Points of Focus

• Visa is no longer just experimenting with crypto payments; it is now operating a validator on Tempo.
• With over $33 trillion in annual volume and rapid growth in real-world usage, stablecoins are increasingly competing with traditional networks
• Backed by Stripe and supported by firms like Chainalysis, Tempo is designed as a high-throughput, stablecoin-first network.

Visa has taken a deeper step into blockchain infrastructure, launching a validator node on the Tempo network alongside Stripe and Zodia Custody, as traditional finance firms position themselves closer to the core of stablecoin-based payments.

The move places Visa directly in the transaction validation layer of Tempo, a newly launched layer-1 blockchain designed specifically for high-volume stablecoin settlement.

Rather than building applications on top of blockchain rails, Visa is now participating in securing and operating them, a shift that reflects how large financial institutions are adapting to the rapid growth of on-chain payments.

Stablecoins begin to rival traditional payment rails

The timing of Visa’s validator launch coincides with a surge in stablecoin usage. Total stablecoin transaction volume exceeded $33 trillion in 2025, surpassing Visa’s own annual payment volume of roughly $16–17 trillion.

More importantly, data from Chainalysis shows that stablecoins processed about $28 trillion in ‘real economic’ volume in 2025, growing at a 133% annual rate since 2023.

That growth trajectory has led analysts to project that stablecoin payment volumes could begin matching traditional card networks like Visa and Mastercard sometime between 2031 and 2039.

Despite the scale of on-chain activity, Visa’s direct exposure remains relatively small. The company processes about $4.5 billion annually in stablecoin settlements, a fraction of its total payment volume, but one that is growing steadily.

Tempo built as a ‘stablecoin-first’ network

Tempo is part of a new class of blockchains designed specifically for payments rather than general-purpose smart contracts. Incubated by Stripe and backed by crypto investors, the network removes the need for a native gas token, allowing transaction fees to be paid directly in stablecoins.

This design reflects a broader shift toward what industry participants call ‘stablecoin-native infrastructure,’ where digital dollars act as both the medium of exchange and the operational layer of the network. Tempo also introduces features such as embedded payment metadata and compliance tooling, targeting enterprise and institutional use cases from the outset.

Chainalysis, which added support for Tempo shortly after its launch, described the network as ‘purpose-built for stablecoin payments at scale,’ reinforcing its positioning as infrastructure rather than a speculative trading venue.

Stablecoins drive institutional convergence and regulatory tension 

Visa’s entry into validation comes as financial institutions increasingly move deeper into blockchain infrastructure. The involvement of Stripe and Zodia Custody highlights how multiple layers of the financial system, payments, custody, and compliance, are converging on shared on-chain networks.

This shift is driven by both competitive pressure and structural change. Stablecoins offer near-instant settlement, 24/7 availability, and lower transaction costs compared with legacy payment systems, reducing reliance on intermediaries and batch processing.

For incumbent payment firms, that creates both a threat and an opportunity. Chainalysis analysts warn that institutions that fail to integrate stablecoin rails risk disintermediation as digital payments infrastructure evolves.

However, global policymakers remain cautious about the pace of this transition. The International Monetary Fund has warned that widespread stablecoin adoption could introduce risks to monetary sovereignty, particularly in emerging markets where dollar-backed tokens may displace local currencies.

Similarly, the European Central Bank has raised concerns about financial stability, noting that large-scale stablecoin usage could amplify liquidity stress during periods of market volatility and create new forms of systemic risk if reserves are not sufficiently robust.

These counterarguments highlight a growing tension: while institutions are moving deeper into blockchain infrastructure to capture efficiency gains, regulators are increasingly focused on ensuring that this shift does not undermine financial stability or monetary control.

A long-term bet on payment infrastructure

Visa’s validator move suggests a longer-term strategic shift. While stablecoin usage is still early in consumer payments, institutional adoption is accelerating, supported by regulatory clarity and growing demand for real-time settlement.

The broader market is also expanding rapidly. Stablecoin supply has crossed $300 billion in early 2026, up sharply from previous years, while payment use cases continue to grow across remittances, B2B transactions, and treasury operations.

In that context, operating a validator node is less about current transaction volume and more about positioning. As stablecoin networks evolve into core financial infrastructure, control over validation and settlement layers may become as strategically important as merchant networks are today.

Visa’s move onto Tempo signals that the next phase of competition in payments may not be at the application layer, but in the underlying systems that move money itself.
