Mastercard on Tuesday opened its global card-settlement network to regulated stablecoins, allowing issuers and acquirers to clear card transactions onchain across eight blockchains and adding intraday, weekend and holiday settlement cycles for the first time.
The company announced the expansion in a press release from its Purchase, New York headquarters, framing it as a move toward an "always-on" model for rails that today carry roughly a quarter of the world's card spend.
The supported assets are Circle's USDC, Paxos-issued PYUSD, USDG and USDP, Ripple's RLUSD and SoFi's SoFiUSD. They will be enabled across Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo and XRPL.
ARQ — formerly DolarApp — CBW Bank, Cross River, Lead Bank and Nuvei are expected to be the first to use the optionality, starting in the US and Latin America.
Mastercard reported $10.6 trillion in gross dollar volume in 2025, according to its most recent 10-K.
