Ok. So. Where does this live? I mean. Is this an invoice? I see your profile, so how did you organise it? I see some text about getting your own page… I also see that I need a lightening wallet. I would need to download one then. Is the list of wallets in the drop down the only choices? So this is not attached to the primal wallet? I know dumb questions. Feel free to pass.
You input your npub and it gives a page that you can link to from other places on the web. On the page, the user can select how many coffees to zap you in thanks for whatever nice thing you did or just to show support. 1 coffee is like 2,880 sats.
I just put my npub in. You can try it 👇

You don’t need to do anything. It just works. Just link to your page and you’re done.
Link to what page? Also I just got zapped 2873 sats which I am presuming came from my playing with your app but I didn’t request it. There is a receipt but it does not tell me where/who the sats came from. When I clicked default wallet it open Muun which I forgot I had and have never used. I thought it would open my primal wallet.
This page is for linking to others so they can pay you.
You can also pay them on their pages by copying invoice or opening in a wallet. You can set default to primal if that’s what you use.
You got some sats because I zapped you a coffee ☕️. Enjoy!
Ok. I have to let this sink in (I don’t quite get it but I am trying). I will fiddle around with it and see if I can make it click. Crazy that you can just send me sats like that! My address must be visible somewhere? Jeesuzz I have sooo much to learn about this protocol. 🤯
Since I know your npub, I know your lightning address as it’s stored on relays. I can fetch the lightning address and use it to generate an invoice. 🧾
Please don’t use the ₿ symbol for sats.

a two thousand Bitcoin coffee? and here I thought Starbucks was expensive 😆
Haha, I was confused by that too!
And just a friendly tip: if you must use the Bitcoin symbol (B), make sure the decimal placement is correct! Other example: 1$ ≠ 0,01$
