Mastercard is opening a card-settlement network to regulated stablecoins and planning on-chain clearing across eight blockchains, the payments giant said Wednesday. The goal is straightforward. Card issuers and acquirers can clear card transactions directly on-chain instead of only through traditional rails.
This is not a general “stablecoins for everything” pitch. Mastercard frames it as settlement infrastructure tuned for timing and liquidity, and it is pairing the blockchain expansion with new settlement cycles. It also stressed that deployments will run under regulation.
Eight blockchains, “regulated stablecoins” only
Mastercard said its service will support stablecoins issued by several recognized providers, naming Tether’s rival Circle and its USDC. It also pointed to USDC “already supporting early on-chain settlement activity” in select markets.
The company’s initial listed lineup also includes Paxos stablecoins, including PYUSD, USDG, and USDP. Mastercard added Ripple’s RLUSD and SoFi’s SoFiUSD.
On the network side, Mastercard said the stablecoins will be enabled across multiple blockchains and listed Arbitrum (ARB), Base, Canton, Ethereum (ETH), Polygon (POL), Solana (SOL), Tempo, and the XRP Ledger (XRPL). Mastercard did not explain how it picks which assets and networks qualify beyond its “regulated” framing.
Same settlement for cards, plus digital-asset settlement
Mastercard said the approach lets customers use both traditional payment settlement and digital-asset-based settlement through the same infrastructure they use today. It did not describe changes to which kinds of partners can use the network.
That matters because settlement is where operational friction shows up first. If Mastercard can run on-chain settlement alongside legacy systems through the same platform, it lowers the integration burden for partners who want stablecoin settlement without swapping out their core card workflows.
Intraday, weekend, and holiday cycles
Beyond adding more chains and stablecoins, Mastercard plans to introduce intraday settlement cycles plus weekend and holiday settlement options.
In an interview comment included in the announcement, Raj Dhamodharan, executive vice president of Blockchain and Digital Assets at Mastercard, said the “next stage of stablecoin adoption” is about practical use cases where timing and liquidity matter. He pointed to settlement directly and described intraday and weekend options as a liquidity management tool for partners in an always-on digital economy.
That is the practical angle here. Card settlements have schedules. Digital assets do not. Faster cycles are meant to reduce the gaps where liquidity can idle or get stuck waiting on traditional settlement windows.
Rollout window is the constraint
Mastercard said the expanded capabilities will roll out globally “subject to regulation.” For now, it limited the initial deployment to “parts of the United States and Latin America.”
The company also said it plans to add additional regions, partners, and regulated stablecoins through 2026 as the offering expands beyond those initial rollout areas.
So the headline expansion comes with a geofenced start and a compliance gate. That likely slows adoption compared with pilots that can move quickly, and it sets expectations that stablecoin settlement will grow in phases rather than in one leap.

The risk is still regulatory and operational
Mastercard’s move leans on regulation as the filter. That implies partners still face compliance work around custody, issuance standards, and acceptable on-chain rails in each jurisdiction.
It also does not eliminate execution risk. On-chain settlement depends on stablecoin availability, network performance, and integration correctness across multiple chains. Mastercard may reduce friction by using one infrastructure layer, but it still adds complexity versus a single legacy settlement pipeline.
For now, the company has outlined the “where” and “what assets” at a high level. The practical question for partners will be how quickly Mastercard’s regulated stablecoin access expands beyond the initial regions and which integrations are ready to handle intraday and non-business-day settlement without bottlenecks.
