Mastercard Expands On-Chain Settlement to Include USDC, PYUSD, and RLUSD Across Six Blockchains
Mastercard has made its biggest move yet into the digital asset space, announcing on Wednesday that it will expand its settlement capabilities to support regulated stablecoins across multiple blockchain networks. The payments giant will now allow its network partners to settle transactions using Circle’s USDC, Paxos-issued stablecoins (PYUSD, USDG, USDP), Ripple’s RLUSD, and SoFi’s SoFiUSD.
This is not a pilot program or a limited test. Mastercard is integrating stablecoin settlement as a permanent, production-ready feature that processes alongside its existing fiat settlement infrastructure.
Six Blockchains, Five Stablecoins
The expansion covers six blockchain networks: Ethereum, Solana, Polygon, Base, Arbitrum, and the XRP Ledger. Mastercard said the multi-chain approach was deliberate — designed to give its partners maximum flexibility in choosing the settlement rails that best suit their operational needs.
“The future of payments is multi-rail,” a Mastercard spokesperson said. “By supporting regulated stablecoins across a variety of blockchain networks, we’re enabling our partners to settle in the way that works best for their business — whether that’s on Ethereum for programmability, Solana for speed, or XRPL for cost efficiency.”
The initial rollout will focus on USDC, which has already been supporting early on-chain settlement flows in select markets. Paxos-issued stablecoins — including PayPal’s PYUSD — will follow shortly, along with Ripple’s RLUSD and SoFiUSD.
Always-On Finance: 24/7/365 Settlement
One of the most significant aspects of the announcement is the operational change it represents. Traditional settlement systems are constrained by banking hours, holidays, and weekends. Mastercard’s stablecoin settlement operates 24 hours a day, 365 days a year.
This “always-on” capability is a major upgrade for financial institutions that have grown frustrated with the limitations of traditional settlement windows. A cross-border payment initiated on a Friday evening, for example, would typically not settle until Monday morning. With stablecoins, that same transaction can settle in seconds or minutes — regardless of the day or time.
“Always-on finance is not a convenience feature — it’s a structural improvement to how money moves,” said Raj Dhamodharma, Mastercard’s Head of Crypto and Blockchain. “When settlement can happen any time, liquidity management transforms. Capital doesn’t sit idle waiting for Monday morning.”
What This Means for Stablecoin Adoption
Mastercard’s move is widely viewed as the most significant institutional endorsement of stablecoins since the asset class emerged. While major companies have held stablecoins on their balance sheets and crypto-native firms have used them for years, Mastercard’s integration brings stablecoins into the heart of the global payments infrastructure.
The network processed over $9 trillion in transactions in 2025. Even a small percentage of that volume settling via stablecoins would represent a massive increase in on-chain transaction activity.
Industry analysts were quick to note the significance:
“Mastercard just legitimized stablecoins in a way that no regulatory framework ever could,” said one DeFi researcher. “When the second-largest payments network in the world says ‘we accept these as settlement assets,’ every bank on the network has to take them seriously.”
A Win for Regulated Stablecoins
Mastercard’s decision to exclusively support regulated stablecoins — those issued by entities subject to US and international regulatory oversight — sends a clear signal about which projects it considers institution-ready. Unregulated, algorithmic, or offshore stablecoins were notably excluded.
This distinction is particularly relevant as the Clarity Act works its way through the US Senate. The legislation, which includes provisions for stablecoin regulation and yield rules, would create a formal federal framework for dollar-denominated digital assets. Mastercard’s move could be interpreted as a vote of confidence that this regulatory clarity is coming.
Competitive Implications for Visa and PayPal
Mastercard’s announcement puts pressure on its competitors — particularly Visa, which has been testing its own stablecoin settlement capabilities but has not made a similarly broad commitment. PayPal, which launched its own PYUSD stablecoin in 2023, is a beneficiary of the announcement since PYUSD is among the supported assets.
“The stablecoin settlement wars are heating up,” said one payments industry analyst. “Whoever gets this right first captures mindshare with the banks and fintechs that will drive the next decade of payment innovation.”
