The Rise of Stablecoin Infrastructure: Rain’s Strategic Position in a Regulated Era

The global financial system is undergoing a quiet revolution. Stablecoins—digital assets pegged to fiat currencies—are no longer niche experiments but foundational tools for cross-border commerce, institutional treasury operations, and consumer payments. At the heart of this transformation lies Rain, a stablecoin infrastructure platform that has raised $58 million in Series B funding, led by Sapphire Ventures and supported by Galaxy Ventures, Samsung Next, and others [1]. This investment, bringing Rain’s total funding to $88.5 million, underscores its role as a critical enabler of the stablecoin ecosystem, particularly in the wake of regulatory clarity provided by the U.S. GENIUS Act and the EU’s MiCA framework.

Regulatory Clarity as a Catalyst

The GENIUS Act, enacted in July 2025, has redefined the legal landscape for stablecoins in the United States. By classifying payment stablecoins as neither securities nor commodities and placing oversight under banking regulators, the act has removed a major barrier to institutional adoption [2]. Similarly, the EU’s MiCA regulation has established a unified framework for crypto assets, mandating transparency, reserve backing, and compliance standards [3]. These developments have normalized stablecoins as safe, liquid assets, enabling institutions to integrate them into core financial systems.

Rain’s infrastructure is uniquely positioned to benefit from this regulatory shift. Its platform supports the entire stablecoin lifecycle—deposits, storage, spending, and withdrawals—via a single API, while adhering to enterprise-grade compliance standards such as PCI DSS and SOC 2 [4]. The company’s 10x growth in transaction volume since January 2025, now spanning 1.5 billion users across 150+ countries, reflects the surge in demand for compliant, scalable solutions [5].

Institutional Adoption and Technical Differentiation

Rain’s strategic partnerships further solidify its market position. As a Visa Principal Member, the company processes 100% of its card payment volume in stablecoins on Visa’s network, enabling users to spend digital assets at any Visa-accepted location [6]. This technical differentiation—embedding stablecoins directly into traditional payment rails—addresses the “last-mile” problem that has long hindered adoption. Additionally, Rain’s expansion to support Solana, Tron, and Stellar blockchains allows enterprises to leverage multiple ecosystems for cross-border transactions [7].

Institutional demand for stablecoin infrastructure has also been amplified by the GENIUS Act’s dual-track licensing model, which permits both federal and state-qualified issuers. This flexibility aligns with Rain’s global expansion strategy, as it scales operations in Europe, the Middle East, Africa, and Asia-Pacific [8]. Key investors like Sapphire Ventures and Samsung Next recognize Rain’s potential to redefine payments by connecting stablecoins to Visa’s global network, a move that democratizes access to digital commerce [9].

The Path Forward

As regulatory frameworks mature, the stablecoin infrastructure market is poised for exponential growth. Rain’s focus on compliance, technical innovation, and institutional partnerships positions it to capture a significant share of this market. The company’s recent funding will accelerate hiring in engineering, commercial, and compliance teams, ensuring it can meet the demands of a rapidly evolving landscape [10].

For investors, Rain represents more than a fintech play—it is a beneficiary of a structural shift in global finance. The convergence of regulatory clarity, institutional adoption, and technological innovation is creating a new paradigm where stablecoins serve as the backbone of modern commerce. Rain’s ability to navigate this transition with speed and precision makes it a compelling case study in the future of financial infrastructure.
