Pay with your crypto wallet. Or with the OPK card.
Walk into a café in Sydney. Pay with AUDD/AUDM from MetaMask, Base App, or any crypto wallet — by scanning a QR. Or order the OPK card and tap-to-pay anywhere a regular card works. No new app to learn. No extra KYC. Just your existing wallet.
Use what you already have. Or get the card.
Pay from your existing crypto wallet
Open camera. Scan the QR at the merchant. Your default crypto wallet app pops up. Confirm TX. Done in 3 seconds.
- AUDD, AUDM — pick your stable
- Works with any EIP-681 compatible wallet
- No app install. No account. No KYC.
- Merchant gets settled in fiat — you stay in crypto
The OPK card — physical & digital
A single card backed by your self-custodied stablecoins. Tap it at any OPK-accepting terminal. Spend stablecoins like cash, get OPK rewards, keep custody — without ever touching Visa or Mastercard rails.
- Tap-to-pay at any merchant terminals
- Self-custody — your keys, your stables
- No interchange, no scheme fees, no FX markup
- OPK rewards, not only reward points, own the network as well
OPK is its own card scheme — not Visa, not Mastercard. Acceptance grows merchant-by-merchant and/or acquirer-by-acquirer. Apple Pay / Google Pay are not on the near roadmap.
Same checkout you already know. Nothing new to learn.
Tap a card, tap a phone, or scan a QR — the exact muscle memory you use every day. The terminal looks identical, the gesture is identical. The only thing that changes is what's underneath.
The OPK card.
First 5,000 cardholders.
The OPK card launches publicly in Q4 2026. Until then, we're issuing 5,000 cards in waves to the waitlist — Sydney first, then AU-wide, then Singapore. No fee to join. We email when your wave is up.
OPK is its own scheme. Apple Pay / Google Pay tokenization is not on the near roadmap.
Pay like cash. Earn like crypto.
Pays like cash
Settled, final, in two seconds. No three-day “pending”. No reversal months later. The merchant has your money. You have your receipt. That's it.
No extra KYC
Your wallet is your identity. Pay from MetaMask, Phantom, Coinbase Wallet — no new account, no ID upload, no verification email. Privacy is the default.
Programmable rewards
Every payment fires an on-chain hook. Issuers, merchants and integrators each plug in their own rewards logic — stamp cards, NFT drops, milestone rebates — minted to your wallet, the moment you tap. No annual fee.
Self-custody
Your stables stay in your wallet. We don't hold them. Lose your card, freeze it, mint a new one. The keys never leave your phone.
AUD-native, not USD-translated
AUDD and AUDM are AFSL-regulated AUD stablecoins issued in Australia. Pay an AUD merchant in AUD. No FX. No conversion fee. No bank in the middle marking up your dollar.
Two-second settlement
The receipt prints before you've put your phone away. Base L2 sweeps your payment to the merchant's ClearingVault in ~2 seconds. No three-day pending. No reversals.
Same card chip. Better cryptography. No middlemen.
OpenPasskey is its own card scheme. Same EMV chip and secure element as Visa — but the message terminates on Base L2 instead of a card network. The acquirer routes our IIN, the merchant gets AUD, you keep custody of the stablecoin.
The stack, plain English
Skip the queue. Get a card.
Public launch is Q4 2026. Waitlist is open today.
