ECB Picks Telefónica and Minsait to Build the Digital Euro's Secure Backbone

How Telefónica and Minsait Won a Decade-Long Role in the Digital Euro

The European Central Bank has chosen Telefónica and Minsait, the technology arm of Spain's Indra, as one of two awardees to build the communications and cybersecurity layer that will underpin the future digital euro. The two companies have formed a consortium to design and deploy the networks and adjacent solutions the ECB needs, connecting the public and private intermediaries — banks, fintechs and payment service providers — that would take part in the digital currency.

The contract takes effect on 3 May 2027 and runs for ten years. It is not the only piece of the puzzle: the ECB also selected a consortium of Nexi Payments and Deutsche Telekom to deploy the digital euro's connectivity network, following a tender launched in August 2025. That rival contract began on 28 September 2026 to cover the pilot phase, while the Telefónica–Minsait work starts later. From 2029, both providers are expected to be ready to serve an eventual issuance of the currency, at which point banks and payment providers would be able to choose either platform to connect.

Technically, Telefónica's role covers communications infrastructure and its operation through units such as Telefónica Global Solutions and Telefónica Tech, including an MPLS private network, SD-WAN connectivity for multi-site networks and cybersecurity services. Minsait will supply the platforms and services that integrate applications, systems and participants via APIs, alongside digital identity, certificates and trust services through IndraMind Cybersecurity, all backed by a security operations centre designed to detect threats, control access and encrypt communications.

The digital euro is conceived as a digital payment method complementary to cash, accepted across the eurozone, and — according to the article — capable of supporting commercial transactions without an internet connection. That offline capability is one reason the underlying infrastructure is being described as critical and sovereign: it has to be robust, resilient and protected if it is to carry everyday payments at European scale.

Why the ECB Split the Work Between Two Consortia

The award structure is itself the story. Rather than hand the digital euro's plumbing to a single supplier, the ECB has divided it: Telefónica and Minsait take communications and security, while Nexi and Deutsche Telekom take the connectivity network. The staggered start dates — September 2026 for the pilot-phase contract, May 2027 for the ten-year one — suggest the ECB is sequencing build-out rather than committing everything at once. From 2029 both are meant to be service-ready, and banks and payment providers will be able to pick either platform. That redundancy is a deliberate design choice: for a system intended to sit alongside cash as public infrastructure, single-supplier dependence would be a structural vulnerability.

What Telefónica and Minsait Actually Bring

The division of labour maps closely onto each company's existing strengths. Telefónica contributes network assets and operations — MPLS, SD-WAN, data centres, cybersecurity — through Telefónica Global Solutions and Telefónica Tech, which is the kind of critical-network work it already sells to enterprises and governments. Minsait contributes the integration layer: APIs to connect applications and participants, digital identity, certificates, trust services via IndraMind Cybersecurity, and a security operations centre for threat detection, access control and encryption. In practice, the consortium is selling systems-integration and managed-security capability into a public financial infrastructure programme — a reference contract that is likely to matter more for future public-sector and regulated-industry tenders than for its direct revenue.

The Sovereignty Argument — and Its Limits

Both executives frame the win in strategic rather than commercial terms. Borja Ochoa describes it as a step in Telefónica's strategy of contributing to a more digital, secure and sovereign Europe; Luis Fernández calls the digital euro one of the most transformative technology and financial projects Europe is undertaking. That language reflects a real policy direction: European institutions have been pushing to reduce reliance on non-European payment and cloud providers in critical infrastructure. For context, the digital euro remains a project, not a launched currency — the ECB has not committed to issuance, and the article notes only that providers will be ready from 2029 should issuance happen. The contracts therefore fund preparation, not a live payment system.

What This Means for Banks, Fintechs and PSPs

The practical consequence for financial institutions is a choice architecture that will not exist for several years. Banks, fintechs and payment service providers are named as participants in the ecosystem, and from 2029 they would be able to connect through either the Telefónica–Minsait stack or the Nexi–Deutsche Telekom one. The offline transaction capability mentioned in the article — payments without an internet connection — is technically demanding and is one of the features most likely to shape how intermediaries design their integration. For now, the near-term signal is procurement: the ECB is building the rails in stages, and the suppliers that win these contracts position themselves for the integration work that follows if issuance proceeds.

What the Digital Euro Contract Means for Banks, Fintechs and PSPs

The digital euro is still a project, not a currency — but the ECB is now paying suppliers to build its plumbing, and the contracts run for a decade.

• Banks, fintechs and PSPs: note the two-platform structure. From 2029, when both providers are expected to be service-ready, participants would be able to choose between the Telefónica–Minsait stack and the Nexi–Deutsche Telekom network. Integration planning should assume a choice, not a single mandated rail.
• Watch the offline capability. The article states the digital euro is intended to support commercial transactions without an internet connection. That requirement drives much of the security and communications architecture being procured now, and it is the feature most likely to complicate intermediary-side integration.
• Suppliers and integrators: the ECB tender launched in August 2025 and has now produced two consortium awards with staggered start dates (28 September 2026 and 3 May 2027). Further workstreams around a possible issuance are the natural next procurement opportunities.
• Do not treat 2029 as an issuance date. It is the point at which providers are expected to be ready to serve an eventual issuance — the ECB has not committed to launching the currency.

Dates worth tracking: 3 May 2027 (start of the Telefónica–Minsait ten-year contract), the pilot phase already underway under the Nexi–Deutsche Telekom contract, and 2029 as the readiness milestone for both platforms.
