ECB Taps Stripe, Revolut and 34 Payment Firms for Landmark Digital Euro Trial

Europe’s digital currency project is moving out of policy papers and into the payment terminal. The European Central Bank has selected 36 payment service providers, including Stripe, Revolut, Adyen, Deutsche Bank and UniCredit, to participate in a year-long digital euro pilot beginning in the second half of 2027.

The trial will test whether a digital form of central bank money can function reliably across the everyday situations that determine whether a payment system succeeds or disappears: sending money to another person, tapping a phone at a physical checkout and completing a purchase inside an online store.

For the ECB, this is a major shift from designing the digital euro in theory to testing how it behaves across banks, fintech applications, merchant systems and central bank infrastructure. For the selected payment companies, it offers an early look at what could become one of the most consequential changes to Europe’s retail payment architecture in decades.

A public launch remains conditional, however. The ECB has not made a final decision to issue the digital euro and says it will do so only after European lawmakers adopt the necessary regulation. Assuming the legal framework is completed as planned, the central bank wants to be ready for a possible first issuance during 2029.

Stripe and Revolut Join a Broad Payments Coalition

The inclusion of Stripe and Revolut gives the pilot two participants with substantial influence over Europe’s digital commerce economy.

Stripe supplies payment infrastructure to online businesses ranging from early-stage startups to international platforms. Its involvement places the digital euro directly inside discussions about checkout conversion, merchant integration, refunds, fraud controls and cross-border e-commerce.

Revolut brings a different advantage. The company operates a consumer-facing financial application used across multiple European markets, giving it experience in mobile wallets, rapid account onboarding and cross-border money movement. Its presence could help the ECB understand whether the digital euro can be presented as an intuitive consumer product rather than merely another settlement option hidden behind a banking interface.

The group is considerably broader than those two companies. It includes payment processors Adyen, Nexi, Worldline, SumUp and PAYONE, alongside established banking groups such as Deutsche Bank, DZ Bank, UniCredit, BPCE, Monte dei Paschi di Siena, National Bank of Greece and Raiffeisen Bank International.

Fintech providers including Satispay and traditional postal and retail banking operators such as Poste Italiane are also represented. The result is a testing group that spans large commercial banks, digital banks, merchant acquirers, payment gateways and regional financial institutions.

That diversity is deliberate. The ECB received more than 50 applications and selected participants according to their regulatory eligibility, technical readiness, geographical footprint and ability to support different payment scenarios. Rather than building the pilot around a small group of dominant banks, the Eurosystem is attempting to reproduce the fragmented reality of the European payments market.

What the 2027 Pilot Will Actually Test

The operational phase is scheduled to begin in the second half of 2027 and run for 12 months. Before that happens, participating companies will spend the development period connecting their systems to the digital euro service platform, building customer-facing payment services, testing interfaces and completing technical certification.

The trial will use a beta digital euro that is designed to resemble the proposed final system as closely as possible. It will not be legal tender, and participating consumers will not be opening personal accounts directly with the ECB. Instead, payment service providers will remain the primary interface between users and the Eurosystem.

Some participants will act as distributing providers. They will give eligible users access to beta digital euro services, support account setup and enable payments. Others will act as acquiring providers, connecting merchants to the system so they can receive digital euro transactions. Several companies will perform both functions.

The pilot will focus on four practical payment flows.

Participants will test online person-to-person transfers using identifiers that allow one user to send funds to another remotely. They will also test offline person-to-person transactions through near-field communication, enabling two devices to transfer value by being tapped together without either device requiring an active internet connection.

Physical merchants will accept online digital euro payments through NFC-enabled systems, including software-based point-of-sale applications that can turn compatible phones or tablets into payment terminals. E-commerce and mobile-commerce merchants will test the digital euro as a checkout method for purchases made through websites and applications.

These scenarios are significant because they extend beyond basic account transfers. The ECB is testing whether the digital euro can operate as a genuine retail payment instrument across both physical and digital commerce.

The Pilot Is Controlled, but the Transactions Are Real

The trial will not initially be open to the general public. Individual users will primarily be employees of the ECB and participating euro-area central banks. Selected restaurants, cafeterias, physical shops and e-commerce businesses will act as merchants.

Testing will take place at the ECB and 19 national central banks across the euro area. This controlled structure will allow the Eurosystem to observe transaction performance, user behavior and operational failures without exposing the broader public to an unfinished system.

Even within that restricted environment, the pilot is expected to generate valuable information. The ECB wants to determine whether the infrastructure is robust, scalable and sufficiently simple for everyday use. It will also evaluate onboarding, settlement, liquidity management, customer support, refunds and incident handling.

Offline payments may prove particularly important. A digital euro that can move between devices without internet access could offer resilience during network failures and provide a more cash-like experience than existing card or wallet systems. It also presents some of the most difficult technical challenges, including preventing duplicate spending, securing funds stored on devices and synchronizing transaction records when users reconnect.

