There's a number worth pausing on: stablecoin transaction volume hit $33 trillion in 2025. That figure, cited by Ripple in a recent payments infrastructure analysis, puts stablecoins ahead of global credit card volume for the year. Visa and Mastercard built decades of trust, merchant relationships, and regulatory goodwill to reach their current scale. Stablecoins matched that throughput faster than almost anyone predicted.

But if you're expecting the next chapter of this story to be about one dominant stablecoin taking over the global payments stack — the "crypto Visa" narrative — the reality on the ground is considerably more complicated, and considerably more interesting.

Nobody Is Betting on a Single Asset

According to Ripple's analysis, the institutions moving the most stablecoin volume aren't consolidating around one asset. They're running simultaneously across USDT, USDC, RLUSD, EURC, and a growing list of local-currency stablecoins — switching between them depending on the payment corridor, counterparty requirements, and local regulatory environment.

That's not a transition phase. That's the architecture.

A cross-border payment from a US business to a supplier in Southeast Asia might clear in USDC because the counterparty's exchange supports it. A treasury operation in the UAE might use RLUSD because it fits the jurisdiction's licensing framework. A European bank with its own digital asset platform might settle in EURC to stay within the EU's MiCA compliance perimeter.

Each corridor has its own optimal path. The practical implication: any payment infrastructure company, fintech, or business treasury that built around a single stablecoin assumption is going to need to retrofit. The winners in the next phase of stablecoin payments infrastructure won't be the ones with the best single token. They'll be the ones with the best multi-asset routing.

What This Means for US-Based Businesses

For US companies, particularly those with international operations or supplier networks, this multi-stablecoin reality creates both opportunity and operational burden.

The opportunity: on-chain dollar liquidity is now genuinely functional at scale. Sending $500,000 from a US business account to an overseas supplier via stablecoin rail is no longer a proof-of-concept exercise — it's an option on the table with real settlement times, real cost advantages over SWIFT, and growing regulatory clarity (especially post-GENIUS Act framework discussions).

The burden: treasury teams now need to think about stablecoin diversification the same way they think about FX exposure. Which assets does your counterparty accept? What's your issuer risk profile across USDT versus USDC? Do you have custody infrastructure that handles multiple token standards? These questions aren't hypothetical for large enterprises anymore — they're operational.

For small and mid-size US businesses, the decision tree is simpler but the stakes are similar. If you're using stablecoin payments for any international work, defaulting to USDC on Ethereum or Solana covers most counterparty scenarios today. But staying locked into one setup without monitoring what your partners actually settle in is how you end up with friction you didn't expect.

Institutional Infrastructure Is Getting Serious

The custody side of this equation is worth particular attention. Ripple has been positioning its custody offering as core infrastructure for institutions entering digital asset operations, and the broader trend supports the emphasis. From European regulated banking platforms to UAE tokenized real estate, institutions are moving from pilot programs into production use — and they need somewhere to hold these assets securely.

Custody is the unglamorous half of payments infrastructure. It doesn't generate headlines, but no institution will route serious volume through a stablecoin rail they don't have a credible custody answer for. The emergence of institutional-grade custody options — whether from Ripple, Anchorage, BitGo, or bank-affiliated platforms — is what's actually making the $33 trillion number possible to sustain and grow.

For US institutions watching from the sidelines: the infrastructure to participate in on-chain dollar payments is no longer experimental. The question is whether your compliance, legal, and treasury teams have caught up with the technical feasibility.

The Fragmentation Problem Won't Self-Resolve

Here's the tension at the center of this market: stablecoins work best when there's deep, consolidated liquidity. But regulatory requirements, counterparty preferences, and issuer competition are pulling in the opposite direction — toward fragmentation.

This is exactly the problem that aggregators like Snag Solutions' newly launched agg.market are trying to solve on the prediction market side — routing across fragmented liquidity venues to give users the best price. The same logic will increasingly apply to stablecoin payments rails. As the number of active stablecoins grows, the value of smart routing infrastructure — systems that automatically find the cheapest, fastest, most compliant path for a given payment — scales with it.

Expect to see a layer of stablecoin routing and settlement abstraction emerge between end-users (both consumers and businesses) and the underlying token mechanics. Much like how most people using Stripe don't think about which card network their transaction cleared on, the goal of mature stablecoin payments infrastructure is to make the asset selection invisible to the end user while optimizing it behind the scenes.

That layer doesn't fully exist yet for stablecoins. Building it is the actual infrastructure prize of this decade.

Fraud Risk Is Real — and Regulators Are Watching

It would be incomplete to discuss stablecoin and payments infrastructure growth without noting what's happening on the consumer protection side. Canada's proposed nationwide ban on crypto ATMs — flagged as a "primary method" for scammers and money laundering by Canadian regulators — is a reminder that broader crypto payment access remains a double-edged issue.

Crypto ATMs represent a much more retail-facing, less regulated entry point into digital assets than institutional stablecoin rails. The regulatory response in Canada, while geographically contained, reflects a pattern that US regulators are watching closely: where crypto payment access is loosely regulated and identity verification is minimal, fraud follows. Hong Kong's warning about fake tokens impersonating an HSBC stablecoin that doesn't even exist yet underscores how quickly bad actors exploit payment infrastructure gaps.

For US consumers and small businesses, this is a practical reminder: the on-chain dollar rails that work are the ones with proper issuer transparency, regulated custody, and verifiable counterparty identity. That's not bureaucratic overhead — that's what separates infrastructure that scales from infrastructure that gets banned.

The Grounded Takeaway

Stablecoins clearing more volume than global credit cards in a single year is a genuine milestone, not a press release talking point. But the infrastructure story is still being written, and the shape of it is messier than the headline suggests.

Multi-asset fragmentation, custody requirements, routing complexity, and fraud exposure are the real operating environment. US businesses with cross-border payment needs should be taking stablecoin rails seriously — not because crypto won, but because the cost and speed advantages are real and competitors who adopt first will have operational leverage. Just don't bet on a single-asset, set-it-and-forget-it approach. The institutions already in the space aren't.
