France proposes liability for crypto exchanges offering DeFi access
French authorities have proposed that crypto exchanges be required to conduct due diligence on decentralized finance (DeFi) protocols and accept liability for certain customer losses as part of changes to incoming EU crypto rules. The proposal would extend obligations for market intermediaries beyond traditional token listings, seeking to hold platforms responsible when they provide users direct access to DeFi services.
What the proposal would change
The core element of the French proposal is to place a compliance and liability burden on centralized venues that facilitate user interaction with DeFi protocols. Under the proposed framework, exchanges would be expected to perform checks on the smart contracts and counterparties that their customers interact with, and could be held accountable for losses arising from interactions deemed to be within their scope of responsibility. The measure is framed as a way to strengthen investor protections amid growing retail and institutional engagement with noncustodial DeFi products.
Why this matters for markets and infrastructure
The proposal touches on several core issues in crypto market structure. By attaching liability to access, regulators would effectively blur the line between custodial centralized services and permissionless DeFi. This could prompt exchanges to limit or alter the way they offer DeFi interfaces, shift users toward fully custodial products, or develop new risk controls for smart contract interactions. Market infrastructure providers such as custody firms, liquidity venues and broker-dealers may need to reassess operational workflows and contractual protections with clients and counterparties.
For major digital assets, the practical effects could differ. DeFi activity is concentrated on smart-contract platforms such as Ethereum, so any reduction in exchange-facilitated access could affect on-chain liquidity, DEX volumes and the flow of ETH used for collateral or gas. Bitcoin, which has comparatively limited native DeFi use, may see less direct impact, though cross-chain and wrapped asset use could be affected where exchanges re-evaluate services involving wrapped BTC or other tokenized representations.
Institutional participants and asset managers assessing regulated product launches — including ETFs, custody mandates and prime brokerage services — will monitor how liability rules influence counterparty risk and the feasibility of offering integrated DeFi exposure. Higher compliance and legal costs could slow product development or push firms to favor tightly controlled, custodial structures over permissionless exposures.
At the same time, the proposal raises broader questions about innovation and decentralization. Imposing centralized compliance obligations on intermediaries for interactions with permissionless protocols could incentivize the creation of intermediate products that replicate DeFi economics within regulated wrappers, changing where liquidity and innovation occur.
Market participants will likely watch how the proposal is refined as it moves through EU legislative channels, and whether other member states or the European Commission adopt similar stances. Key aspects to monitor include the definition of "providing access," the scope and triggers for liability, required due diligence standards, and transitional provisions for existing services.
Next, market actors will be tracking regulatory text revisions, industry responses, and guidance on implementation. Exchanges, custodians, institutional investors and DeFi projects will also be watching enforcement intent and practical compliance timelines to assess operational and market-structure impacts.
