Summary
Circle's Q2 earnings showed adjusted EPS beating expectations while revenue missed forecasts, leading to a 3% premarket decline. Despite USDC onchain transaction volume surging 151% year-over-year, revenue grew only 7%, highlighting challenges in the stablecoin business model. Concurrently, in-depth research into five major stablecoin neobanks revealed the fiat rail infrastructure behind compliant on- and off-ramps.
Circle Earnings Present Mixed Picture: Profit Beats but Revenue Growth Lags
Circle's second-quarter earnings report painted a mixed picture for investors. The company posted adjusted earnings of 18 cents per share, surpassing analysts' consensus estimate of 16 cents, while revenue and reserve income rose 7% year-over-year to $701 million, falling short of Wall Street's $712 million expectation. Net income from continuing operations reached $48 million, topping the $43 million estimate, and adjusted EBITDA climbed 8% to $143 million.
Circle shares experienced dramatic volatility in premarket trading following the earnings release, initially jumping 10% before reversing course to fall 3%. This price action reflected market concerns about slowing revenue growth overshadowing the company's profitability achievements.
The Disconnect Between Transaction Volume Surge and Revenue Growth
The most noteworthy phenomenon in Circle's earnings report is the significant disconnect between transaction volume and revenue growth. USDC circulation reached $73.3 billion at the end of June, up 19% year-over-year, while onchain transaction volume surged 151% to $14.8 trillion, demonstrating substantial growth in institutional adoption. However, revenue grew only 7%, far below the rate of transaction volume expansion.
This disconnect reveals a core challenge facing the stablecoin business model: transaction volume growth does not necessarily translate into proportional revenue growth. Stablecoin issuers' primary revenue source is interest income generated from reserve assets, not transaction fees. In an environment of changing interest rates and intensifying competition, even dramatic transaction volume growth may not drive commensurate revenue increases.
The implications extend beyond Circle. As stablecoin adoption accelerates and competition intensifies, issuers must explore new revenue streams while managing the fundamental economics of their business models. The disconnect between usage metrics and financial performance suggests that scale alone may not guarantee profitability in the stablecoin sector.
Unveiling Stablecoin Banking Infrastructure
In contrast to Circle's earnings report, in-depth research into stablecoin neobanks has revealed the infrastructure landscape underpinning this sector. The research covered five major stablecoin neobanks—RedotPay, EtherFi, KAST, Avici, and Gnosis Pay—focusing on how they achieve compliant fiat on- and off-ramps through traditional banking systems.
The research found that the vast majority of stablecoin neobanks do not build their own banking infrastructure. Instead, they rely on a handful of providers to open accounts, process bank transfers, and execute foreign exchange conversions. These underlying providers include OpenPayd, Bridge, Due, and others, which furnish stablecoin neobanks with U.S. account numbers, IBANs, or other personalized banking account information.
From the user's perspective, the fiat account experiences offered by different stablecoin neobanks may appear similar, but the underlying implementation logic differs completely. Everything from supported currencies and FX spreads to KYC verification rules is determined behind the scenes by these underlying providers, and these differences materially impact user costs and experiences.
Testing Data Reveals Dramatic Cost Variations
The research team conducted practical tests comparing EUR payment rails, depositing and withdrawing 5,000 EUR from each neobank. Test results showed that the total cost of a complete deposit-and-withdrawal cycle, including FX spreads and various fees, varied dramatically—from as low as $2 to as high as $130.
RedotPay relies on OpenPayd to provide EUR and GBP virtual accounts (USD not supported), but opening any currency virtual account requires a $7 fee, while other tested platforms offered free account opening. More notably, RedotPay's effective fee for converting EUR to USDC reached $113.69 (2%), the highest level in the testing. A 5,000 EUR test deposit took approximately 60 hours to become available due to additional manual review, while withdrawals were processed by another service provider, Red Dot Payment, in under one minute.
EtherFi's banking rails proved more comprehensive, offering USD, EUR, BRL, MXN, COP, GBP, and AED virtual accounts through two service providers, Bridge and Due, plus support for withdrawals in five additional currencies. Testing showed that depositing 5,000 EUR through Due's virtual account and choosing to receive USDC resulted in 5,695.12 USDC, representing an effective fee of $9.21 (0.16%). Withdrawing 5,000 EUR using USDC balance deducted the equivalent of 5,714.04 USDC, with a fee of $9.34 (0.16%), demonstrating significantly better cost control than RedotPay.
