Mastercard announced on June 3 that it is expanding settlement across its global payments network to support regulated stablecoins alongside fiat. Six regulated stablecoins are supported at launch, including PayPal USD (PYUSD), alongside USDC, USDG, USDP, RLUSD, and SoFiUSD. The enhancements add intraday, weekend, and holiday settlement, letting issuers and acquirers settle outside standard banking hours. Settlement runs across eight networks, including Ethereum, Solana, Polygon, Base, Arbitrum, and the XRP Ledger, plus Canton and Tempo.
