France proposes liability for crypto exchanges offering DeFi access

Markets in Crypto-Assets, or MiCA, is the European Union’s main crypto rulebook, and France is now testing how far that framework should extend into decentralized finance. The proposal sits at the point where regulated intermediaries meet DeFi products that are designed to operate without a traditional intermediary. It is being discussed now because France has put forward changes to how liability would work for platforms that connect users to those protocols.

For exchanges and other regulated platforms, the practical effect would be to examine how they offer DeFi access and how they handle losses tied to those services. Firms may need to change product design, disclosures, or risk controls if liability is attached to the customer experience around DeFi access. Users who prefer convenience through a regulated platform could find fewer offerings or tighter access conditions.

The case highlights a familiar crypto tension: regulators want clearer accountability when consumers use complex products, while DeFi’s appeal has been its open and disintermediated structure. Extending liability to the platform layer may make regulated access more cautious, but it also sits uneasily with the idea that DeFi can be used without the same gatekeepers as traditional finance. The result could be a sharper split between supervised venues and the more open, less supervised corners of crypto.

What remains open is how the EU would write the final liability standard and how broadly it would apply across member states and DeFi models. The reports do not say which losses would qualify, what defenses platforms could raise, or when the rule would take effect. Those details will determine whether the proposal becomes a narrow consumer-protection measure or a wider constraint on regulated DeFi access.