The pilot will therefore test more than transaction speed. It will examine whether the proposed system can survive the messy conditions of real commerce, where devices lose connectivity, refunds are requested, customers make mistakes and merchants depend on immediate confirmation that a payment has succeeded.

Europe’s Push for Greater Payment Sovereignty

The digital euro is partly a response to Europe’s dependence on payment infrastructure controlled by companies headquartered outside the region.

European consumers may use domestic banks and local financial applications, but many card and online transactions still rely on international networks. The ECB believes a common digital euro infrastructure could provide a European payment option that works across the entire currency union.

The project is not designed to eliminate banks, card networks or private wallets. The ECB’s model keeps payment service providers in front of the customer, allowing banks and fintech companies to build interfaces and additional services around central bank infrastructure.

In that sense, the digital euro resembles a public payment rail rather than a government-operated retail bank. The central bank would provide the underlying form of money and core platform, while private companies would compete over applications, customer service and merchant tools.

That division of responsibilities explains why the selection of Stripe, Revolut and other major providers matters. A digital currency can be technically sophisticated and still fail if merchants do not integrate it, consumers find it inconvenient or payment companies treat it as a regulatory burden.

The 2027 pilot is intended to discover those problems before any national rollout begins.

What Participation Means for Stripe, Revolut and the Banks

The selected firms will not be paid by the Eurosystem for joining the test. They are expected to cover their own development and operational costs, and they will not be permitted to charge participating consumers or merchants for pilot-related services.

Their incentive is strategic rather than immediate.

Participation gives each company early experience with the digital euro’s technical interfaces, liquidity processes, compliance requirements and customer journeys. Some of that infrastructure may be reusable if the ECB proceeds with a broader rollout, potentially giving pilot members a head start over providers that wait until the final system is approved.

For Stripe, the pilot could shape how the digital euro appears in online checkout flows and how merchants integrate it alongside cards, bank transfers and digital wallets. For Revolut, it offers a chance to test how central bank digital money fits inside a consumer financial application already designed around multiple currencies and payment methods.

Banks face a more complicated calculation. A successful digital euro could give them access to common European payment rails, but it could also introduce costs and alter how consumers hold and transfer money. Policymakers are expected to use holding limits and other safeguards to prevent large movements of deposits from commercial banks into digital central bank money.

The trial will give banks an opportunity to assess those risks using working systems rather than theoretical models.

A Digital Euro Is Not a Cryptocurrency or Stablecoin

Despite the digital terminology, the proposed euro would not function like Bitcoin, Ether or a privately issued stablecoin.

Cryptocurrencies generally operate on decentralized or distributed networks, with prices determined by markets. Stablecoins are typically digital tokens issued by private organizations and designed to track the value of currencies such as the euro or dollar.

The digital euro would instead represent public money issued through the Eurosystem. Its value would remain equal to the physical euro, and it would be designed primarily for payments rather than speculation or investment.

The project nevertheless arrives at a time when stablecoins are becoming increasingly important in international digital finance. Dollar-denominated tokens dominate crypto trading and are expanding into remittances, settlement and commercial payments. That growth raises a strategic question for European policymakers: whether the euro can remain influential in digital markets without a widely available public digital form.

A digital euro would not automatically displace stablecoins. It could, however, give European consumers and businesses another option for moving euro-denominated value through digital channels without relying on a private token issuer.

The 2029 Launch Is Still Conditional

The selection of payment providers does not mean the digital euro has received final approval.

The ECB’s ability to issue the currency depends on the completion of the European Union’s legislative process. The final regulation will determine important questions concerning privacy, holding limits, merchant acceptance, provider compensation and the division of responsibilities between central banks and private institutions.

Only after that framework is adopted will the ECB decide whether to issue the digital euro.

The current timetable assumes the legislation will be completed in time for development work and the 2027 pilot to proceed toward a potential 2029 launch. Delays or major changes to the regulation could alter the design or push the schedule back.

The pilot itself may also reveal problems that require further engineering. The initial 12-month period can be extended by as much as six months if additional validation is needed.

That uncertainty is not a weakness in the process. It is the purpose of the trial. Europe is attempting to determine whether a digital form of public money can work at continental scale without undermining financial stability, privacy or competition.

Europe’s Digital Currency Enters Its Decisive Phase

The most important signal from the ECB’s announcement is not simply that Stripe and Revolut are participating. It is that the digital euro is approaching the point where political ambition must survive contact with payment terminals, banking systems and consumer expectations.

The project now has a group of companies capable of testing nearly every layer of the retail payment chain. Traditional banks can evaluate account management and liquidity. Digital banks can experiment with mobile access. Acquirers can test merchant acceptance. Payment processors can examine e-commerce integration and transaction performance.

By the end of the pilot, the ECB should have a much clearer picture of whether the digital euro can offer something Europe’s existing payment methods do not: a widely accepted, resilient and pan-European form of digital central bank money.

A 2029 launch is far from guaranteed. But with 36 payment providers preparing to build and test the system, the digital euro is no longer merely a proposal. It is becoming payment infrastructure.
