Mastercard starts round‑the‑clock settlement using multiple regulated stablecoins across eight blockchains

Mastercard now supports stablecoin settlement using USDC, PYUSD, RLUSD and four other regulated assets, and will run settlement 24/7 — covering intraday windows, weekends and public holidays across its network. Eight blockchain networks are supported, including Ethereum, Solana, Base, Polygon and the XRPL ^[1].

The rollout adds on-chain settlement capabilities and works with regulated stablecoin issuers — including Circle, Paxos and Ripple — to enable always-on settlement and faster institutional payment rails, a response to growing demand for real-time movement of money ^{[2] [3] [4]}.

The update extends Mastercard’s settlement rails to support regulated stablecoins and round‑the‑clock on‑chain settlement across multiple blockchains, positioning the network to handle intraday and out‑of‑hours fund movements ^{[1] [3]}.
