Overview
- Mastercard announced on Wednesday, June 3, 2026, that it is rolling out network‑level support for on‑chain settlement using regulated dollar stablecoins and new intraday, weekend, and holiday settlement windows.
- At launch the network will accept six regulated stablecoins — USDC, PYUSD, USDG, USDP, RLUSD, and SoFiUSD — and will route settlement across eight blockchains including Ethereum, Solana, Polygon, Base, Arbitrum, the XRP Ledger, Canton, and Tempo.
- Mastercard said the stablecoin option will run alongside existing fiat settlement rails and will keep current security, fraud protections, and dispute processes in place so issuers and acquirers can choose which settlement path to use.
- Initial deployments will begin in the United States and Latin America with early participants named as ARQ, CBW Bank, Cross River, Lead Bank, and Nuvei, and Mastercard’s U.S. subsidiary MTS US holds a NYDFS BitLicense to support related activity.
- The expansion builds on Mastercard’s broader push into regulated digital‑asset infrastructure, including its March agreement to acquire BVNK, and could speed cross‑border payments and cash‑flow management for merchants and treasuries while remaining subject to further regulatory approvals.
