Under the EU’s Markets in Crypto-Assets Regulation (MiCA), most crypto-assets offered to the public or admitted to trading in the EEA need a standardized crypto-asset white paper, notified to a national competent authority (NCA) and published. OKX, for example, requires a MiCA-compliant white paper for EEA listings, submitted to an NCA at least 20 business days before the target listing date, using the official EU templates, including ESG (sustainability) disclosures, and filed in machine-readable format.
Key takeaways
- MiCA white papers follow official EU templates; they are not free-form marketing documents.
- OKX: submit to an NCA ≥20 business days before the target EEA listing date; the countdown starts at submission.
- Include ESG/sustainability indicators and file in machine-readable format (ESMA template).
- The approved white paper is published on ESMA’s register and on the exchange’s EU site.
The process OKX describes
| Step | What it involves |
|---|---|
| 1. Timeline | Submit the completed white paper to an NCA at least 20 business days before the target listing date; the countdown starts on submission |
| 2. Draft | Use the official EU template for crypto-assets other than ARTs and EMTs; follow ESMA/EBA explanatory notes; include ESG data |
| 3. Machine-readable filing | Use ESMA’s XLSM template with exact field formats (dates, numbers, no “N/A” placeholders where a data type is required) |
| 4. Submit and prove | Submit to the NCA; give the exchange official proof of submission |
| 5. Consent to publish | Allow the exchange to publish the white paper on its EU website |
Practical tips
- Start early. Drafting, ESG data, and machine-readable formatting take longer than most teams expect.
- Use counsel familiar with the chosen NCA.
- Keep statements factual. The white paper carries legal liability; avoid promotional language.
- Reuse across exchanges. One compliant white paper can support listings on several EEA venues, subject to each exchange’s process.

Frequently asked questions
Do all exchange listings need a MiCA white paper?
For trading available to users in the EEA under MiCA, generally yes for crypto-assets other than those excluded by the regulation. Listings outside the EEA are governed by other rules. Check with the exchange and counsel.
Who submits the MiCA white paper?
The project team or its legal counsel submits it to a national competent authority in an EU member state; OKX mentions examples such as MFSA (Malta), AMF (France), and BaFin (Germany). The exchange needs proof of submission.
What happens if we miss the 20-business-day deadline?
According to OKX, if the deadline is missed or the white paper is not compliant, the EEA listing has to be postponed.
