On 20 June 2025, the Bulgarian Parliament adopted the new Markets in Crypto-Assets Act (MCAA), which enters into force on 8 July 2025. This national legislation complements the EU’s MiCA Regulation (Regulation (EU) 2023/1114) by establishing the local legal and institutional framework for the regulation of crypto-assets in Bulgaria. The MCAA designates the competent authorities responsible for authorisation and supervision of crypto-asset service providers (CASPs) and introduces additional national requirements related to documentation, oversight, and sanctions for non-compliance. The article outlines the key provisions of the new law and its implications for market participants.
