Mastercard is expanding its on-chain settlement network to support stablecoin transactions, aiming to move funds around the clock through blockchain-based settlement rails. The payments giant has announced integrations with Paxos, Fiserv, and PayPal as it builds stablecoin-enabled settlement infrastructure for institutional payment flows.
The network focuses on the back-end movement of funds, rather than a consumer-facing product change. Merchants, banks, and payment processors can still operate through familiar payment channels.
In this model, counterparties move value as stablecoins on blockchain networks. That structure can shorten settlement times compared with systems that depend on banking hours.
Traditional card settlement often involves several intermediaries and can take one to three business days. By contrast, stablecoin settlement can support near-instant finality. That change matters most for institutions that manage liquidity across markets and time zones. A transaction can reach finality on weekends or holidays without waiting for banking windows.
“At ARQ, stablecoins have been core to our infrastructure from day one. They’re how we deliver real-time, cross-border financial solutions at a fraction of traditional costs,” said Álvaro Correa, co-founder and chief operating officer at ARQ. “Partnering with Mastercard to enable on-chain settlement is a major step toward building the financial infrastructure we envision for the Americas,” Correa added.
Mastercard’s push positions stablecoins as a payment infrastructure, not a speculative crypto product. The focus remains on operational efficiency for institutions already using its settlement network. “As demand grows for faster and more flexible movement of money, organizations are increasingly seeking infrastructure that can operate beyond traditional banking hours,” said Kash Razzaghi, chief commercial officer at Circle.
“Mastercard’s expanded settlement capabilities help meet that need, offering greater choice in how value is transferred and settled,” Razzaghi said. The company’s partner list points to an ecosystem strategy. Paxos brings stablecoin issuance and custody, Fiserv connects bank and merchant technology, and PayPal adds consumer and merchant payment flows.
Cross River also linked the expansion to the demand for faster settlement. Luca Cosentino, head of on-chain finance at Cross River, said partners increasingly want more transparent settlement. “Stablecoins have emerged as a powerful tool to meet that need,” Cosentino said. He added that Mastercard’s move supports digital asset rails alongside traditional payment infrastructure.

The 24/7 settlement feature stands out, as traditional banking systems operate on fixed schedules. Continuous settlement can reduce the amount of capital institutions keep aside for timing gaps. For cross-border payments, the change can reduce delays caused by time zones, banking holidays, and correspondent banking networks. Payment partners and acquirers may gain faster access to funds.
Even so, adoption will depend on banks, merchants, and payment partners integrating with the new rails. Stablecoin rules also differ across jurisdictions. Near term, the impact will likely center on Mastercard’s institutional partners and large payment processors. Broader merchant and consumer benefits will depend on whether faster payouts and lower settlement costs are passed through the payment ecosystem.
Mastercard’s stablecoin settlement expansion shows how blockchain rails can support faster institutional payments. With Paxos, Fiserv, and PayPal involved, the network targets 24/7 settlement, quicker fund finality, and reduced reliance on traditional banking windows across global payment flows.
