How it works

ESMA publishes five MiCA registers as CSV files: crypto-asset service providers, e-money token issuers, asset-referenced token issuers, crypto-asset white papers, and entities flagged as non-compliant by national competent authorities. AssayDesk fetches those files on a daily schedule; ESMA itself republishes roughly weekly, so most days the file is byte-identical and nothing changes.

Every fetched file is archived with its SHA-256 hash before parsing, so any figure on this site can be traced back to the exact bytes ESMA served.

The register tables store ESMA's values verbatim — including truncated names, malformed dates, duplicated URLs and blank fields. Nothing is silently repaired on the way in. If a value looks wrong here, it looks wrong in the source, and that is information in itself.

One consequence worth knowing: ESMA publishes one CASP row per authorised service, so a firm appears once for each service it may provide. The sidebar counts entities; the register page shows the service rows.

Deterministic rules produce a display-ready value next to the raw one — a repaired link, a normalised date, a trimmed name. The rules are versioned and each correction records the rule that produced it. The original is always kept and always shown alongside; a correction is an annotation, never a replacement.

A weekly model review may add observations about suspicious records. It never writes a value. Model output is labelled unverified until a human confirms it.

The change history records what our sync observed between two published files: a record appeared, a field changed, a withdrawal date was published, a record vanished. Those are observations about the file, not statements about the firm.

In particular: a record disappearing from a CSV is not evidence that an authorisation was withdrawn — ESMA states withdrawals as a date column, and disappearances are usually publication artefacts. And absence from the register is not by itself proof that an entity is unauthorised; check the national register of the relevant member state.
