SoFi Partnership with Mastercard Demonstrates Stablecoins as Alternative Blockchain Settlement Rail
This year, SoFi announced it is migrating its entire debit and credit card program to settlement via its stablecoin SoFiUSD in partnership with Mastercard, expecting to process over $25 billion in annualized transaction volume. This move does not remove traditional payment ecosystem players like banks and card networks, but provides an alternative blockchain-based rail for settling obligations between parties. Incorporating stablecoins into payment flows enables faster settlement and round-the-clock money movement without changing the cardholder experience.
SoFi’s Move to Blockchain Settlements with SoFiUSD Stablecoin
SoFi recently began settling debit and credit card transactions with Mastercard using its SoFiUSD stablecoin, migrating its entire card program to this system. The bank expects the program to process over $25 billion in annualized transaction volume.
A SoFi spokesperson emphasized that the shift does not remove traditional intermediaries such as banks and card networks. Instead, it introduces an alternative blockchain-based settlement rail for obligations between parties.
For customers, the change is seamless; cardholders continue using their debit and credit cards as usual. Moving settlement onchain allows the bank to accelerate transaction finalization.
Stablecoins Don’t Remove Payment Intermediaries
Experts and Federal Reserve researchers note that while stablecoins can alter payment economics, they do not eliminate banks or payment intermediaries.
Martins Benkitis, CEO of Gravity Team, stressed that Visa, Mastercard, and banks remain central participants: the networks continue to calculate obligations, manage transactions, and coordinate participant interactions.
Payment stablecoins may facilitate inter-institution transfers while staying largely invisible to end-users and businesses, who primarily value reliable and timely settlement.
The Economics of Faster Settlement
Venture capitalist Varun Datta points out that continuous blockchain settlement could reduce delays and the capital companies must reserve across geographies, especially for cross-border payments.
However, higher speed does not automatically mean cheaper end-to-end payments. Costs like currency conversion, regulatory compliance, integrations, and stablecoin management persist.
Datta seeks substantive evidence of lower total costs and improved liquidity management at scale before endorsing the economic case for blockchain settlements.
The Need for Local Liquidity to Finalize Payments
Dollar-denominated stablecoins enable rapid value movements between accounts, yet payments in emerging markets, with thinner local liquidity and fewer banking corridors, remain challenging.
Benkitis noted that final payment settlement requires access to local currency liquidity and domestic banking infrastructure.
Thus, stablecoins speed value transmission, but finalizing payments still depends on traditional banking systems and local liquidity availability.
Why it matters
The news about SoFi’s adoption of its SoFiUSD stablecoin for settling debit and credit card transactions demonstrates how blockchain technology and digital currencies can effectively integrate with existing payment infrastructures to enhance transaction settlement speeds without displacing key market players — banks, card networks, and service providers. This confirms that decentralized solutions do not necessarily aim for full disintermediation, but can act as alternative rails to traditional clearing channels. Such innovations have the potential to reduce costs and accelerate both international and domestic payments while preserving the familiar consumer experience. Furthermore, this case highlights the essential role of local currency liquidity in completing payments, which limits outright replacement of banking services by stablecoins in certain regions.
