@victorzh yes, works 99% crypto wallets out of box.

Designing a < $50 crypto payment terminal. ERC-681 QR, any wallet, any ERC-20, non-custodial — each invoice gets a one-time address, so the terminal can't spend your revenue. ~$0.002 per payment on Base. Card schemes charge 1.5–3% for the same job.

Want one?

"Any wallet" includes this one. The PAN points at the wallet, the wallet never owns the PAN. Right way round. And since the PAN is an NFT, TokenScript renders it as a usable object, not a 16-digit string.

[victorzh.eth @victorzh]

A bank card welds the number, the chip, and the account into one thing. @OpenPasskey split them.

Own your PAN. Bind it to any card or phone. Point that at any wallet. Re-link whenever.

The number outlives the card. The card outlives the wallet.

Who wants 6690 8200 0777 7777?

AUDM @Macropod_AU retail payment went live in a Sydney café this week. Scan, pay, merchant has bankable AUD almost instantly.

The rail underneath isn't the token. @OpenPasskey settles stablecoin in 1 second on Base, 0% protocol fee, no card network in the path.

Same rail a person taps, an agent pays over x402/MPP. One settlement layer for human and machine money.

AUD stablecoin payments, settling on Base 🇦🇺

[victorzh.eth @victorzh]

The QR, explained.

It's a plain ERC-681 URL (Not reinventing the wheel). ethereum:<token>@<chain>/transfer with the amount and a receiving address. Every major wallet already reads this format, so any wallet scans and pays.
Nothing custom to install.

The receiving address is single-use. The terminal derives a fresh one per invoice with CREATE2, so no two payments share
an address and nothing is reused. The customer's wallet sends straight to it, then the funds sweep to the merchant vault.

No new app, no new account, no new card. Just a scan.

The phone tap, explained.

On Android we use Host Card Emulation. The phone presents the same EMV card over NFC, no card needed in hand.

On iPhone the secure NFC path (NFC SE) needs an Apple entitlement. We've applied. Not expecting it soon, Apple moves slowly here.

We've also applied to Apple Pay and Google Pay. Same story, long queue. We're not waiting on either. The QR and card
paths already work on every phone today.

What does Australia's first retail payment in AUD stablecoin look like? A Sunday lunch at a Sydney Malaysian takeaway.

Card tap, phone tap, or QR from any wallet. Customer pays @AUDD_digital, merchant keeps it or cashes out to AUD.

No Visa. Settled on @base in seconds.

[victorzh.eth @victorzh]

I know celo since 2019 while we were building @AlphaWallet I remember we are also one of the Celo Alliance members. To do local retail payments, we need to work with locally regulated local currency stablecoins which holds local licenses and provide easy minting and redeeming for locals. Different requirements compared to dex trading.

8/8 So: do stablecoin rails win, or does the 10 years acquirer moat hold?

Asking seriously. One of us is right.

[victorzh.eth @victorzh]

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

[victorzh.eth @victorzh]

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.

[victorzh.eth @victorzh]

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 @OpenPasskey]

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.
