A MiCA crypto-asset white paper is the mandatory EU disclosure you must prepare, notify to the competent authority and publish before any public offer or admission to trading of a crypto-asset in the Union. Until that happens, you cannot market the token, make a public offer, or admit it to trading, save for specific exclusions. The accountable actors are the issuer, the offeror or the person seeking admission to trading, alongside trading-platform operators that control listings and face related duties under the regime (MiCA).
The mandatory MiCA white paper: who must publish it and when it gates an offer
MiCA creates a pre-offer and pre-admission gate. Before any public offer or any step to admit a crypto-asset to trading in the EU, the responsible party must draw up the disclosure document to MiCA standards, notify it to the national competent authority (NCA) and publish it. The duty sits with the issuer or offeror for public offers, and with the person seeking admission when planning a listing. Trading platforms control admissions and are part of the accountability chain, including through civil-liability provisions and transitional listing duties. MiCA carves out explicit exclusions, but where the regime applies the gate is hard: no compliant document, no marketing, offer or admission (MiCA).
Required disclosures and the standardised format
Article 6 and Annex I set the core content for “other crypto-assets,” with parallel schedules for ARTs and EMTs. The paper must be dated, include a table of contents and be written so that retail readers can understand it. MiCA requires it to be “fair, clear and not misleading,” concise and comprehensible, and to be made available in a machine‑readable format specified in Level‑2 measures (MiCA).
Annex I components for the disclosure include:
- Details of the issuer/offeror/person seeking admission and any trading‑platform operator involved in the process
- The project and the terms of the offer
- The crypto‑asset’s characteristics and any rights or obligations attached
- The underlying technology and its functioning
- Risk factors material to holders
- Principal sustainability impacts, for example climate impacts linked to the consensus mechanism
The European Commission’s Implementing Technical Standards lock in the structure and files teams must produce. Commission Implementing Regulation (EU) 2024/2984 prescribes standard forms and templates and requires a structured, machine‑readable submission, including iXBRL elements. Legal, product and engineering teams should expect to map each Annex I item to the ITS template fields and generate the mandated file package.
Notification clocks by token type—and what “publish” means in practice
Timing depends on the token category. For many tokens, the responsible party must notify the NCA ahead of publication; for e‑money tokens, MiCA explicitly requires notification at least 20 working days before publication. In contrast, asset‑referenced tokens and some credit‑institution cases trigger longer, more formal supervisory interactions that include assessment or approval timelines, with procedures that can run up to 90 working days. In the simpler notification tracks, authorities are informed and can engage, but they do not “approve” the document before it goes live. In the longer tracks, firms should plan for iterative feedback and potential conditions before publication proceeds (MiCA).
Publish does not just mean posting a PDF. Under the Level‑2 ITS, the white paper must be made publicly available in the standardised, machine‑readable format that matches the regulation’s forms and templates. Teams should align their launch date with both the upstream notification clock and the downstream operational work of generating iXBRL/structured files, hosting them for public access and providing them to the NCA in the manner it prescribes (Implementing Regulation 2024/2984).
What you can and cannot market until the white paper is live
MiCA draws a clear line between internal planning and public solicitations. No marketing communications may be disseminated before the disclosure document is published. Once you do communicate, additional conditions apply to what you say and how you say it (ESMA, Article 29).
- Marketing must be clearly identifiable as such and align with the information in the document; no embellishments that contradict or outpace the disclosure.
- Include a statement that a MiCA crypto‑asset white paper has been published and provide contact details.
- Publish the marketing communications on the issuer’s website so they are accessible alongside the disclosure record.
Liability for the information you publish
MiCA attaches civil liability to the information in the document. Issuers and offerors, persons seeking admission to trading, operators of trading platforms and the members of their management bodies can be liable to holders for losses caused by information that is incomplete, unfair, unclear or misleading. Any contractual attempt to exclude or limit that liability is void (ESMA, Article 15).
Walkthrough example: notifying a white paper to the AMF (France)
National procedures operationalise the EU rules. The French Autorité des marchés financiers (AMF) publishes a practical, email‑based process for notifying a white paper. It illustrates the standard upstream notice and how to handle updates (AMF guidance).
- Send the notification to the AMF via the dedicated email channel, following the format the AMF specifies for subject line, attachments and contact information.
- Notify the AMF sufficiently in advance of publication, meeting the standard pre‑publication notice window referenced in MiCA and reflected in AMF practice.
- If you modify the document after notification, inform the AMF promptly; the AMF guidance sets out short deadlines for communicating changes before going live.
- After publication, keep the AMF informed of material updates according to the AMF’s procedure and MiCA’s update obligations.
Registers and transitional dates that still govern live operations
Once published, the disclosure does not vanish into a drawer. NCAs register white papers and the European Securities and Markets Authority (ESMA) will host a central register under Article 109, creating a searchable supervisory record for the market (MiCA).
Transitional measures are equally operational. Marketing and publication rules apply to communications made after 30 December 2024. Member‑state authorities may publish practical notification and registration procedures to help firms navigate these obligations (MiCA).
By 31 December 2027, EU trading platforms must ensure any already‑admitted token has a MiCA‑compliant white paper on file or prepare for removal decisions.
Frequently Asked Questions
Do NCAs approve every MiCA white paper before publication?
No. For many tokens, firms notify the authority ahead of publication without a formal approval step. Certain asset‑referenced tokens and some credit‑institution cases involve longer assessment or approval procedures.
What exactly counts as “publication” under MiCA?
Making the disclosure available to the public in the standardised, machine‑readable format specified by Implementing Regulation 2024/2984, and in line with any practical instructions from your NCA.
Can we run teaser ads or waitlists before the document is live?
No public marketing communications can be disseminated until the document is published. After publication, marketing must be clearly identifiable, consistent with the disclosure and include the mandated statement and contact details.
Is a white paper required for a secondary listing of an existing token?
Admission to trading is a trigger. If the regime applies, a compliant document is required. For tokens already admitted, platform operators must ensure compliance by 31 December 2027.
Who is liable if the document contains errors or omissions?
Issuers/offerors, persons seeking admission, trading‑platform operators and members of their management bodies can be civilly liable to holders. Contractual waivers of that liability are void.
How should we address sustainability impacts?
Include principal sustainability impacts as required by Annex I, such as climate effects associated with the consensus mechanism, and present them in the standardised template.