The Strategic Importance of Local Payout Capabilities
The research also found that leading stablecoin neobanks generally possess robust local payout capabilities, enabling withdrawals using local clearing networks in the corresponding currencies. RedotPay's local payout functionality covers an extensive range, spanning over 30 currencies across Latin America, Asia, and Africa, with fees typically amounting to a few dollars depending on the currency, though USD payouts carry the highest fee at $50.50.
This capability is particularly important for global users, as local clearing networks are typically faster and cheaper than international wire transfers. However, the implementation of local payout functionality likewise depends on the capabilities of underlying providers, and different providers exhibit significant variations in regional coverage and cost structures.
The Economics of Compliant Banking Infrastructure
The stablecoin neobank fiat rail infrastructure research reveals a critical reality: compliant fiat on- and off-ramp capabilities represent an essential component of the stablecoin ecosystem, yet most participants choose to rely on specialized providers rather than building in-house. This choice reflects the substantial challenges of obtaining banking licenses, managing compliance costs, and achieving multi-currency coverage.
For stablecoin issuers and custody service providers, understanding the operational logic of these underlying infrastructures is crucial. Differences among providers in FX costs, transfer speeds, currency coverage, and KYC procedures directly impact end-user experience and business scalability. Selecting appropriate underlying providers, or considering in-house development of certain infrastructure components when necessary, represents an important strategic decision in stablecoin business planning.
The research methodology employed—actually moving tens of thousands of euros through these systems and documenting real costs and timing—provides valuable empirical data for industry participants evaluating infrastructure partners or building competitive offerings.
Regulatory Considerations in Fiat-Crypto Bridges
The reliance on traditional banking infrastructure highlights the regulatory complexities inherent in bridging fiat and crypto ecosystems. Each underlying provider must navigate banking regulations, anti-money laundering requirements, and cross-border payment rules across multiple jurisdictions. The KYC procedures, account opening requirements, and transaction monitoring protocols implemented by these providers reflect their interpretation of and compliance with applicable regulations.
For users, this means that the regulatory framework governing their stablecoin neobank experience is largely determined by the underlying provider, not the consumer-facing platform. Understanding these relationships becomes important for assessing risk, anticipating potential service limitations, and evaluating the long-term viability of different platforms.
The variance in account opening fees, processing times, and manual review requirements observed in the testing reflects different providers' risk management approaches and regulatory compliance strategies. These differences may become more pronounced as regulatory frameworks evolve and enforcement intensifies.
Future Challenges for the Stablecoin Business Model
Circle's earnings report and the stablecoin banking infrastructure research together illuminate two major challenges facing the stablecoin sector: first, how to achieve revenue growth commensurate with transaction volume expansion; second, how to efficiently and cost-effectively connect traditional financial systems with blockchain ecosystems within compliant frameworks.
As stablecoin adoption rates increase and competition intensifies, issuers will need to explore new revenue sources, potentially including value-added services, institutional-grade solutions, and cross-border payment optimization. Simultaneously, the maturity and cost structure of fiat rail infrastructure will directly impact stablecoin usability and adoption velocity.
From an industry development perspective, the healthy evolution of the stablecoin ecosystem requires finding balance among innovation and compliance, efficiency and cost, decentralization and traditional finance integration. Circle's earnings performance and the current state of stablecoin neobank infrastructure provide important empirical data and analytical frameworks for understanding this balance.
The path forward likely involves continued specialization, with some players focusing on stablecoin issuance and reserve management while others concentrate on building efficient, compliant fiat rails. The companies that successfully navigate both dimensions—or forge effective partnerships bridging them—will be best positioned to capture value as stablecoins move toward mainstream adoption.
For institutional participants evaluating stablecoin infrastructure, the research underscores the importance of due diligence not just on consumer-facing platforms but on the underlying banking and payment providers that ultimately determine cost structures, processing times, and operational reliability. As the sector matures, transparency around these relationships and their implications will become increasingly important for users and institutional clients alike.
