Trembita.gov.ua – report for the 1st quarter of 2025

The DT4UA project presents the first quarterly report in 2025 on the work of Trembita, the system of electronic interaction of state electronic information resources in Ukraine. Trembita remains the key infrastructure for secure data exchange between government agencies, providing citizens and businesses with fast access to digital services.

Key achievements:

• 2.5+ billion transactions in the system per quarter (the highest quarterly figure in Trembita’s history);
• 278 system participants;
• 179 electronic information resources (EIRs) connected;
• 1,075 web services, of which 381 are active;
• The total number of transactions since launch has exceeded 12+ billion.

The slogan and essence of Trembita: ‘Data should run, not people!’

“Trembita enables the transfer of data from various state registers so that people receive the services they need. The basis of this system is the advanced Estonian data exchange platform X-ROAD, which is the foundation of the Estonian digital society and has been redesigned for the needs of Ukraine with the help of the European Union projects EGOV4UKRAINE (2016-2021), EU4DigitalUA (2020-2024) and DT4UA.

Electronic interaction is the process of data exchange between two electronic information resources through the software systems of the recipient (web clients) and the supplier (web services). A transaction in the Trembita system is a completed cycle of sending an electronic request message from a web client to a web service, processing it by the web service, receiving an electronic response message from the web service by the web client, and then processing it by the web client.

DT4UA’s contribution

In Q1 2025, the DT4UA project continued to play a key role in the development of the Trembita system. The project team provided comprehensive technical support, including the development of new web services and web clients for government agencies, updating the Trembita Catalogue, and implementing digital interactions for agencies such as the Ministry of Veterans Affairs, the State Tax Service, and the Ministry of Internal Affairs. DT4UA experts also provided advice on assessing the development of the system based on indicator analysis and conducted a series of training events that reached more than 180 government officials. Thanks to the project’s support, Trembita not only maintained stable operation in wartime, but also continued to expand its functionality and improve the quality of electronic interaction.

Statistical data for the 1st quarter of 2025:

The analysis also shows that, in addition to interactions with Diia, interactions are also established between other EIRs, with the largest number of transactions between:

Electronic cabinet of conscripts, persons liable for military service and reservists – Register of conscripts, persons liable for military service and reservists: over 62.3 million transactions. The interaction is aimed at ensuring the functioning of the Reserve+ mobile application.

Electronic Healthcare System – State Register of Individual Taxpayers: over 53.4 million transactions. This interaction provides for the provision and verification of an individual’s registration data processed by the State Register of Individual Taxpayers.

Register of Conscripts, Persons Liable for Military Service and Reservists – Register of Insured Persons: over 47.7 million transactions. This interaction ensures verification of the place of employment of persons liable for military service.

Automated information system of educational management – State Register of Civil Status Acts: over 34.2 million requests. The interaction is set up to receive data on child birth certificates.

Analysis of the connection of the main registers to the Trembita system:

* – connected to the test environment of the Trembita platform.

** – as an information resource of the UIS of the MIA.

The analysis of the List of priority state electronic information resources for the introduction of electronic interaction, which is specified in the Resolution of the Cabinet of Ministers of Ukraine No. 606 of 08 September 2016 ‘Some issues of electronic interaction of electronic information resources’, showed minor changes in the first quarter of 2025 in the direction of setting up information interactions of priority state electronic information resources, namely, it is clear that out of 21 registers

– 19 registers are connected to the industrial environment of the Trembita platform, while the Unified Register of State Property Objects is connected to the test environment, the Register of Value Added Tax Payers is not yet connected;

– 18 of the 19 connected registers have electronic information interactions, except for the Unified State Register of Vehicles, but only 17 have active web services.

The Trembita system demonstrates high rates of development, as evidenced by the steady growth in the number of participants, EIRs and transactions. Thanks to the support of the DT4UA project, it was possible not only to maintain the system’s performance during the war, but also to ensure its high-quality upgrade. In 2025, Trembita will continue to be the backbone of digital interaction in Ukraine.
