The European Securities and Markets Authority (ESMA) has ordered crypto-asset service providers operating in the EU without authorization to shut down key parts of their business as the MiCA transitional period expires on July 1.

According to NS3.AI, firms that lack authorization must stop taking new EU clients, cease marketing activities, and block new account openings.

ESMA said existing services may continue only to support offboarding and risk-reduction actions, including allowing clients to sell assets, transfer holdings, close positions, or leave the platform.
