The Bank of Spain has put out to tender a contract of up to €78 million to develop the infrastructure for the digital euro, the largest outlay committed to date by the Spanish supervisor for this project.
The Bank of Spain has published a tender on the State Contracting Platform worth up to €78 million to build the technical infrastructure for the digital euro. This is not a pilot or a proof of concept: it is the largest public contract in Spain linked to the Eurosystem's digital currency.
The tender, divided into several lots, covers consultancy services, software development, payment gateway integration, and usability testing with real users. The awarded companies will need to work with the technical standards that the European Central Bank (ECB) is defining in Frankfurt, and the first deliverables must be ready before the end of 2027.
Consumer testing and accelerated timeline
One of the most visible milestones of the contract will be consumer testing. A group of employees from the Bank of Spain will make purchases at a selection of partner shops using a mobile application that will emulate the future digital euro wallet. The aim is to identify failures in real environments before a potential national pilot phase, a strategy that other central banks have already tested.
The move by the Spanish supervisor is not isolated. The ECB recently announced the selection of 36 payment companies —including the Galician entity ABANCA— for a pan-European pilot of the digital euro that will measure its performance against instruments such as dollar-denominated stablecoins. The speed at which the private digital payments ecosystem is gaining ground has been the main catalyst for this acceleration.
Stablecoins, crypto-assets that replicate the value of fiat currencies like the dollar, have shifted from being a marginal experiment to moving daily volumes exceeding $150 billion in their main networks. The European Commission and the ECB fear that a slow-to-implement digital euro will leave the micropayments and cross-border transfers space in the hands of private issuers, mostly American.
The sprint for the digital euro is no longer theoretical: €78 million on the table and the public contracting machinery operating at full capacity.
Impact on banking and consumers
What is at stake is not just monetary sovereignty. For commercial banks, the emergence of the digital euro could disrupt their main source of funding: sight deposits. A design that allows citizens and businesses to hold balances directly at the ECB —albeit limited, as authorities propose— would erode part of the banking liability and make credit more expensive. The treasury teams of major Spanish entities are closely monitoring every detail of the technical specifications.
For consumers, the digital euro promises instant payments without fees and a layer of privacy superior to what current cards offer, although the ECB has made it clear that it will not be completely anonymous to comply with anti-money laundering regulations. The balance between traceability and personal data protection remains one of the most contentious points of the design.
The Bank of Spain's contract comes at a time when the fragmentation of payment systems in the EU is evident. While in China the digital yuan is already used in millions of shops, in Europe discussions about privacy, holding limits, and distribution models have delayed the project for years. ECB leaks suggest that the final version of the digital euro may not be operational until 2029.
A megacontract that sets a position
The €78 million tendered by the Bank of Spain doubles the budget allocated to any other equivalent initiative within the Eurosystem during the research phase, which formally concludes in October 2026. This budget advance indicates that Frankfurt has given the green light for national central banks to start moving forward without waiting for all political loose ends to be resolved.
The technology companies competing for the contract include both European giants and strategic consulting firms with experience in modernising payment infrastructures. The most lucrative lots —backend development and security— are valued together at over €45 million, making the award one of the most relevant technology contracting processes in the Spanish public sector in 2026.
From the fintech trenches, the reading is ambivalent. A digital euro operated by the Eurosystem could become an almost unbeatable competitor, but also an open platform on which to build innovative services, provided the APIs are generous enough. Much will depend on the fine print accompanying each lot of the megacontract.
The Bank of Spain has marked a milestone by putting €78 million on the table. Now, the ball is in the court of the technology companies and the ECB, who must demonstrate that the digital euro can be more than just a laboratory experiment.
