USD-pegged
Each USDC is designed to be redeemable one-to-one for a US dollar, fully backed by cash and short-dated US Treasuries. A stable peg keeps the cardholder's spendable value predictable.
A USDC card program is a card programme where cardholders hold USDC — Circle's regulated, US-dollar-pegged stablecoin — as their spendable balance and pay merchants over the Visa or Mastercard networks. At the point of sale the required amount of USDC is converted to fiat in real time, so the cardholder spends a digital-dollar balance while the merchant is paid in ordinary currency. This guide explains why USDC specifically is used, how settlement and compliance work, and how fintechs and crypto businesses launch one.
The defining feature of a USDC card program is the funding asset. Instead of a fiat current account or a prepaid float, the cardholder's balance is held in USDC, on-chain or in custody, and only converted at the moment of spend. The card itself is an ordinary Visa or Mastercard product, so it works at any merchant that accepts the scheme — there is no special terminal or merchant integration required.
This is the same model described in the stablecoin card entry, with USDC as the specific base asset. The conversion mechanics are covered in more depth under crypto-to-fiat settlement.
USDC is issued by Circle and is one of the two largest dollar stablecoins. Programmes choose it as a base asset for four reasons:
Each USDC is designed to be redeemable one-to-one for a US dollar, fully backed by cash and short-dated US Treasuries. A stable peg keeps the cardholder's spendable value predictable.
Circle publishes regular reserve attestations and operates under recognised regulatory frameworks, which makes USDC easier for licensed issuers and banks to accept as a funding asset.
USDC is natively available across Ethereum, Base, Arbitrum, Solana and Polygon, so cardholders can fund from whichever chain has the lowest fees or where they already hold balances.
Broad exchange and DeFi liquidity means the real-time USDC-to-fiat conversion at the point of sale can be sourced reliably and at tight spreads.
A USDC card program bridges two settlement worlds: the on-chain world where the balance lives, and the card-scheme world where the payment clears. The cardholder experiences a single instant payment, but two flows happen behind it.
On the card side, the transaction follows the standard scheme flow — authorisation, then daily clearing and settlement through Visa or Mastercard, with the issuer debited and the merchant's acquirer credited in fiat. On the crypto side, the program debits the cardholder's USDC at the authorised rate and the program's funding pool covers the fiat obligation to the issuer. Because the conversion happens at authorisation, the merchant and acquirer never touch USDC; they are paid in ordinary currency exactly as for any other card transaction. Programmes typically hold a working fiat float to fund settlement and periodically rebalance it against the USDC collected from cardholders.
Because a USDC card program touches both regulated payments and crypto assets, it sits under overlapping compliance regimes:
A USDC card program lets a crypto-native business give its users a way to spend digital dollars in the real world without first off-ramping to a bank account. For the operator this means:
Launching a USDC card program from scratch — securing scheme membership, a BIN, crypto custody and the conversion engine — is a multi-year, multi-licence undertaking. Most operators instead build on a white-label stack that already has these pieces certified, and integrate against an API.
Codego operates USDC and stablecoin card programmes across seven regions — the EU, US, UAE, Asia, Africa, LATAM and Oceania — with Apple Pay and Google Pay support and revenue share for partners. The product side is documented under white-label crypto cards and the broader card issuing platform, and the technical integration is described in the Visa crypto card API documentation. A typical launch covers cardholder onboarding and KYC, USDC funding and custody, real-time conversion, card creation and fulfilment, and authorisation and settlement webhooks.
