Woofun AI reports that the European Securities and Markets Authority (ESMA) has launched a common supervisory action (CSA) to evaluate the operational resilience of crypto-asset service providers (CASPs), with a specific mandate to scrutinize crypto custody providers. This regulatory initiative emerges directly after the conclusion of the Markets in Crypto-Assets (MiCA) framework’s transition period, signaling a shift from legislative implementation to active enforcement oversight.

The review scope is defined by national competent authorities (NCAs) across the EU, which will examine a risk-based sample of authorized entities starting now. The assessment period extends through the first half of 2027, during which regulators will inspect critical operational domains including key and storage management, governance structures, and transaction controls. Per Woofun AI, the audit also targets incident detection and response protocols, as well as dependencies on external service providers, ensuring comprehensive coverage of custody-related vulnerabilities.

Structurally, this supervisory push addresses lingering enforcement questions that surfaced as MiCA’s transition phase ended. The timing coincides with industry adjustments, such as BitGo launching a Europe-focused crypto-as-a-service platform last month to help firms navigate these new compliance requirements. This market response highlights the immediate pressure on service providers to align their infrastructure with the stringent operational standards now being enforced by EU authorities.

ESMA will consolidate the NCAs’ findings into a final report for its Board of Supervisors in the second half of 2027. This process establishes a rigorous benchmark for operational resilience frameworks within custody activities, marking a definitive move toward standardized regulatory oversight in the European crypto sector.
