Circle vs Ripple: how AI, stablecoins, and agents could decide the winner

Stablecoins are quietly becoming the core infrastructure of the digital economy. Behind the headlines about price action, there’s a much bigger story playing out: which networks will actually power payments, on-chain finance, and the coming wave of AI-driven “agent” apps.

Two of the biggest contenders are Circle (USDC) and Ripple (XRP and the XRP Ledger). Both are deeply connected to banks, institutions, and payment rails—but they’re taking very different paths into the future of money.

The new risk: AI, bots, and protocol vulnerabilities

As crypto infrastructure matures, a new risk vector is emerging: AI and automated bots discovering and exploiting protocol flaws at scale. We’ve already seen AI tools uncover vulnerabilities that humans missed, and that risk grows as more value moves on-chain.

A recent example involved the XRP Ledger. During an "attackathon" event, a vulnerability was discovered that could theoretically allow anyone to mint infinite XRP tokens. The bug was reported in September, confirmed about a month later, and publicly disclosed around 30 days after that.

While the issue was handled and never turned into an actual exploit, the timeline highlights a problem: when a network is tied to a major company, public markets, and institutional flows, a month-long window between discovery and disclosure can be a serious concern. As more attackers use AI, response times and security processes will matter as much as technology itself.

Ripple’s growing exposure: XRP, Evernode, and RLUSD

Ripple and the XRP Ledger are entering a new phase of visibility and risk. One major catalyst is Evernode, which is now trading on Nasdaq and is directly connected to the XRP ecosystem. This means a very public, regulated company is now tied to XRP’s performance and reliability.

At the same time, stablecoin activity is ramping up around Ripple. Jack McDonald and his team are rolling out RLUSD, a stablecoin issued on the XRP Ledger with links to Standard Chartered’s custody services and the LMAX Group. This ties XRP more closely to traditional finance (TradFi) while also increasing its attack surface and investor scrutiny.

The upside: more institutional access and legitimacy. The downside: if the underlying ledger looks underused or insecure, the whole stack—from token to corporate equity—can come under pressure.

Is there really “nothing happening” on the XRP Ledger?

Inside the XRP community, there’s a clear pushback against the idea that the XRP Ledger is quiet. Names like First Ledger, Doppler Finance, Flare, Braza Bank, Aviva Investors, and DBS are frequently cited, especially in the context of real-world assets (RWAs).

However, when you zoom out to on-chain data, a different picture appears. Total value locked (TVL) and activity on the XRP Ledger have largely flatlined compared to the broader stablecoin and DeFi markets. In RWA rankings, XRP Ledger currently sits much lower than leaders like Ethereum and Solana, and even trails networks such as Stellar.

This doesn’t mean nothing is being built—but it does suggest that usage, liquidity, and yield opportunities are not yet competitive with the top chains.

Why yield is pulling stablecoin liquidity away from XRP

Stablecoin users are increasingly chain-agnostic. They’ll move to whichever network offers the best mix of safety, liquidity, and—crucially—yield.

We’ve seen this clearly with products like Robinhood’s USDG, which attracted attention with yields around 7%. When a platform offers competitive, transparent rewards on a stable asset, users will bridge across chains to chase that yield.

Something similar is happening with RLUSD. At one point, XRP-based RLUSD briefly overtook Ethereum in a narrow metric, but shortly after, RLUSD usage on Ethereum surged. The takeaway: if a stablecoin can earn better, more accessible yields on Ethereum, that’s where the liquidity will go—regardless of where the issuer’s brand is strongest.

Circle’s strategy: from TradFi rails to the “new economy”

Ripple and Circle are both deeply integrated with traditional finance. Ripple has long focused on cross-border payments and bank rails. Circle also works with banks and payment giants—but its strategy is more aggressively tilted toward the on-chain economy.

USDC is already the leading regulated stablecoin used across DeFi, exchanges, and on-chain payments. Circle is now pushing into a new phase: building infrastructure for AI-driven agents and on-chain applications that can manage money, execute workflows, and interact with multiple protocols autonomously.

In other words, Ripple is still largely optimizing the old rails. Circle is building for the next rails—where software agents, not just humans, will be the main users of financial infrastructure.

Agentic finance: why AI agents matter for stablecoins

“Agentic commerce” is a term you’ll hear more often. It refers to AI agents that can act on your behalf—paying bills, optimizing yields, managing subscriptions, even handling aspects of tax and cash management.

Circle is positioning USDC as the default money for these agents. Imagine thousands of small AI apps that:

• Scan DeFi for the best stablecoin yields and rebalance your capital automatically
• Handle recurring payments and cross-border transfers 24/7
• Integrate with your business systems to manage invoices and payroll
• Interact with RWA platforms to move between tokenized treasuries, funds, or credit products

For this world, you need a stable, programmable, globally usable asset that settles in seconds, runs 24/7, and plugs into the largest DeFi and RWA ecosystems. That’s exactly the niche USDC is occupying today—especially on Ethereum and Solana.

