EU Chat Control Revival Puts Encrypted Wallets and Web3 Messaging on Notice

The European Parliament is set to vote on Thursday on whether to extend, until 2028, a temporary framework permitting online platforms to scan private messages for child sexual abuse material — a proposal that blockchain industry figures warn could extend compliance burdens to encrypted crypto wallets and decentralised messaging tools. According to Euronews, MPs approved a rarely used urgent procedure on Tuesday to schedule the fresh vote after the underlying legal basis lapsed in early April.

The procedural motion passed narrowly, with 331 votes in favour, 304 against and 11 abstentions, Euronews reported. Because the measure was revived through the urgent procedure, any rejection or amendment on Thursday would now require an absolute majority of 361 votes — a considerably higher threshold than the simple majority that defeated a similar extension in March.

A contested return to Parliament’s agenda

Pirate Party MEP Markéta Gregorová said the move revived a proposal Parliament had already rejected earlier in the year, describing the use of the urgent procedure to reopen it as unprecedented, according to Euronews. The report said the proposal’s return followed backing from the European People’s Party, the chamber’s largest political group, with party leader Manfred Weber reportedly seeking a route to advance the measure without the amendments that had narrowed its scope and contributed to the March defeat.

Separately, EU member states agreed last month to restore an interim version of the framework, allowing service providers to detect, report and remove abuse material voluntarily until 2028. Since the previous legal basis expired in April, platforms including WhatsApp have continued such detection on a voluntary basis rather than under a binding EU framework, Euronews noted.

Why crypto firms are watching closely

For digital asset businesses, the stakes extend beyond consumer messaging apps. If lawmakers reinstate the scanning framework, Web3 projects offering wallet-based messaging or decentralised social features may need to introduce content-monitoring systems or withdraw those services from EU users to remain compliant, according to the report.

Some industry participants have voiced concern that the legal reasoning underpinning client-side scanning could eventually be extended to blockchain transaction data or smart contract infrastructure, raising the prospect of surveillance obligations reaching further into decentralised finance and non-custodial wallet architecture than currently contemplated.

Privacy advocates and cryptography specialists, including Ethereum co-founder Vitalik Buterin, have criticised the broader push for mandatory scanning on grounds that it could undermine end-to-end encryption. The crypto sector’s objection centres on the practical mechanics of client-side scanning: any system built to inspect message content before encryption risks creating a structural vulnerability that could be exploited well beyond its intended purpose, according to industry critics cited in the report.

A compliance question still unresolved

Thursday’s vote will not settle the matter permanently. The extension under discussion is explicitly temporary, pending negotiation of a durable law, meaning crypto platforms operating wallet messaging or social layers in the EU face continued regulatory uncertainty regardless of the outcome.

For an industry already navigating the bloc’s Markets in Crypto-Assets regime, the chat control debate adds a further compliance dimension — one that touches encryption architecture rather than financial disclosure, and one that firms with EU-facing messaging features will need to monitor closely as the permanent framework is negotiated.
