Mastercard expands settlement support for USDC, PYUSD, RLUSD

Mastercard announced on Wednesday that it will expand its settlement capabilities to allow issuers and acquirers to settle certain card transactions using regulated stablecoins. The move introduces intraday, weekend, and holiday settlement options and supports both fiat settlement and on-chain settlement through tokenized dollars, giving partners more flexibility in managing liquidity and timing.

The company detailed that the stablecoins will include Circle’s USDC, Paxos-issued PYUSD, USDG, and USDP, as well as Ripple’s RLUSD and SoFi’s SoFiUSD. Settlements will be enabled across multiple networks, including Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo and XRPL, expanding the rails for on-chain settlement alongside traditional fiat channels.

Mastercard said that ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei are expected to be among the first to support this optionality for stablecoin settlement in the United States and Latin America. The company also highlighted that this capability comes as it secured a New York BitLicense in May, authorizing its US transaction services unit to conduct regulated digital asset activity in the state.

The development underscores a broader trend of stablecoins moving deeper into mainstream financial infrastructure as major payments networks test tokenized dollars for settlement. It mirrors parallel moves by competitors and partners who are integrating digital dollars into core settlement workflows, signaling a potential shift in how everyday payments and cross-border flows are settled.

Key takeaways

• Mastercard’s settlement expansion enables intraday, weekend, and holiday settlement using regulated stablecoins for card transactions.
• Supported stablecoins include USDC, PYUSD, USDG, USDP, RLUSD, and SoFiUSD, with settlement possible across networks such as Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo, and XRPL.
• Early adopters in the US and Latin America include ARQ, CBW Bank, Cross River, Lead Bank, and Nuvei; the expansion follows Mastercard’s NY BitLicense approval for regulated digital asset activity.
• The move sits within a wider industry push toward stablecoin settlement, including Visa’s own network expansion and rising remittance use cases.
• Market context remains supportive, with the stablecoin sector typically cited around a few hundred billion dollars in value, underscoring the incentive for infrastructure players to embrace tokenized dollars.

Industry-wide momentum behind stablecoin settlements

Mastercard’s initiative arrives as payments networks increasingly test and scale stablecoin settlement to improve liquidity management and settlement speeds. Visa, for one, has reported progress in its own stablecoin settlement pilot, noting that the program reached a $7 billion annualized run rate after expanding to five additional blockchains, bringing its supported settlement networks to nine. The bank network described the expansion as a means to provide issuers and acquirers with more pathways to settle transactions as tokenized dollars become more integrated into everyday payments.

The trend is not isolated to card networks. In the remittance space, stablecoins are being piloted and deployed to streamline treasury operations and currency trading. MoneyGram recently launched MGUSD, a USD stablecoin on the Stellar network, designed to support treasury management settlement and US currency trading ahead of a broader global rollout. On the other side of the ecosystem, Western Union rolled out USDPT, a US dollar-denominated stablecoin, on the Solana network, with initial launches in the Philippines and Bolivia and plans to expand in 2026.

The current appetite for tokenized dollars is reinforced by the overall market size attributed to stablecoins, which has been cited around the $320 billion mark. The convergence of payments networks, remittance corridors, and stablecoins suggests a concerted push toward on-chain settlement as a complementary or alternative path to traditional cross-border rails.

Related industry developments, such as Solana’s collaboration with Mastercard and Western Union on new developer platforms, illustrate how these rails may evolve with broader ecosystems, interoperability, and platform-level tooling designed to accelerate adoption across networks and geographies.

Regulatory context and regional rollout

Mastercard’s NY BitLicense marks a significant regulatory milestone, enabling a regulated digital asset business footprint within one of the largest U.S. markets. The license aligns the company with compliance standards expected by banks, issuers, and merchants, potentially accelerating uptake among firms seeking to leverage stablecoins for settlement in regulated environments. As more jurisdictions weigh stablecoin-friendly frameworks, the balance between innovation and consumer protection will shape how quickly and where these settlement methods scale.

As networks extend stablecoin settlement to more rails and regions, readers should monitor how regional regulators respond to expanding issuance, custody, and settlement activities. The next phase will likely involve more clarity around liquidity requirements, risk controls, and interoperability standards across chains, all of which influence the pace and reliability of cross-border and domestic settlement workflows.

For investors and users, the trend offers a clearer view of where digital dollars could integrate with traditional financial infrastructure. It also heightens the importance for issuers and payment partners to build robust compliance and risk-management processes as more entities participate in regulated stablecoin settlement.

Looking ahead, market participants will be watching how these capabilities are adopted in different regions and how quickly the ecosystem can harmonize on standards that facilitate scalable, compliant, and secure settlement via tokenized dollars.
