EU MiCA Article 109: registers, white papers and what they actually show

MiCA's most underestimated artefact is not a recital. It is a register. Article 109 requires ESMA to maintain a public register of crypto-asset white papers, of issuers of asset-referenced tokens and e-money tokens, and of crypto-asset service providers. The accompanying technical standards push that data toward machine-readable classification by asset type. For the first time, the EU has a designed public interface between crypto-asset disclosure and market infrastructure.

What a white paper is under MiCA

A MiCA white paper is a prescribed disclosure document. For many crypto-assets it is notified, not authorised. For ARTs and EMTs the issuer-authorisation overlay is heavier. In all cases the paper is a claim-set with legal consequences for misleading content—not a prospectus in the EU prospectus-regulation sense, and not a guarantee that the competent authority has verified every technical or reserve statement.

National competent authorities remain the operational front door. The Dutch AFM's public materials on white-paper supervision are a useful illustration: the NCA process is real, documented, and still not a substitute for reading the issuer's legal entity, its reserve arrangements, and its group structure.

How to use the register as evidence

• Presence on the register supports a claim that a white paper or authorisation was notified through an NCA at a date.
• Classification fields support a claim about how the asset was characterised for the filing.
• Absence is a lead, not a conclusion: notification timing, grand-fathering and perimeter disputes all create blanks.
• The register does not, by itself, identify beneficial owners, smart-contract upgrade keys, or custody banks.
