Key points

  • SoFi says stablecoin settlement is live for its debit and credit card program on Mastercard's network.
  • The bank is migrating a card program with more than $25 billion in annualized volume to settlement using SoFiUSD.
  • Merchants can continue receiving conventional bank funds and do not need to hold stablecoins or build blockchain systems.

SoFi Bank has begun settling debit and credit card transactions with its dollar-backed SoFiUSD stablecoin across Mastercard's global payments network, moving a bank-issued token from pilot-stage infrastructure into live card operations. SoFi said on September 22 that it is migrating its full card program, representing more than $25 billion in annualized volume, to blockchain-based settlement. Barron's and Investor's Business Daily separately reported that the system is operational and processing real transactions.

Settlement changes behind the card experience

The change occurs in the back-end process through which card obligations are settled, rather than at the checkout screen. Consumers can keep paying with SoFi debit and credit cards, while participating businesses do not need to accept or hold SoFiUSD. SoFi says merchants can receive settlement funds in a SoFi Bank account and convert them to cash around the clock, preserving the familiar bank-account experience while using blockchain rails between financial institutions.

That distinction limits what the launch means for everyday users. It does not turn each card purchase into a consumer crypto transaction, and it does not require a merchant to manage wallets or digital-asset price exposure. The intended benefit is faster access to settlement funds and more flexible liquidity management for issuers, acquirers and merchants. Mastercard continues to provide the payment-network framework and controls surrounding the card program.

A regulated bank token with familiar risks

SoFiUSD is issued by SoFi Bank, N.A., a nationally chartered bank regulated by the Office of the Comptroller of the Currency. SoFi describes the token as redeemable one-for-one for U.S. dollars and backed primarily by cash reserves. The bank first opened the stablecoin to enterprise partners in December 2025 and made it available to consumers through its app in May 2026.

The bank label does not make the token equivalent to an insured deposit. SoFi's disclosures state that SoFiUSD is not a deposit, is not legal tender and is not insured by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. Blockchain transfers can also be irreversible, and users may face operational delays, disruptions or permanent loss. Those caveats remain relevant even when the token is used inside regulated payment infrastructure.

From partnership announcement to production use

SoFi and Mastercard announced their stablecoin partnership in March, saying Mastercard's Multi-Token Network would support SoFiUSD and that the companies would explore settlement for SoFi's own card transactions. The September launch converts that plan into a production deployment. Investor's Business Daily described SoFi's card base as a proving ground that could eventually support similar services for other institutions through the company's Galileo technology platform.

The scale matters because stablecoin payment claims have often centered on trials, limited corridors or crypto-native businesses. A card program exceeding $25 billion in annualized volume gives the technology a larger operational test inside mainstream financial infrastructure. The companies have not disclosed how much of that volume has already completed onchain settlement, the blockchains used, or detailed cost and timing comparisons with conventional settlement.

For banks and payment firms, the launch offers evidence that stablecoins can be used as an internal settlement asset without changing what shoppers or merchants see. Its longer-term importance will depend on whether the arrangement delivers measurable savings, reliable liquidity and regulatory compliance at scale. Those results, rather than the token label alone, will determine whether other card issuers follow.
