Millions of EU citizens currently send messages through systems that scan them, according to policy experts who warn that end-to-end encryption sits next in line for regulatory scrutiny. The current rules stem from a derogation to the ePrivacy directive, which lawmakers extended in July 2026 to run until April 2028.
EU Chat Control and Broad Technical Access
Vyara Savova, senior policy lead at the European Ethereum Institute, points out a key distinction between two files often merged by critics. The first allows providers to scan voluntarily, while the second would turn scanning into a legal duty. Because most large platforms already use the voluntary route, EU message scanning functions as a current default rather than a future risk.
Although the legal purpose may target specific content, the technical mechanism requires checking the entire message. Ethereum co-founder Vitalik Buterin highlighted this revival as a cybersecurity risk in July, noting that apps utilizing end-to-end encryption cannot comply with this logic without first decrypting the traffic.
Implications for Crypto Users and Digital Privacy
The broader digital enforcement toolkit in Brussels also includes scrutiny of virtual private networks as potential loopholes in age verification rules. For cryptocurrency users, the exposure is distinct, as wallet recovery flows, seed phrase backups, and trading group chats frequently utilize standard consumer messaging apps, with file storage also falling within the same regulatory scope.
While voluntary scanning covers a narrow category of material, a mandatory approach could apply the same machinery to all conversations without suspicion. Proponents of the rules, including child protection groups and European Commission officials, argue that platforms already hold the data and that the goal remains limited to addressing abuse material.
However, legal experts like Marina Markezic, co-founder and executive director of the European Ethereum Institute, emphasize that constitutional principles regarding privacy should still apply regardless of whether access is physical or digital. As upcoming negotiation rounds approach in the autumn, users are advised to consider apps that publish clear encryption models and to move sensitive files away from standard consumer chat applications.
