why it stopped working when I turned off my laptop.
> 
> **Sixth step**
> 
> To make sure your service is working, edit the index.html file in my github repo and find the line `welder = "<nostr_pubkey>" and change it to yours. Then open up the index.html file, open up its browser console, enter a bolt12 invoice into the form, and hit enter. You should see a message pop up in your nodejs terminal and you should see the frontend and backend interact. Watch the browser console -- eventually you should see a bolt11 invoice in there. (I don't "pop it up" on the page, it only appears in the console.)
> 
> **Note about the sixth step**
> 
> As @justin_shocknet has always warned, I have found that the onion messaging aspect of bolt12 is very unreliable. About 2/3 of the time, the server will use the lightning network's onion messaging transport layer to reach out to whatever node issued the bolt12 and something goes wrong: the message does not reach the destination or the reply does not reach my node.
> 
> Consequently, most of the time, the service does not work. I find that if, after hitting the "Submit" button on the form, you don't see a bolt11 in your browser console after about 10 seconds, try hitting submit again; and occasionally try restarting all four services: LND, LNDK, and the nodejs file, and the web browser (after entering in your "new" nostr pubkey -- the nodejs service doesn't save it so a new pubkey is created every time you restart the nodejs service).
> 
> Eventually it should work and you should see a bolt11 invoice in your browser console.
> 
> **Seventh step**
> 
> Pay the bolt11 invoice and you should see a corresponding payment show up in your bolt12-supporting wallet.
> 
> **Note about the seventh step**
> 
> I've only tested this with phoenix wallet so it might not work with other wallets. Also, my frontend hard-codes an invoice of 15 sats, and since the server charges a 10 sat flat fee, the bolt11 will be for 25 sats. So don't be surprised when your phoenixd only receives 15 sats even though you paid 25.

How to run Weld and connect it to Lightning Welder

Lightning Welder helps legacy lightning wallets pay BOLT12 offers

Thanks Super! Do you have any documentation on how to get the server up and running?

Yeehaw! LFG! 🤠

This seems pretty cool. Has anyone tried it out yet?
