MiCAR white papers in iXBRL format are due on 23 December. But ESMA warning disclaims liability if your iXBRL white paper contains inconsistencies with the MiCAR ITS.
In the rapidly evolving landscape of crypto-asset regulation, the European Securities and Markets Authority (ESMA) has issued critical guidance to support the implementation of the Markets in Crypto-Assets Regulation (MiCAR).
Effective from December 23, 2025, MiCAR mandates that issuers, offerors, and crypto-asset service providers (CASPs) publish white papers in Inline XBRL (iXBRL) format, ensuring machine-readable disclosures for oversight, transparency and investor protection. This includes detailed classifications of crypto-assets, risk factors, and operational details, all formatted per the XBRL taxonomy released on August 5, 2025.
Non-compliance isn’t just a paperwork oversight — it’s a gateway to severe penalties, including fines up to 12.5% of annual turnover or €5 million for individuals, as outlined in MiCAR’s enforcement provisions. With ESMA poised to ramp up supervisory actions, the stakes for accurate, validated disclosures have never been higher.
At the heart of ESMA’s recent statement lies a stark warning that underscores the perils of cutting corners. To illustrate iXBRL white paper generation, ESMA provides a voluntary Excel-based example on its website. However, the accompanying ESMA warning and disclaimer is chilling:
“Its use is voluntary and ESMA will not accept any liability concerning its use or its outputs, which need validation and remain under the full responsibility of the issuer/CASP.”
This isn’t mere boilerplate — it’s a deliberate signal from the regulator itself. The ESMA warning explicitly distances itself from any errors, omissions, or inaccuracies in the tool’s outputs, placing the full burden of validation squarely on market participants.
Relying on a sample tool provided by a regulator risks producing flawed filings that fail to meet the rigorous standards of Commission Implementing Regulation (EU) 2024/2984, (MiCAR ITS). Outputs could misalign with the white paper ITS Annex, leading to untraceable tagging errors in XHTML or incomplete machine-readable fields for asset classification under Delegated Regulation (EU) 2025/421.
This ESMA warning exposes a fundamental flaw in ad-hoc approaches to MiCAR compliance: sample tools from regulators are just that — samples, not certified solutions. Without robust validation mechanisms, issuers and CASPs could inadvertently submit non-compliant white papers, inviting ESMA scrutiny. And scrutiny breeds expensive enforcement. MiCAR empowers national competent authorities (NCAs), coordinated by ESMA, to investigate breaches with powers akin to those under MiFID II. Fines aren’t hypothetical; they’re a revenue stream for regulators strained by emerging tech oversight and EU Commission budgets.
Historical precedents from ESMA’s sustainable finance disclosures show fines totaling over €100 million in recent years for similar tagging failures. Under MiCAR, this creates a lucrative enforcement opportunity: each validated violation funds further regulatory expansion, turning compliance lapses into a predictable income source. Why gamble when the house — ESMA — always wins?
