SoFi has moved its whole card programme onto a stablecoin its own bank issues, and has not said which chain it runs on

What happened

SoFi said on 22 September that "stablecoin settlement is now live across SoFi Bank, N.A.'s debit and credit card program" on Mastercard's network, and that the bank "is migrating its entire $25 billion card program to stablecoin settlement of transactions using SoFiUSD". The release states that "transactions are live on the blockchain today". Settlement is the leg on which funds move between the issuing and acquiring sides of a card transaction, so what has changed is not what a cardholder does but what moves behind the transaction and when. The operational claim the release makes is about merchants: they receive settlement funds in SoFi Bank accounts and can "withdraw to cash around the clock and at zero cost". SoFiUSD is described as "a payment stablecoin issued by SoFi Bank, N.A., a U.S. national bank regulated by the OCC", "fully redeemable 1:1 for U.S. dollars and supported by reserves consisting primarily of cash", and the company calls it "the first stablecoin issued by a nationally chartered bank". Anthony Noto, SoFi's chief executive, is quoted saying that "in six months, SoFi and Mastercard took stablecoin settlement from an idea to a live product that materially improves how money moves for businesses", and Sherri Haymond, Mastercard's global head of digital commercialisation, that "stablecoins become meaningful when they solve real problems that businesses face every day". The two companies say they "will also explore additional opportunities for SoFiUSD settlement on Mastercard's network, including cross-border payments, remittances and other money movement use cases". The release puts the group at 15.8 million members and 134 million global accounts served through SoFi Tech Solutions. It follows Mastercard's extension of settlement to named stablecoins on 3 June 2026, which this site recorded at the time and which listed SoFiUSD among the tokens covered and eight blockchains among the networks.

Why it matters

This is the version of a stablecoin that pays nobody anything, and it is worth setting beside the two other stablecoin stories of the same day. There is no yield here, no distribution fee and no incentive on balances: the token exists to move value between a bank and a merchant faster than the banking day allows, and the economic claim made for it is same-day availability at no withdrawal cost rather than a return. That is close to the use the euro area's central banks say a currency-referenced token should have and only that use, and it arrives from a bank rather than from a non-bank issuer. The charter is what makes it structurally different from the rest of the field. Because the issuer is the national bank itself rather than an affiliate, one regulated depository is the issuer of the token, the holder of the reserves and the institution the merchant is paid into, and the reserves are described as primarily cash rather than as a securities portfolio. That collapses into one balance sheet a chain that elsewhere runs across an issuer, a reserve manager, a custodian bank and a settlement bank, which is a reduction in the number of counterparties rather than in the amount of risk, and it is the arrangement the ESCB's response contemplates when it discusses banks issuing e-money tokens on their own balance sheets. Scale is the reason to take a settlement change seriously. A card programme the company puts at $25bn of annualised volume is not a pilot, and moving all of it rather than a tranche is a statement that the rail is being treated as production infrastructure. Mastercard's own settlement expansion in June made this possible for several tokens at once, so the interesting number over the next year is how many issuers use it rather than whether one does.

What is not settled

The release does not name the chain. It says transactions are on the blockchain today without saying which blockchain, and Mastercard's June expansion covered eight of them, so the network on which a national bank now settles a $25bn card programme is not public. Nor is it stated whether settlement runs on one chain or several, or what happens to a settlement instruction if that network stops producing blocks. The figures are the company's and are not all of the same kind. The $25 billion is described as the size of the card programme being migrated and as annualised volume rather than as volume settled in the token to date, and no figure is given for SoFiUSD in issue, for reserves, or for the share of the programme already running through it on the day of the announcement. "Migrating" and "now live" are both used, and the release does not say whether the migration is complete. The reserve description is loose in one place that matters. "Reserves consisting primarily of cash" leaves the remainder unspecified, and for a token issued by the bank that holds the deposits it is not stated whether those reserves sit as central bank balances, as deposits elsewhere, or as securities. The next steps named, cross-border payments and remittances, are described as opportunities to explore and carry no date.
