The MiCA white paper register: what notification means, and what it does not

This article is for informational purposes only and does not constitute legal advice. Consult a qualified legal professional for advice specific to your situation.

What the register covers, and what it does not

The ESMA register established under Article 109 of MiCA is a public record of four distinct things: white papers for crypto-assets other than asset-referenced tokens and e-money tokens; issuers of asset-referenced tokens; issuers of e-money tokens; and crypto-asset service providers. These are not variations of the same regulatory event. They sit under different titles of MiCA and reflect processes with meaningfully different levels of regulatory scrutiny before the issuer appears in the register.

The MiCA White Papers Directory draws on the white papers portion of the register. When you see an issuer listed with a notified competent authority and a link to their white paper, that entry tells you the issuer completed a notification procedure with a national regulator. It does not tell you the regulator reviewed the document, approved its contents, or confirmed that the token is classified correctly.

How the notification process works for non-stablecoin crypto-assets

For issuers of crypto-assets other than asset-referenced tokens or e-money tokens, the procedure under Article 8 of MiCA is a notification, not an authorisation. The issuer must submit the white paper to the competent authority of their home Member State at least 20 working days before publication, along with an explanation of why the crypto-asset is not an ART, an EMT, or an asset otherwise excluded from MiCA's scope. The competent authority receives this package, but Article 8 expressly states that competent authorities shall not require prior approval of crypto-asset white papers before their publication.

This means the timeline runs forward from notification to publication, not backwards from a regulatory sign-off. The regulator may have supervisory powers after the fact, but the white paper can go live once the notification window has passed. Appearing in the ESMA register for this category of issuer confirms the notification was made; it says nothing about the regulator's view of the content.

Why the ART process is different

For issuers of asset-referenced tokens, the picture is more demanding. A non-credit institution seeking to issue an ART must apply for authorisation under Article 16 of MiCA, and the white paper forms part of that authorisation package under Article 19. The competent authority has 25 working days to assess whether the application is complete, and a further 60 working days to assess the application itself. A credit institution issuing an ART instead follows the dedicated procedure under Article 17, which requires notification and white paper submission at least 90 working days before the first issuance, and gives the ECB and relevant national central banks a formal role, including the ability to block issuance if they identify risks to monetary policy transmission or monetary sovereignty.

The practical implication is that when an ART issuer appears in the ESMA register, the white paper linked there has gone through a substantively different process than those of the non-stablecoin issuers sitting alongside them in the same interface. Treating the register as a uniform list obscures this distinction.

The interim register and what it means for how you use this tool

ESMA was required by Articles 109 and 110 of MiCA to have the register operational by 30 December 2024. To meet that deadline, it built an interim version distributed as CSV files and updated on a weekly basis, with the expectation that it would eventually be integrated into ESMA's permanent IT infrastructure. The data depends on national competent authorities communicating relevant changes to ESMA, which means the register reflects what NCAs have passed on, not necessarily everything that has been notified at the national level.

This matters for how to read a search result from the tool. An issuer not appearing in the directory does not necessarily mean they have not notified a white paper. It may mean the relevant NCA has not yet communicated the data to ESMA, or that the update cycle has not yet captured a recent notification. Equally, an issuer appearing in the register for a jurisdiction does not mean that jurisdiction's regulator has vetted their documentation in any substantive sense.

What notification does and does not protect

The absence of a prior-approval requirement does not leave the regime without teeth. MiCA imposes liability on issuers for the accuracy of their white papers. Misleading information, material omissions, and incorrect classification carry legal consequences regardless of whether a regulator reviewed the document before publication. Issuers are also required to update their white papers when any significant new factor, material mistake, or material inaccuracy arises that could affect the assessment of the crypto-asset.

For those using the register to assess an issuer, the practical question is not whether the white paper was approved. It is whether the content of the document holds up on its own terms, whether the token type classification is credible, and whether the issuer is meeting their ongoing obligations, including the obligation to update. A white paper that was notified two years ago may not reflect the current state of the project. The register records the notification history but does not track whether updates have been made and notified in turn.

Note on the "Article 42" reference

The tool's header references Articles 8, 17, and 42. Based on the primary text, Article 8 covers notification for other crypto-assets, Article 17 covers the credit institution ART pathway, and the EMT white paper notification procedure sits in Article 51, with the broader EMT requirements in Title IV starting at Article 48. Article 42 of MiCA concerns own-funds requirements for ART issuers rather than white paper notification. It is worth verifying what the underlying data source intends by that citation before publishing, or describing the register by token type category rather than article number to avoid the ambiguity.
