EU Proposes Certification Rules for Non-Custodial Bitcoin Wallet Developers
European Union regulators are conducting a review of the Markets in Crypto-Assets (MiCA) framework, which includes a proposal to require non-custodial Bitcoin wallet developers to secure certification before distributing their software to the public.
As part of the consultation, the European Securities and Markets Authority (ESMA) clarified that open-source software development, self-custodial tools, automated smart contracts, and permissionless systems should not automatically be classified as regulated intermediaries. In addition, ESMA recommended establishing a distinct regulated service category for crypto asset service providers that offer retail clients access to decentralized protocols.
Existing regulatory standards remain unchanged for now. The European Commission plans to evaluate feedback gathered during the review process and present a formal report under Article 140 of MiCA by June 30, 2027.
