The proposed digital currency represents an electronic version of cash issued directly by the ECB, designed to serve as a public-facing anchor for the financial system. While physical notes will remain in circulation, the ECB views this digital alternative as a necessary evolution to maintain monetary sovereignty against the rise of cryptocurrencies and the dominance of U.S.-based payment giants like Visa and Mastercard. Unlike current digital funds, which function as claims on commercial banks, the digital euro would be a direct claim on the central bank.

To prevent the mass flight of deposits from the traditional banking sector, the ECB intends to cap individual holdings at 3,000 euros and will not offer interest on these balances. While consumers will access the currency free of charge via dedicated apps or specialized payment cards, the infrastructure costs remain a point of contention with commercial banks. The ECB maintains that its payment standards will be provided to financial institutions at no cost, though banks argue that the system upgrades required to support the new currency warrant further compensation.

Privacy remains a central pillar of the design, with the ECB promising that it will not monitor individual transaction data. For standard online payments, commercial banks will handle data similarly to existing digital methods. An offline mode is also in development, which would allow users to conduct transactions without an internet connection, ensuring that details remain private and only the resulting balance changes are recorded.
