Stablecoin infrastructure debate

Stablecoins are being pitched less as crypto bets and more as payment pipes, with Stripe, Mastercard, Circle and Paxos building tools to move dollars on blockchain networks. (chainalysis.com) A stablecoin is a digital token designed to hold a fixed price, usually $1, so companies can send value online without the price swings of Bitcoin or Ether. Visa said the appeal for cross-border payments and merchant settlement is 24/7 availability, near-instant settlement and software-driven automation. (visa.com) Chainalysis said stablecoins processed $28 trillion in “real economic volume” in 2025 and projected $719 trillion by 2035 under organic growth, with a higher case nearing $1.5 quadrillion. The firm tied that outlook to payment deals including Stripe’s Bridge acquisition and Mastercard’s move on BVNK. (chainalysis.com) (mastercard.com) Those headline numbers come with caveats. Visa said retail-sized transfers made up less than 1% of adjusted stablecoin volume through March 2025, and said much onchain activity still reflects trading, automated programs and other flows that do not map cleanly to everyday consumer payments. (visa.com) That tension shows up in the market data. Coin Metrics put the stablecoin market above $230 billion, while Visa said circulating supply was approaching $250 billion in 2025 with 47 million monthly active users across chains. (coinmetrics.io) (visa.com) Builder activity in the United States is increasingly centered on infrastructure rather than consumer tokens alone. Circle says its platform now includes Circle Payments Network and managed payments tools, while Paxos launched a stablecoin payments platform on October 15, 2024, with Stripe as its first customer. (circle.com) (paxos.com) Stripe has pushed the category deeper into mainstream payments. It completed its Bridge acquisition in early 2025 and later said Stablecoin Financial Accounts would be available to businesses in 101 countries through its money-management products. (stripe.com 1) (stripe.com 2) Mastercard made the same bet from the card-network side. On March 17, 2026, it said it would acquire stablecoin infrastructure firm BVNK for up to $1.8 billion to connect on-chain payments with fiat rails. (mastercard.com) The policy backdrop also shifted in Washington. Congress.gov says the Guiding and Establishing National Innovation for U.S. Stablecoins Act, introduced on May 1, 2025, created a framework for “payment stablecoins,” and the White House and Office of the Comptroller of the Currency said it was enacted on July 18, 2025. (congress.gov) (whitehouse.gov) (occ.gov) Bottom-up payment data still looks much smaller than top-down blockchain totals. A Castle Island Ventures and Artemis sample of 20 stablecoin payments companies attributed $94.2 billion in settled payments from January 2023 through February 2025, with a $72.3 billion annualized run rate as of February 2025, led by business-to-business flows. (castleisland.vc) The debate now is not whether stablecoins exist at scale, but which volumes count as actual payments and how much of the plumbing will move into regulated finance. The answer is starting to come from payment companies, not just crypto traders. (visa.com) (chainalysis.com)
