Organizational and Project Background
Eurasia Foundation (EF) is a US-based non-profit organization committed to helping citizens in countries in transition realize their full potential and transform their societies. EF supports governments and citizens to enhance responsive, accountable, and transparent governance, and helps citizens build a stronger, more resilient civil society.
Between 2018 and 2025, Ukraine made one of the most significant leaps in digital governance worldwide, increasing its UN Online Service Index score from 0.0594 to 0.9854 and becoming the regional leader in Eastern Europe and a top-30 global performer. This transformation was driven by the launch of Diia in 2020, the Ministry of Digital Transformation’s (MDT) flagship “super app” that integrates government services and digital documents. Diia has become a cornerstone of Ukraine’s digital public infrastructure, providing secure, citizen-centric, and corruption-resistant services that continued to operate even during the war, supporting millions of citizens. Ukraine’s digital success has attracted global attention as a model for citizen-focused transformation, yet replicating the Diia ecosystem can be challenging due to limited standardization and localization tools. Applying the GovStack Building Block approach can bridge these gaps by translating Diia’s architecture and governance into reusable components.
The activity outlined below is part of the Scaling Diia Globally: Diia Showcase and Digital Wallet Proof of Concept Project, which will support the Government of Ukraine’s strategic response to the growing international demand to learn from and adapt the Diia model. The Scaling Diia Globally Project is funded by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, Germany’s main international development agency. Through the Scaling Diia Globally initiative, EF will develop practical blueprints and process maps to help other countries plan and implement Diia-like digital public infrastructure. The project’s main workstreams include:
Diia Global Showcase: This workstream will map the Diia mobile application using the GovStack Building Blocks approach, documenting its architecture, governance, legal foundations, and key use cases. It will culminate in a Global Showcase Report and a communications package that positions Diia as a leading example of digital public infrastructure.
Digital Wallet Proof of Concept: This workstream will design, build, and validate a Digital Wallet prototype supporting issuance, secure on-device storage, presentation workflows, and verifier status checks, aligned with GovStack Wallet Building Block (BB) standards. It will include a technical documentation package and deploy the proof of concept in a GovStack Sandbox to test interoperability with other building blocks.
Request for Quotation
As part of the Scaling Diia Globally Project, EF invites your organization to submit a quotation for the following activity:
Activity Title:
Digital Wallet Proof of Concept Development
Type of Agreement:
Firm Fixed Price Contract
1. Objective of the Activity
The objective of this assignment is to design, document, and technically develop a Digital Wallet Proof of Concept (PoC) that demonstrates a secure, interoperable, and user-centric approach to managing and presenting digital credentials. The PoC will be developed in alignment with the GovStack Wallet Building Block standards and will be deployed in the GovStack Sandbox to validate interoperability with other digital public infrastructure components.
2. Scope of Work
The selected vendor shall be responsible for the end-to-end design, development, documentation, and testing of the Digital Wallet PoC in accordance with GovStack standards and project requirements.
The Digital Wallet PoC must be delivered as a functional Building Block that operates seamlessly on both iOS and Android mobile operating systems. The Building Block should be developed in accordance with GovStack Wallet Building Block specifications, including required backend services and APIs defined in the standard. The PoC must demonstrate core wallet functionalities, including issuance, secure storage, presentation, and verification of digital documents.
2.1 Activities
The vendor will perform the following tasks:
• Develop a functional Wallet Building Block PoC by adapting the open-source code of the Diia mobile application in alignment with GovStack guidelines, ensuring modularity and a structure suitable for future enhancement.
• Implement the core functions defined in the GovStack Wallet BB specification, including issuance, secure storage, management, and presentation of digital credentials or attributes, as well as support for basic verification workflows. The PoC should focus on demonstrating these essential lifecycle processes.
• Ensure interoperability with GovStack components relevant to the credential lifecycle, particularly the Identity Building Block and, where applicable, the Consent Building Block. Use standardized GovStack-compliant APIs and data-exchange mechanisms and validate integrations within the GovStack Sandbox.
• Apply an architectural approach consistent with GovStack principles—modularity, separation of concerns, and reusability of components—while leveraging structural elements of the Diia mobile application, where appropriate. The architecture should support further development beyond the PoC phase without requiring major redesign. The architecture should support deployment on both the Android and iOS mobile platforms, considering platform-specific constraints relevant to security, storage, and user experience.
• Implement baseline security controls consistent with GovStack guidelines, including secure local storage of credentials, the use of appropriate cryptographic mechanisms, support for secure authentication, and enforcement of authorization policies across the credential lifecycle.
• Align the user interface with GovStack UI/UX Guidelines and incorporate key design principles of the Diia mobile application to ensure a familiar, clear, and accessible user experience.
• Provide the PoC as installable Android and iOS builds to enable device-based evaluation and user experience review.
• Deploy the PoC in the GovStack Sandbox and conduct functional, interoperability, security, and performance testing consistent with GovStack evaluation practices. Prepare a testing report containing executed test cases, interoperability outcomes, identified issues or risks, and recommendations for improvement.
• Prepare a compliance evaluation package for the Wallet Building Block in accordance with the GovStack Compliance Evaluation Template. Additionally, prepare the PoC codebase and supporting materials in an open-source-ready format suitable for publication in GovStack repositories.
2.2 Technical Documentation
The vendor will prepare and deliver full technical documentation, including:
• Solution Architecture and System Component Description
• OpenAPI and Data Model Specification
• Security Architecture and Threat Model
• Deployment and Configuration Guide
• Admin and User Manual
• Software Requirement and API Testing Compliance Report
• Test Cases and Postman Collection
2.3 Showcase Communication Materials
a) Visual assets, diagrams, and slides describing the PoC architecture, core functionalities, and development process
b) Materials aligned with the Diia Global Showcase design and messaging guidelines
3. Expected Deliverables
The vendor will deliver the following:
• Functional Digital Wallet Building Block for iOS and Android mobile operating systems, aligned with GovStack specifications.
• Backend services, APIs, and data integration components required for PoC functionality.
• Comprehensive technical documentation, covering architecture, APIs, deployment, data flows, and testing.
• GovStack Sandbox testing completed, with a detailed interoperability and testing report, including compliance evaluation materials and preparation of the PoC codebase for publication in GovStack repositories.
• Showcase communication materials (visuals, slides, diagrams) for inclusion in the Diia Global Showcase package.
4. Implementation Period
The assignment is estimated to run between January 19, 2026 – April 17, 2026.
5. Quotation Requirements
Interested vendors are requested to submit:
• A technical proposal describing the team composition, methodology, tools, and experience relevant to the development the Diia mobile application or similar systems.
