SDK.finance Expands Modular Core Infrastructure to Accelerate Scalable Fintech Growth

VILNIUS, Lithuania, September 8th, 2026, FinanceWire

SDK.finance, a European provider of core banking and payment software, today announced the expansion of its modular financial infrastructure platform. The enhanced system provides banks, electronic money institutions (EMIs), payment service providers, and emerging fintech enterprises with an API-driven core architecture engineered to streamline multi-product scalability. The platform equips financial institutions with a unified foundation for managing transaction processing, accounting ledgers, and external integrations, enabling them to expand operations without generating proportional increases in operating expenses or systemic risk.

The deployment aligns with a significant structural transition across the global financial technology sector. According to a McKinsey analysis, fintech companies generated approximately $650 billion in global revenue in 2025, representing an annual growth rate of roughly 21 percent. However, market dynamics have shifted away from growth at any cost toward a disciplined equilibrium requiring verified operational profitability, regulatory maturity, and technical resilience. While institutions historically competed on front-end metrics such as customer acquisition and top-line payment volumes, market sustainability increasingly depends on the operational efficiency hidden beneath consumer interfaces, within the institution's core transactional and ledger infrastructure.

Core infrastructure directly governs the fundamental unit economics of modern financial businesses. In many growing institutions, customer applications conceal a fragmented assembly of legacy databases, third-party payment gateways, and ad-hoc reconciliation protocols. When platforms expand into new regions or introduce novel financial products, this fragmentation generates compounding operational friction. Engineering teams must build custom code for every new account type, reporting workflows become manual, and compliance auditing costs escalate. SDK.finance addresses these structural barriers by establishing a reusable operational foundation. By standardizing how balances, limits, fees, and currency rules are processed across all workflows, the platform provides scalable operating leverage across an enterprise’s entire product catalog.

To optimize the relationship between transaction growth and underlying expenses, the updated infrastructure introduces advanced automated transaction matching and exception handling capabilities. In high-volume financial environments, manual reconciliation teams often expand in parallel with transaction volume, effectively scaling administrative payroll rather than software efficiency. SDK.finance resolves this bottleneck through real-time ledger accounting and automated discrepancy detection. Operational issues and reporting adjustments are resolved through transparent, auditable reversal records rather than destructive database edits, ensuring that institutions maintain comprehensive audit trails for regulatory authorities while reducing operational overhead.

The modular framework also resolves the technical complexities associated with international expansion across varied currencies and regulatory regimes. Expanding into foreign markets traditionally requires institutions to duplicate compliance logic and rebuild regional payment stacks from scratch. Research from the Bank for International Settlements emphasizes that financial market infrastructures must remain secure, resilient, and adaptable as transaction volumes and technological landscapes evolve, noting that modular settlement architecture provides essential operational agility. SDK.finance allows institutions to reuse core financial components across borders, dynamically configuring settlement rules, foreign-exchange flows, and local compliance checks without disrupting primary customer journeys.

"The real test of fintech infrastructure is not whether it can support a successful launch, but whether it can support the next ten products, markets, and integrations without multiplying operational costs and complexity," said Alex Malyshev, Chief Executive Officer of SDK.finance. "Customer growth attracts investor attention, but the infrastructure behind that growth determines whether the business can scale profitably over the long term."

The platform provides access to more than 650 REST APIs, allowing financial institutions to modernize their infrastructure progressively without executing disruptive, high-risk migrations. Technical teams can integrate SDK.finance alongside existing core banking systems or transaction platforms, connecting digital wallets, remittance rails, and compliance tools through a single operational layer. This architectural flexibility enables established institutions to reduce technical debt while accelerating time-to-market for future financial innovations.
