I'm stoked for farmers, ranchers, and business owners to start accepting Bitcoin as money.

Of course, in the traditional sense, I could buy some goods at a farmers market stall with sending sats from my wallet to their wallet, if they accept Bitcoin.

But there isn't a dedicated Bitcoin POS that these businesses could use.

That's why I created Plaza BTC. It's a sovereign non-custodial Bitcoin Point of Sale in your pocket. An app. Connect your wallet or self-host and start accepting sats in person. Track your sales and inventory. Own your business's identity and data with Nostr log-in. For customers, it's a discovery map to find Bitcoin Businesses to use your sats to purchase goods.

I wanted the Bitcoin Circular Economy to exist in the Bay Area in California, so I went out of my way to create these sovereign tools for businesses to use.

Steak N Shake is a dope pioneer with accepting Bitcoin (I wonder what POS they're using lol). Square is kinda there, but they custody your Bitcoin if you use it. Whereas, with Plaza BTC, you custody your own Bitcoin as the sats always land in your wallet. It's designed this way on purpose.

Own your money. Own your identity. Own your data. Own your business.

Download Plaza BTC on ios or Android. Start accepting Bitcoin for your business in person.

I will buy bottles of Peony Lane Wine in person if you start using Plaza BTC and if you give me your feedback on it.

Peace

thats so sick! I love to see more bitcoin only businesses. im definitely down to cop some raw honey and spend some sats.

also, i made something for you and for all bitcoin businesses. i created a sovereign noncustodial bitcoin lighting point of sale app. if you ever sell your honey in person at farmers market or something, you now have a full Bitcoin POS in your pocket. It's called Plaza BTC and its live on the ios app store, google play store, and zapstore. its free and has zero fees forever. that way more and all sats go to your wallet. i think we're all sick of fees and having a 3rd party hold our money and even having to wait to receive your money from them is insane or even having to pay more fees to get it lightning quick. what i created routes around all of this. sorry square @Block Open Source lol

This is a good question. Let me separate two things it runs together.

Custodial means a third party holds your funds and can move them without you (and can lose them, freeze you, or get hacked). Noncustodial means you hold the keys and the funds. With NWC you point Plaza at your own wallet. The sats are received and held there. Plaza never takes custody, never sees your keys, can't move your money, and the connection is scoped to specific permissions and revocable at any time. So in the precise sense of the word it's noncustodial, and that's true whether the client is open or closed.

Now the fake QR attack you describe is real, but it's an integrity concern, not a custody one. Here's why it doesn't break custody. The invoice is minted by your own wallet via NWC, and your wallet, not the app, is the source of truth on whether it was paid. If a malicious POS showed an attacker's invoice instead, that invoice would never settle to you: lookup_invoice returns unpaid, your balance doesn't move. The theft is immediately visible at the wallet. The screen was never the authority; your ledger is. (It's also not unique to Plaza. A compromised Square terminal could misdirect a payment too. The universal fix is the merchant verifying receipt, which NWC makes trivial.)

And here's the part worth sitting with: open source alone wouldn't actually prevent substitution. Unless you compile it yourself or verify a reproducible build hash against the source, the binary from any app store can differ from the published code. So "closed source equals custodial" collapses two separate questions, custody of funds and integrity of the client, into one. They aren't the same.

What actually shrinks integrity trust: open protocols you can inspect on the wire and swap clients on, reproducible builds you can verify, and a design that keeps the wallet as the source of truth so tampering is detectable. Plaza runs on open protocols end to end (Lightning, Nostr, Blossom), so you're never locked into my client. Point that same NWC connection at any compatible POS and your wallet behaves identically.

Happy to walk the full NWC invoice flow if you want to poke at it.

"Normal and boring" is the right bar. When the kid at the register doesn't even notice, you've basically won.

But the only custodial part of what you described was the rails underneath, not the experience on top. Square bundled those together; they don't have to be. You can get the exact same tap-and-go with the sats landing straight in your own wallet, nothing to convert, nobody in the loop who can flip the toggle off.

That 5% you go custodial on for convenience is exactly the gap I built with Plaza to close — a non-custodial Lightning POS that feels just as boring and normal, except it's your keys. Makes the whole 100% p2p.

You clearly get it, so I'd value your read. plaza btc live on the ios app store and the @Zapstore for android
