MiCA White Paper Rules: The Gate Before Any Token Offer

A crypto project that wants to raise money or list tokens in the European Union has a new compulsory step before it can say a word in public. The MiCA regulation requires a white paper – a disclosure document written to a specific EU standard – that must be notified to a national authority and published before any public offer or trading admission. Skipping it means no marketing, no offer, no listing.

The party responsible is the issuer, the offeror or whoever seeks admission to trading. Trading platforms control listings and face their own duties under the regime, including civil-liability provisions and transitional obligations for tokens already admitted. The gate is hard: no compliant document, no activity.

Article 6 and Annex I set the content for "other crypto-assets." Parallel schedules apply for asset-referenced tokens (ARTs) and e-money tokens (EMTs). The paper must be dated, have a table of contents and be written so retail readers can follow it. MiCA demands it be "fair, clear and not misleading," concise and comprehensible, and available in a machine-readable format defined in Level 2 measures.

Annex I requires detailed disclosures about the project, the rights attached to the token and the associated narratives. The European Commission's Implementing Technical Standards lock in the structure. Commission Implementing Regulation (EU) 2024/2984 prescribes standard forms and templates, including iXBRL elements. Legal, product and engineering teams need to map each Annex I item to the ITS template fields and generate the mandated file package.

Timing varies by token category. For most tokens, the responsible party notifies the national competent authority (NCA) before publication – a notification step, not an approval step. For e-money tokens, MiCA requires notification at least 20 working days before publication. Asset-referenced tokens and some credit-institution cases trigger longer supervisory interactions with assessment or approval timelines that can run up to 90 working days. In the notification tracks, authorities are informed and can engage, but they do not sign off before the document goes live. In the longer tracks, firms should plan for iterative feedback and potential conditions.

Publishing does not mean posting a PDF on a website. The white paper must be made publicly available in the standardised, machine-readable format matching 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 or structured files, hosting them for public access and providing them to the NCA in the manner it prescribes.

MiCA draws a firm line between internal planning and public solicitation. No marketing communications may be disseminated before the white paper is published. Once published, additional conditions apply to what you say and how you say it.

Civil liability attaches to the disclosure. Issuers and offerors, persons seeking admission to trading, operators of trading platforms and 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.

National authorities operationalise the EU rules in their own ways. The French Autorité des marchés financiers (AMF), for example, publishes a practical, email-based process for notifying a white paper. It illustrates the standard upstream notice and how to handle updates.
