Digital Euro on Ethereum or Solana: A Threat or Opportunity for Europe’s Monetary Sovereignty?
The Digital Euro on Ethereum or Solana could redefine Europe’s monetary sovereignty, but it also raises pressing concerns about privacy, governance, and the balance of global financial power.
As U.S. dollar-backed stablecoins gain momentum, European policymakers are being forced to accelerate their own digital currency strategy.
Europe Rethinks Its Digital Euro Strategy
European officials are debating whether to issue the digital euro on public blockchains like Ethereum or Solana, moving away from initial plans for a closed, centrally controlled system. The shift comes in the wake of the U.S. passing its first stablecoin law in July, giving the dollar an early advantage in the global digital asset race.
Ram Kumar, a core contributor at blockchain infrastructure firm OpenLedger, said that deploying the euro on a public chain would instantly broaden its reach.
“It would open the euro to the wider crypto economy instantly,” Kumar told Decrypt. “It could plug into DeFi, global wallets, and cross-border payments without needing to build that infrastructure from scratch.”
Ethereum could provide “programmability and access to a rich developer ecosystem,” Kumar explained, while Solana offers “low fees and high throughput that can handle consumer-scale payments.”
The U.S. Pushes Europe Into Action
Kumar noted that the U.S. stablecoin law, dubbed the GENIUS Act, is putting pressure on Europe.
“If the dollar gets a head start in digital payments, it risks overshadowing the euro in global finance,” he said.
The Financial Times recently reported that officials are seriously weighing the use of public blockchains, marking a significant departure from earlier proposals.
Risks of a Public Blockchain Euro
Despite the potential benefits, a digital euro on Ethereum or Solana raises serious risks.
Privacy Concerns: Public blockchains conflict with the EU’s GDPR framework, which includes rights such as data erasure. Ensuring cash-like anonymity in digital payments remains a top priority for the European Central Bank (ECB).
Technical Challenges: Ethereum’s scalability limits and Solana’s history of outages highlight vulnerabilities in relying on external blockchain networks.
Governance Issues: Validators and upgrades would remain outside direct state control, raising sovereignty concerns.
Banking Stability: Policymakers warn that if widely adopted, a digital euro could siphon deposits from banks, destabilizing Europe’s financial system.
In April, ECB executive board member Piero Cipollone warned that U.S. stablecoins could erode European bank deposits and strengthen the dollar’s global dominance. He reiterated those concerns in July, stressing that Europe’s financial stability and strategic autonomy were at stake.
When Could the Digital Euro Launch?
An ECB spokesperson confirmed to Decrypt that its timeline remains unchanged. The bank believes a digital euro could be technically ready within two-and-a-half to three years after enabling legislation is in place.
Still, the debate shows that Europe is under pressure to adapt quickly. With the U.S. aggressively promoting crypto-assets and dollar-backed stablecoins under Trump’s administration, the euro risks being left behind in the battle for digital monetary dominance.
Bottom Line
The Digital Euro on Ethereum or Solana could be Europe’s chance to remain competitive in the new era of digital money. But the trade-off between global reach and sovereign control is stark. As policymakers weigh their options, the decision will shape not just Europe’s monetary future, but also its role in the global balance of financial power.