USDC’s dominance by the numbers

On-chain data backs up USDC’s lead. Visa’s own analytics show that in lending protocols—one of the most important categories for real usage—USDC absolutely dwarfs competitors. Its transaction volume and integration footprint make other stablecoins look almost negligible by comparison.

Even when new stablecoins launch with big brand names or consortiums behind them, they often have to pay heavy subsidies just to attract users. Many of these efforts become money-losing products that fail to reach meaningful scale. Meanwhile, USDC continues to grow organically across chains and platforms.

Circle vs XRP: market cap and performance potential

When you compare Circle (as an equity and ecosystem) against XRP (as a token), the performance gap is already significant. On a token vs stock basis, Circle has outperformed XRP by multiples. If you compare Circle’s current trajectory to XRP’s all-time high, the difference becomes even starker, especially if Circle sustains its growth in USDC adoption, RWAs, and agentic infrastructure.

There’s also a structural difference: Ripple’s valuation is still heavily tied to its XRP holdings. Circle, as a public company, has the potential to launch a token later—layering a new asset on top of an already dominant stablecoin business, rather than having its equity value anchored to a pre-existing token.

Ripple’s transparency problem: sunsetting the XRP markets report

For years, Ripple published a quarterly XRP markets report. These reports gave investors and users insight into XRP sales, holdings, and how the company was using its reserves. They also gave regulators ammunition, most notably during the SEC’s campaign against Ripple.

In its Q1 2025 update, Ripple announced it would sunset the report in its current form starting Q2 2025. From a regulatory-risk perspective, this may feel safer. But from a market-trust perspective, it’s a concern.

When a company holds a large portion of a token’s supply and actively sells into the market, transparency is critical. Without clear reporting, it becomes harder for holders to understand dilution, treasury strategy, and how closely Ripple’s fundraising is tied to XRP price pressure.

This matters even more as Ripple continues to raise capital at valuations the market doesn’t always agree with—especially when XRP’s price has dipped after some funding rounds, signaling that investors don’t fully buy the implied value.

FedNow vs USDC: why central bank rails may not be the threat people think

Some investors have sold out of Circle exposure because they believe FedNow, the Federal Reserve’s instant payment system, will make stablecoins obsolete. On paper, FedNow offers fast domestic transfers between US banks—so why would you need USDC?

The comparison breaks down when you look at the details:

• Scope: FedNow is US-only; USDC is global.
• Availability: FedNow runs through banks and their hours/controls; USDC is 24/7 on public chains.
• Cost: On-chain USDC transfers can be extremely cheap, especially on networks like Solana.
• Finality: USDC on fast chains can settle in hundreds of milliseconds with immediate finality.
• Access: All you need is a wallet; no bank account required.

FedNow may improve legacy banking, but it doesn’t replace a programmable, borderless, composable stablecoin that can plug into DeFi, RWAs, and AI agents. In that sense, it’s not a USDC killer—it’s just another rail that can coexist with, or even complement, on-chain money.

Solana, USDC, and ultra-fast settlement

Solana is emerging as a key piece of USDC’s growth story. The network has pushed block finality down to the hundreds of milliseconds—around 218 ms on a recent full epoch, with targets closer to 150 ms. That’s dramatically faster than earlier benchmarks and far ahead of many older chains.

For stablecoins, this speed matters. It enables:

• Near-instant merchant payments
• High-frequency trading and market-making
• Real-time settlement for agentic finance apps
• A smoother user experience that feels like Web2, not legacy crypto

With USDC as the primary stablecoin on Solana, the two form a powerful combo: a fast, low-cost execution layer plus a trusted, regulated dollar asset.

Where does this leave XRP and Ripple?

Ripple still has major strengths: regulatory clarity in some jurisdictions, deep relationships with banks and payment providers, and a strong brand in cross-border settlements. There’s also a large, committed community and ongoing efforts in RWAs and institutional products.

However, the data suggests XRP is not yet winning where the next wave of growth is likely to come from: DeFi lending, on-chain yields, AI agents, and composable stablecoin use across multiple chains. Unless the XRP Ledger can attract more developers, more liquidity, and more competitive yield opportunities, it risks being overshadowed by ecosystems where USDC and other assets are already thriving.

The bottom line: Circle vs Ripple in the next cycle

Circle and Ripple are both betting on a future where digital dollars and tokenized assets move freely across the globe. But their strategies diverge sharply:

• Ripple is still heavily tied to XRP, bank rails, and enterprise partnerships—and is reducing public transparency around its token economics.
• Circle is doubling down on USDC as the default stablecoin for DeFi, RWAs, and AI agents, with strong backing from major validators and institutions like BlackRock, DTCC, Galaxy Digital, Standard Chartered, and Visa.

As AI agents, yield competition, and real on-chain usage become the main drivers of value, the networks that offer the best combination of speed, safety, liquidity, and programmability are likely to win. Right now, that points toward the USDC ecosystem—especially on Ethereum and Solana—unless XRP can rapidly close the gap in activity, incentives, and developer traction.
