Visa Expands Stablecoin Pilot to Polygon, Base; Settlements Hit $7B

Visa has broadened its stablecoin settlement pilot to incorporate Polygon and four additional blockchain networks, signaling a continued push into crypto-native settlement rails for traditional payments. The program, launched in 2023, allows partners to settle transactions using stablecoins instead of conventional banking rails. The newly added networks are Polygon, Base, the Canton Network, Arc and Tempo, joining existing supported chains such as Ethereum, Solana, Stellar and Avalanche.

Visa says the pilot is aimed at evaluating whether stablecoins can offer faster settlement, round-the-clock availability, and efficiencies in cross-border payments. The company disclosed in a press release that the initiative has reached an annualized settlement run rate of roughly $7 billion, up about 50% quarter over quarter. While that growth is meaningful, Visa notes that the volume remains a smaller portion of its broader payments business.

Key takeaways

• Visa expands its stablecoin settlement pilot to five new networks—Polygon, Base, Canton Network, Arc and Tempo—in addition to Ethereum, Solana, Stellar and Avalanche already supported.
• The pilot’s annualized settlement run rate is approximately $7 billion, representing about 50% quarter-over-quarter growth, according to Visa.
• The expansion underscores a deliberate exploration of faster, 24/7 settlement and efficiency gains in cross-border transactions as part of Visa’s broader stablecoin strategy, including related partnerships.
• Industry momentum is rising, with Mastercard enabling stablecoin-linked card spending in the United States and fintechs accelerating blockchain-based settlement workflows, such as Modern Treasury’s Polygon integration.
• Regulatory clarity around stablecoins is evolving in parallel, with legislation like the GENIUS Act shaping the environment for payment stablecoins and on-chain settlement.

Expanding the pilot and what changes

The expansion broadens the scope of Visa’s attempt to validate stablecoin settlement as a practical bridge for traditional finance to move faster and operate more continuously. By adding Polygon, Base, the Canton Network, Arc and Tempo to the existing lineup, Visa is testing a wider array of Layer 2s and cross-chain options that could influence how institutions approach on-chain liquidity and interbank settlement rails. Visa characterizes the pilot as a structured exploration rather than a mass rollout, aiming to quantify potential improvements in settlement speed, reliability, and cost.

As part of its ongoing push into blockchain-based infrastructure, Visa highlighted the broader strategic value of stablecoin settlement. The firm’s comments frame stablecoins as a potential enabler of around-the-clock settlement and cross-border efficiency, which could translate into material benefits for partners that operate at a global scale. The latest numbers—roughly $7 billion in annualized settlement—illustrate tangible progress, even as the pilot remains a small slice of Visa’s total payments landscape.

In March, Visa expanded its collaboration with Bridge, a Stripe subsidiary, to support a global card program that enables stablecoin-linked payments. The development signals a broader appetite for bridging stablecoins and traditional consumer-facing payment experiences, where on-chain settlement could reduce friction for merchants and users alike. That move complements the ongoing pilot by linking stablecoin settlement to card-based spend, a critical channel for mainstream adoption.

Industry momentum and regulatory environment

The steady growth of stablecoin settlement efforts reflects a broader industry pattern as major payments firms experiment with on-chain settlement layers. Mastercard has been active in this space as well, enabling stablecoin-linked card spending in the United States through wallet integrations, marking a parallel track in the push to normalize crypto-based settlement within everyday commerce.

Beyond card programs, fintechs are integrating blockchain-enabled settlement into their workflow. Modern Treasury, a payments software provider, announced its integration with Polygon to help businesses move stablecoin payments more quickly, a move that adds to the ecosystem’s momentum toward on-chain settlement. The U.S. regulatory landscape is also shifting gradually; the GENIUS Act provides clearer standards for payment stablecoins, a development shaping both policy and market participants’ risk and compliance planning. The balance of evolving regulation with rapid fintech innovation will influence how much-scale adoption of stablecoin settlement ultimately achieves.

On the broader market front, stablecoins continue to grow. DeFiLlama data indicates that the total value of stablecoins in circulation has surpassed $320 billion, up roughly 150% since early 2024. That expansion underscores both the demand for stable value on-chain and the potential liquidity that could underpin new settlement rails as financial institutions test and deploy cross-chain flows.

What to watch next

Investors and builders should monitor whether the expanded network support translates into measurable improvements in settlement speed, cost, and reliability for partner programs, as well as how institutional participants respond to the evolving regulatory backdrop. The coming quarters will reveal whether Visa’s pilot can scale beyond pilots and become a meaningful component of the broader payments infrastructure, alongside rising activity from competitors and fintechs pursuing similar goals.

For readers tracking the ecosystem, the ongoing integration work—both in corporate pilots like Visa’s and in third-party workflows such as Modern Treasury’s Polygon collaboration—will indicate where on-chain settlement might become a normalized option in enterprise payments. As policy clarity improves and liquidity expands, the next phase of stablecoin settlement could reveal its true potential for cross-border efficiency and around-the-clock operations.
