15,000 Transactions a Day: Rosatom Shifts a Key Fintech System to a Fully Russian Platform

Core of the Project: What's Been Done

The Corporate Settlement Center is a centralized platform that automates treasury operations, including payment accounting, cash-flow management, contractor settlements, and integration with banking channels.

Greenatom’s team migrated the system to Russian-made database management and middleware solutions while maintaining a familiar interface, business logic, and workflows for end users. Beneath the surface, however, it now runs entirely on certified domestic technologies. This move eliminated dependence on foreign vendors and simplified the maintenance of critical financial processes across Rosatom’s ecosystem.

Technical Implementation Highlights

The transition relied exclusively on certified Russian products, including database systems, integration platforms, and cryptographic modules. A key achievement was ensuring that the migration required no change in user behavior or payment procedures.

That stability was crucial—financial platforms are notoriously difficult to re-engineer in segments. The Greenatom team’s success lay in maintaining the system’s full operational continuity while completely replacing its technological core.

In replacing the Corporate Settlement Center’s technology stack, our main goal was to preserve the user interface and functionality while ensuring a seamless transition. We achieved that goal, though the project presented significant challenges. At the industry conference, we shared insights into the key issues encountered during implementation and detailed how we reached the target performance benchmarks for the re-engineered system

Scale and Reliability

The system handles more than 15,000 transactions daily and connects to dozens of corporate applications and banking gateways. Its centralized settlement module supports over 300 corporate entities within Rosatom, making it a mission-critical element of the company’s financial infrastructure.

The migration was executed with zero downtime. User operations and banking communications continued uninterrupted, and in some workflows, overall performance even improved. The Corporate Settlement Center project was recognized at the CIPR Digital 2025 industry awards as the “Best Fintech Project.” The accolade confirmed that the import substitution was more than a formal compliance effort—it enhanced business resilience, transparency of financial operations, and reduced operational risks.

Greenatom has also developed several other systems included in Russia’s national software registry, further cementing its reputation as a trusted integrator for certified IT solutions and lifecycle support.

Results and Outlook

The migration process was carried out in close cooperation with users, banking partners, and technical support teams. Greenatom tested migration scenarios in sandbox environments and gradually rerouted transaction flows to the new services. In parallel, the project underwent extensive security audits and component certifications. This phased approach minimized operational risk.

The system is now positioned as a foundation for future innovation. Planned upgrades include expanded analytics modules for cash-gap forecasting, automated risk management, and integration of digital financial assets into Rosatom’s internal funding operations. The successful transition also opens opportunities to export both the technology and the implementation methodology to other state corporations and industries requiring highly resilient financial infrastructure.
