Digital Tenge for the Eurasian Bank: How IceRock Development Integrated the National CBDC in 2.5 Months for a Presentation to the Government of the Republic of Kazakhstan

We do not just write code, we also save strategic releases. IceRock Development commits to implementing complex FinTech projects and integrating government initiatives (CBDC, Open Banking) into existing enterprise banking architectures, even under extremely tight deadlines. Our focus is on predictable time-to-market, transparent management, and system resilience that meets the highest government standards.

A New Era of FinTech: Why Banks Need to Adopt CBDC

The global financial system is undergoing a fundamental transformation: central banks are moving toward launching digital currencies (CBDC). In Kazakhstan, this trend has developed certain contours with the launch of the Digital Tenge platform by the National Bank of Kazakhstan.

For second-tier banks (STBs), integration with the National Bank’s platform is not just about following trends; it is a strategic necessity. This includes access to new government initiatives, more transaction transparency, and the opportunity to be the first to offer clients a cutting-edge financial product. However, in practice, such integration presents immense technological challenges. Conservative banking systems (Core Banking) have to be bridged with the latest blockchain platforms or distributed ledgers from the Central Bank, while ensuring absolute security and seamless user experience (UX).

In this article, the IceRock Development team shares a real-world case study of how we helped our partner, Eurasian Bank, become one of the pioneers in implementing the Digital Tenge in Kazakhstan.

Challenge: a project of national significance and an extremely tight deadline

For us, the story of this project began in late August 2023. The constraints were extremely strict:

1. The event: The Congress of Kazakhstan Financiers, featuring the President of the Republic of Kazakhstan Kassym-Jomart Tokayev, was scheduled for November 15, 2023. This is where Eurasian Bank was to publicly demonstrate the working technology.
2. Time frame: Less than 2.5 months for analytics, development, integration, testing, and deployment to production. For the banking enterprise segment, this timeline is virtually impossible.
3. Business task: Implement a specific, socially significant scenario: enabling individuals to receive social benefits from the regional administration in digital tenge.

Our task was not just to build a pretty demo but to implement an end-to-end process that would run like clockwork during the presentation to the country's top leaders.

IceRock Development’s Technical Solution

To meet the deadline without compromising on quality, our team (including dedicated analysts and senior developers) launched two parallel workstreams: upgrading the mobile app and enhancing the backend.

1. Backend & Integration: The bank’s existing architecture had to be handled with care. We could not afford to break what was already working. For this reason, we added:
2. An isolated microservice that we developed for direct and secure interaction with the National Bank’s Digital Tenge platform,
3. Various new services.
4. Eurasian Bank Mobile App (Frontend): For an end user (bank customers receiving social benefits), the process had to appear as familiar as possible. We implemented the following features:
5. New entity type: Support for CBDC (Central Bank Digital Currency) cards within the user’s general wallet.
6. Issuance: Seamless flow: issuing a digital tenge card via the backend with instant display in the app.
7. Transactions: Digital tenge transfers to other bank clients (P2P).
8. Conversion: Two-way exchange of digital tenge for non-cash fiat tenge and vice versa in real time.

Note: Card payments via POS terminals were handled by the bank; and our task was to prepare the infrastructure and the customer journey.

How Did We Handle the Tight Deadline?

The project’s main challenge lay not in the technology stack (which we have used for years), but in the strict timeline and the need for constant synchronization. With only weeks left before the presentation to the President, the cost of any error rises exponentially.

Our Delivery Management Approach:

We applied a hybrid Agile model with daily standups. Success was built on transparent communication established by IceRock Development. We did not wait for lengthy email approvals. Instead, we solved integration issues on the fly in a shared workspace with bank representatives. We acted not just as workforce to write code, but as a full-fledged technology partner managing risks. Pilot Launch and Results

One week before the deadline, we reached the pilot launch stage. Closed testing was conducted with a real but limited audience (the bank’s Friends & Family) to catch any edge cases during the crediting of actual social benefits.

Outcome: On November 15, 2023, Eurasian Bank successfully presented the case of receiving social benefits in digital tenge. The system performed flawlessly. The bank confirmed its status as a technology leader, while users gained a convenient and reliable tool for managing this innovative currency.

Key Takeaways for Business: Why Choose IceRock?

This case study clearly demonstrates: when a company’s reputation is on the line and deadlines are immovable, you need a partner with proven expertise.

Many outsourcing companies can build a mobile app. But only a few can dive deep into a bank’s architecture, grasp the nuances of interacting with government blockchain platforms, take full responsibility for project management, and deliver a ready-to-use enterprise product in just 2.5 months.

IceRock Development possesses comprehensive expertise in FinTech. If your company faces ambitious challenges in digital transformation, complex API integration, or high-load system development, we know how to deliver your project successfully on time.
