Mastercard Launches 24/7 Stablecoin Settlement Supporting USDC, PYUSD, and RLUSD on June 3

Mastercard announced on June 3 plans to support 24/7 on-chain settlement using regulated stablecoins, including Circle's USDC, Paxos' PYUSD, and Ripple's RLUSD. The service operates across eight blockchain networks—Ethereum, Solana, Polygon, Base, Arbitrum, XRPL, Canton, and Tempo—enabling settlement on weekends, holidays, and outside traditional banking hours.

Initial rollouts will focus on the United States and Latin America, with early partners including Cross River, Lead Bank, CBW Bank, ARQ, and Nuvei. Mastercard said the expansion improves liquidity management and supports faster payment flows. Jack McDonald, Senior Vice President of Stablecoins at Ripple, stated that the partnership validates blockchain technology for critical payment infrastructure.
