MiCA White Paper Errors: Common Mistakes, Legal Risks & How to Fix Them

Handling a MiCA white paper error is a “drop everything and fix it” moment for any crypto entrepreneur. Whether it is a miscalculation in your tokenomics, a change in your consensus mechanism, or a failure to disclose a conflict of interest, an uncorrected mistake is a direct liability trigger for you and your management team.

If you have identified an inaccuracy in your published documentation, you must act immediately. The regulatory framework provides a specific protocol for amendments, but the window to act is narrow. This guide details the legal risks of MiCA white paper errors, the strict timeline for corrections, and how LegalBison can assist you in navigating this critical process.

The liability trap: Why accuracy is non-negotiable

The most significant shift MiCA (Markets in Crypto Assets) introduces is the formalization of civil liability. Under Article 15 of the Regulation, the stakes for providing incorrect information are incredibly high.

Personal liability for management

It is not just the corporate entity that is at risk. MiCA explicitly states that the “offeror, person seeking admission to trading or operator of a trading platform and the members of its administrative, management or supervisory body shall be liable to a holder of the crypto-asset for any loss incurred” due to infringements.

This means that as a founder or director, your personal assets could potentially be at risk if the white paper contains information that is not “complete, fair or clear” or if it is “misleading”. This applies to the initial white paper and any modified versions you publish later.

No disclaimers allowed

Many crypto projects attempt to shield themselves with elaborate “legal disclaimers” at the bottom of their websites. Under MiCA, these are largely ineffective regarding the core content of the white paper.

Article 15(2) is unequivocal: “Any contractual exclusion or limitation of civil liability… shall be deprived of legal effect”. You cannot contract your way out of the obligation to tell the truth. If an investor proves that they relied on misleading information in your white paper to make a purchase decision and suffered a loss as a result, the issuer is liable.

The burden of proof

While the burden of proof lies with the holder of the crypto-asset to demonstrate that the information was misleading and that they relied on it, the sheer volume of mandatory disclosures in Annex I (for utility tokens) or Annex II (for asset-referenced tokens) creates a vast surface area for potential errors. A white paper audit is the only way to ensure every claim is substantiated and legally defensible.

The “7-day” update protocol: How to amend your white paper

If you discover a “material mistake” or a “material inaccuracy,” or if a “significant new factor” arises that affects the assessment of the crypto-assets, you cannot simply upload a new PDF to your server. You must follow the strict modification procedure outlined in Article 12 of MiCA.

Step 1: Identify the trigger

You are legally required to modify your white paper whenever there is a change capable of affecting the assessment of the crypto-assets. This requirement applies for the entire duration of the public offer or as long as the token is admitted to trading. Common triggers include:

• Changes to the project roadmap or milestones;
• Changes in the management team or advisors;
• Modifications to the underlying protocol or consensus mechanism;
• Updates to the reserve of assets (for ARTs and EMTs);
• Discovery of a technical error in the smart contract.

Step 2: Notify the National Competent Authority (NCA)

You must notify your modified white paper to the competent authority of your home Member State. Crucially, this notification must happen at least seven working days before publication.

The notification must include:

• The modified crypto-asset white paper;
• The intended publication date;
• The reasons for the modification.

For example, if you are registered in France, you must notify the AMF. If you are in Germany, you notify BaFin. Failing to respect this 7-day window constitutes a procedural breach of the regulation.

Step 3: Inform the public immediately

While you wait for the 7-day period to elapse, you cannot stay silent. On the date of publication (or earlier if the regulator requires it), you must inform the public on your website that a modified white paper has been notified. You must also provide a summary of the reasons for the update.

Step 4: Version control and timestamps

MiCA demands rigorous version control. The modified white paper must be time-stamped. The most recent version must be clearly marked as the “applicable version.”

Furthermore, you cannot simply delete history. Older versions of the crypto-asset white paper must remain publicly available on your website for at least 10 years after the date of their publication. These archival versions must carry a prominent warning stating that they are no longer valid and include a hyperlink to the current version.

Technical compliance: iXBRL and machine readability

Amending a white paper is not just a text-editing exercise; it is a coding exercise. Article 6(10) mandates that the crypto-asset white paper “shall be made available in a machine-readable format”.

ESMA is tasked with developing implementing technical standards (ITS) to establish standard forms and formats for this purpose. This implies that your white paper must likely be formatted in Inline XBRL (iXBRL), a standard that allows regulators and investors to parse data automatically.

When you amend MiCA whitepaper content, you must also update the underlying machine-readable data tags. A misalignment between your human-readable PDF and your machine-readable iXBRL file could lead to the rejection of your filing or a public warning from the NCA. This technical layer adds complexity to the correction process, making professional legal and technical assistance essential.

Consequences of inaction

Ignoring an error or delaying an update is a dangerous strategy. The penalties under MiCA for infringing the rules on white papers (Articles 4 through 14) are severe.

National Competent Authorities have the power to take immediate administrative measures, including:

• Suspension: Suspending the offer to the public for up to 30 consecutive working days;
• Prohibition: Prohibiting the offer entirely if they find the regulation has been infringed;
• Public Censure: Making public the fact that the issuer is failing to fulfill its obligations.

Beyond operational disruptions, the financial penalties are substantial.

For legal persons, fines for infringing Title II (white papers for utility tokens) can reach at least 5,000,000 EUR or 3% of total annual turnover. For issuers of Asset-Referenced Tokens (ARTs), the penalties can escalate to 12.5% of annual turnover for certain infringements.

When to seek a legal opinion

Determining whether an error is “material” can be subjective. Is a 2-week delay in a roadmap milestone “significant”? Is a change in a marketing partner “material”?

If you are unsure, you need a Legal Opinion. A formal legal opinion analyzes the specific discrepancy in your white paper against the definitions in Article 12 and Article 6. It provides a documented rationale for why an update is (or is not) required, which can serve as a defense of “good faith” if a regulator later questions your decision.

Furthermore, if you are dealing with notifying NCA of white paper amendments, having a lawyer draft the “reasons for modification” ensures that you do not inadvertently admit to a compliance failure when simply correcting a typo.
