8/8 So: do stablecoin rails win, or does the 10 years acquirer moat hold? Asking seriously. One of us is right.

1/ Jack’s diagnosis is exactly right. POS is the last payment surface that hasn’t been rethought at infrastructure level. Card rails are still domestic-first with international bolt-ons. His solution keeps Visa.

Every crypto card is a lie. Here's why. 🧵👇

Card tap. Phone tap. QR scan. One terminal. Zero middlemen. Stablecoin payments settling on-chain in seconds, using the same EMV standard every terminal already reads. Built on @base.

@victorzh well done

First integration call with a major payment processor. Their engineers said "adding a new card network requires new development." Actual work: 3 config entries (AID, CA public key, BIN route) and a URL. Acquirers hear "new card network" and think Visa-scale onboarding. Your job @OpenPasskey is to prove it's not.

Three ways to pay. No Visa. No banks. Card tap. Phone tap. QR scan. All settling on-chain in seconds through the same pipeline. Same EMV standard every terminal already reads. Our own IIN from ISO. P-256 cryptography. Fully decentralized. Non-custodial. No middlemen. @OpenPasskey | Built on @base youtu.be/mgDm9kYAw2k

This is not a Visa card. It’s not a Mastercard. It’s our own card, with our own IIN from ISO, running on the same EMV contactless standard. P-256 cryptography. Settles on-chain in seconds. No banks. No card networks. No interchange. Same tap. Different rails. The RBA just banned surcharges. We removed the fees entirely. Built on @base

It takes payment via x402 and MPP as well 👊 physical + digital, human + agent

The x402 ecosystem is growing fast. @CoinbaseDev @stripe @base all building the rails. Builders shipping live services. httpay.xyz is one of the first — ~100 pay-per-call APIs for AI agents. What are you building with x402?

We started OpenPasskey because we saw this gap firsthand. Walked into 100+ cafes in Sydney. Every owner had a drawer of dead loyalty cards and a POS terminal they barely understood. None of them wanted another app. All of them wanted repeat customers. One NFC tap. No card. No app. Loyalty earned onchain. That's the whole product. The Nilson Report is projecting 32B+ cards by 2030. We're betting the next card scheme looks nothing like a card.

💯 A lot of people are “careful” in the wrong direction 😂😂😂

Payments Are Not a Tech Problem. They Are a Value Distribution Problem. linkedin.com/pulse/payments…

“Trading is a feature. Habits are the business.” The next winners won’t be the best markets—they’ll be the best products people use daily.

@ShanAggarwal In 2024, merchants paid a total of US$ 125.87 billion in in-person card payment fees. If we removed banks (issuers), networks (Visa) and older acquirers, that US$ 125.87 billion could be better distributed.

@ShanAggarwal When payments become the on-chain bus, loyalty, marketing, and financing plug in on the same rail. Smart contracts encode the rules and fee splits, routing value back to the participants who create it. Can @base get us there? @ShanAggarwal @sfrankel9 @jessepollak

@OpenPasskey @victorzh @cdixon should have a look.

We’re building OpenPasskey—the card scheme for crypto, like Visa is for fiat. We start in one vertical – cafés – by fixing offline loyalty with an all-in-one NFC terminal and Apple/Google Wallet cards; over time the same hardware and wallet identity give merchants a clean path into on-chain payments in everyday retail. Why cafés first Cafés are the highest-frequency offline retail. And offline loyalty is broken. No one wants another app, QR sign-up, or to say a phone number aloud for a stamp. So we built a small NFC “magic box” + Wallet pass flow. How it works • Customer adds a pass to Apple/Google Wallet • Tap phone to our box → stamp issued or redeemed • Staff press ≤2 buttons • No app, no forms, no POS integration Why it matters Once the tap-for-loyalty habit exists, the same hardware + wallet identity is a clean path to low-fee on-chain payments (stablecoins first). Tap to earn today; tap to pay tomorrow. Payments are the bus that connects business systems. As retail adopts it, blockchains shift from “just a rail” to the integration layer for commerce. Traction (Sydney) • 9 paying cafés live (11 incl. betas) • ~900 consumers • ~9,000 one-tap loyalty transactions to date • First 10 terminals sold out in 10 days • Active onboarding queue; targeting ~20 paying cafés before Christmas • Coinbase Base Batches 02 finalist (top 50/725) What’s next • Install the next cafés in the queue • Add 2–3 device partners to de-risk supply If you care about bringing everyday retail and consumer on-chain, follow along.
