On Friday, the European Securities and Markets Authority (ESMA) published a consolidated statement outlining the data standards and technical formats that will apply under MiCA. While some of these requirements have been discussed separately in various ITS/RTS, this is the first time we’ve seen them brought together in a single document.
The statement covers several areas that will directly shape how issuers and CASPs prepare for compliance, including:
The XHTML/iXBRL format for crypto-asset white papers;
JSON and ISO 20022 standards for order-book, transaction and record-keeping data;
Transparency and reporting data requirements for trading platforms; and
Mandatory LEIs and DTIs to ensure consistent identification of entities and digital assets.
These technical standards aim to harmonise data quality across the market, support supervisory oversight, and ensure interoperability between market participants. In short, MiCA is now machine-readable, end-to-end.
At Eunice, we’re already supporting clients in aligning onboarding, documentation and reporting workflows with these requirements: from preparing iXBRL-ready white papers to helping CASPs organise the structured data needed for submissions and transparency.
