How Stablecoins Are Transforming Global Payment Infrastructure and Retail Finance
South Korea's largest crypto exchange operator Dunamu has signed a strategic partnership with Visa to develop stablecoin-based payment rails, cross-border remittance channels, and AI-driven financial products, according to reporting from The Block.

The deal marks another step in how settlement infrastructure built around tokenized dollars is moving from pilot decks into live merchant and consumer flows.
Card-spending trajectory picks up speed
The timing lines up with a measurable shift in retail demand. As PaymentsJournal reports, monthly crypto card purchases have now crossed the $1 billion threshold, driven largely by stablecoin-funded transactions. The forward curve looks steeper: Tekedia cites projections of stablecoin card spending quadrupling to roughly $50 billion annually by 2028 as merchant acquisition and issuer integration accelerate across major networks.
That pairing — a global card brand signing a regional exchange operator and a nine-figure monthly run rate — is the detail that matters for traditional finance desks. Stablecoins are no longer a settlement curiosity sitting on a roadmap slide; the rails are being wired at the acquirer level.
What to watch on the TradFi side
Two operational items deserve attention. First, which stablecoin actually clears volume. Dunamu has indicated that Open Standard's OUSD is among the tokens being evaluated for potential integration. If a regulated Korean venue ultimately routes card and remittance flows through a specific issuer, that becomes a meaningful distribution channel and a reference point for parallel deals in other markets.
Second, the central bank backdrop. As Demócrata notes, digital money — including instant payment systems, the digital euro, and stablecoins — has moved onto the agenda of central bank discussions. For banks and processors, that translates into concrete compliance questions: which tokens pass KYC, which settle on regulated infrastructure, and which will be accepted by correspondent partners. Those answers shape the cost of cross-border friction long before any consumer-facing product ships.
The practical takeaway is direct. Stablecoins are entering the procurement lists of the same institutions that already run the card and remittance networks. The next quarters will show whether the $50 billion 2028 projection is conservative or optimistic — and whether legacy issuers are acquiring, partnering, or building in parallel to defend their settlement margin.
