Visa and Mastercard Partner with Circle on Stablecoin Blockchain Project

Card networks Visa and Mastercard have announced a collaboration with cryptocurrency firm Circle to support the development of Arc, a new blockchain initiative designed for financial markets, real-time payments, and agentic commerce. The joint release issued on Wednesday confirms that both major payment processors intend to work alongside Circle as it expands its stablecoin ecosystem capabilities.

The partnership underscores a strategic shift among traditional card issuers who previously viewed digital currencies with caution due to concerns over disruption from new-age alternatives. However, recent developments indicate that these networks are now actively seeking opportunities within the evolving landscape of stablecoins rather than resisting them. Visa, identified as the largest U.S. card network, and its competitor Mastercard have expressed eagerness to integrate into enterprises focused on digital currency innovation.

Jorn Lambert, Chief Product Officer at Mastercard, stated in the official release that the future movement of money will not be defined by a single rail or form of value. He emphasised that as stablecoins enter real-world payments and treasury flows, Mastercard aims to assist customers in operating across an increasingly diverse ecosystem. This sentiment aligns with comments made last week by Ryan McInerney, CEO of Visa, who described the company’s forward-looking approach as remaining multi-coin and multi-chain. McInerney told analysts during a July 28 earnings webcast that their role is not to select winners but to help clients connect securely to whichever stablecoins gain adoption.

The regulatory environment has also played a significant part in driving this activity. The passage of the Genius Act last year marked the first government effort to create infrastructure for stablecoin usage, unleashing a wave of sector growth despite ongoing implementation of regulations. Stablecoins are cryptocurrencies pegged to more stable assets such as the U.S. dollar, distinguishing them from volatile alternatives like bitcoin.

Circle already operates USDC, one of the world’s largest stablecoin networks, but Arc targets emerging applications including agentic commerce where automated bots handle shopping and payments on behalf of consumers. The project is described by Circle as an enterprise-grade blockchain intended to become the economic operating system for the internet. Other participants in the initiative include Global Payments and MoneyGram.

This latest move follows a separate venture announced in June involving Visa, Mastercard, Stripe, Coinbase, BlackRock and others creating Open USD. That stablecoin was billed as open, low-cost and high-throughput, governed by a board of partner companies. The competitive threat posed to Circle’s stock at the time highlighted how card networks are positioning themselves above or between competing stablecoin networks.

Dan Dolev, an analyst from Mizuho Securities who follows Visa closely, described the San Francisco-based company as the ‘stablecoin of stablecoins’ in a report last October. He noted that Visa could be among the biggest winners due to its cross-border network capabilities and central position within the proliferating number of digital assets. The recent announcement involving Circle further suggests that these card networks are becoming integral parts of the broader stablecoin community, reinforcing their goal of serving as essential infrastructure players for blockchain-based payments.
