Overview
- Mastercard announced the new settlement framework on Wednesday that will add regulated stablecoins and on‑chain settlement capabilities to its existing fiat settlement network.
- The company named initial supported stablecoins as USDC, PYUSD, USDG, USDP, RLUSD, and SoFiUSD and said those assets will be usable across multiple blockchains including Ethereum, Solana, Polygon, Base, Arbitrum, and XRPL.
- Early participants listed by Mastercard include Cross River, Lead Bank, CBW Bank, ARQ, and Nuvei, and the firm said deployments will begin in the United States and Latin America.
- The new plumbing will run alongside current fiat rails and adds intraday, weekend, and holiday settlement windows so issuers and acquirers can move liquidity and settle card flows on‑chain outside normal banking hours.
- Payments firms and banks see this as a push to use stablecoins for treasury operations and faster cross‑border settlement, and the rollout will be watched for regulatory approvals, broader partner adoption, and expansion to more regions and networks.
