ECB Seeks Industry Input to Build Digital Euro’s Real-World Infrastructure
As the European Central Bank (ECB) moves from conceptual design toward practical implementation of a potential digital euro, it is actively recruiting technical experts to help shape how the central bank digital currency (CBDC) will function in everyday commerce. In a significant step announced Wednesday, the ECB opened applications for specialists to join two dedicated workstreams under its Rulebook Development Group (RDG), focusing on the critical physical and technical layers of the future payment system.
This call for industry expertise underscores a pivotal phase in the digital euro project: defining the precise mechanics of integration. The ECB is not just designing a digital currency; it is engineering its seamless coexistence with Europe’s existing payment landscape. The work will address how a digital euro would operate at points of sale—specifically through ATMs and payment terminals—while also establishing the rigorous certification processes needed to ensure security and interoperability across the continent.
Two Critical Workstreams Target Hardware and Standards
The ECB has delineated two distinct but interconnected areas requiring deep technical knowledge:
First, an implementation specifications workstream will focus on the needs of ATM and terminal providers. Experts in this group will tackle concrete challenges, including the communication technologies required for transactions, the development of robust offline functionality (a key feature for resilience), and the strategic reuse of existing, widely-adopted European payment standards. The goal is to minimize disruption and cost for merchants and banks by leveraging current infrastructure where possible.
Second, a certification and approval frameworks workstream will develop the testing, certification, and approval processes for all payment solutions and infrastructure within the digital euro ecosystem. This work is essential for payment service providers (PSPs) who will need to comply with new rules. It will establish the “quality seal” for hardware and software, ensuring uniformity, security, and consumer trust across all EU member states.
Both workstreams will report to the RDG, a multi-stakeholder body that includes representatives from merchants, PSPs, and consumer groups. Selected experts are expected to provide direct, technical input to support the development of a comprehensive and standardized rulebook—the foundational document that will govern the digital euro’s operational details.
Pathway to a 2027 Pilot and Final Decision
The formation of these expert groups aligns with the ECB’s previously stated timeline. The institution aims to select a cohort of EU-licensed payment service providers ahead of a limited-scope, 12-month pilot phase. As ECB Executive Board Member Piero Cipollone confirmed on February 18, this pilot is scheduled to begin in the second half of 2027 and will involve a controlled group of merchants, Eurosystem staff, and PSPs testing the digital euro in real-world conditions.

It is crucial to note that the ECB has consistently maintained that a final decision to issue a digital euro will only be taken after the necessary EU legislation is formally adopted by the European Parliament and Council. The current workstreams are therefore part of extensive preparation, ensuring that if the political green light is given, the technical and operational foundation is ready for a swift and orderly rollout.
Context: A Measured Approach in a Global CBDC Landscape
Europe’s approach to a CBDC has been characterized by thorough analysis and a strong emphasis on privacy, offline capabilities, and interoperability—principles that are now being translated into specific technical requirements. By engaging directly with ATM manufacturers, terminal developers, and standards bodies, the ECB is addressing one of the most complex challenges of any CBDC: physical distribution and merchant acceptance.
This contrasts with some other global CBDC projects that are further along in retail testing. The ECB’s deliberate pace, anchored in the Rulebook Development Group’s collaborative model, reflects a commitment to building a system that is not only innovative but also stable, secure, and harmonized across the diverse economies of the Eurozone. The success of the 2027 pilot will hinge on the specifications being developed by these very workstreams.
