- EU officials are assessing whether a digital euro could run on Ethereum or Solana public blockchains.
- No decision has been taken as privacy, throughput and supervision questions remain under review.
The European Union is evaluating whether to issue a digital euro on public blockchains such as Ethereum or Solana, marking a potential shift away from the private infrastructure previously favored by policymakers.
Brussels weighs public-chain deployment to widen access while responding to US policy
Officials in Brussels and at the European Central Bank are examining whether a public blockchain base layer could support a retail digital euro with broad interoperability and developer access.
The reassessment follows recent US legislative momentum around stablecoins, which has sharpened concerns about euro relevance in digital payments and cross-border commerce.
While the choice of platform remains open, the discussion now explicitly includes Ethereum and Solana alongside permissioned alternatives.
Authorities have framed the work as technology-neutral, with the ECB continuing to test multiple architectures. A public-chain option would rely on well established validator networks and tooling while aiming to preserve central bank control over issuance and redemption. Officials stress that no decision has been made on issuance, network selection or launch timing.
A public deployment would need to coexist with Europe’s regulatory framework, including MiCA and payments rules, and avoid disintermediating commercial banks. The ECB has reiterated that any digital euro would be convertible one to one with cash and designed for instant settlement at point of sale.
Supervisors test privacy safeguards and operational constraints before any platform choice
Policy teams are evaluating privacy models that could separate identity from transaction data while allowing law enforcement access under due process. That assessment spans wallet limits, offline payment options and data-minimization requirements, which are central to previous ECB consultations.
The public-chain option also raises questions on throughput, finality, censorship resistance and energy use, all of which need to be reconciled with central bank service levels.
Precedents for institutional use of public chains have informed the analysis. The European Investment Bank issued a €100 million two-year digital bond in 2021 using Ethereum technology, demonstrating operational workflows for issuance and settlement with regulated intermediaries.
Subsequent EIB transactions have continued to test wholesale settlement mechanisms in coordination with Eurosystem pilots.
If the EU were to choose a public network, the implementation would likely involve a permissioned token contract and dedicated governance to control minting, redemption and blacklist functions while leaving base-layer consensus to the network.
Integration with existing rails, including SEPA instant and card acceptance, would be essential to reach consumers and merchants at scale. The ECB’s stance indicates that each of these components remains under study and subject to formal decision by European lawmakers and the central bank’s Governing Council.
At the time of this press, ETH is $4,645.48, up +9.16% over the past 24 hours, having traded between $4,209.91 and $4,656.13 in that period.
