The MiCA regulation is the common European framework for issuing covered crypto-assets and providing regulated crypto services.
For British businesses trying to understand MiCA, the practical answer depends on customer location, marketing activity and the legal entity performing each service. MiCA is EU law, and it can reach UK firms that solicit clients in a member state, issue tokens for EU market or operate through a European group entity. Legal Entity Identifiers also appear in specific MiCA applications, white paper data and public registers. LEI24 helps companies obtain and manage them where the relevant process requires one.
What Is the MiCA Regulation?
MiCA stands for Markets in Crypto-Assets. Regulation (EU) 2023/1114 on markets in crypto-assets establishes common rules for crypto-assets that are outside existing financial services legislation.
The MiCA regulation covers public offers, admission to trading, token disclosures and defined crypto-asset services. It also sets requirements for authorisation, governance, client asset protection, complaints, conflicts of interest, prudential safeguards and market abuse controls.
Assets already governed by another financial regime remain under that regime. A token that qualifies as a financial instrument may fall under securities law, and deposits, structured deposits and securitisation positions sit outside MiCA. Legal classification decides which rules apply to the issuer, the offer and the related services.
MiCA Timeline: Key Dates and the End of Grandfathering
MiCA entered into force on 29 June 2023, with its obligations arriving in stages. The provisions for asset-referenced tokens and e-money tokens began to apply on 30 June 2024, followed by the remaining main provisions, including CASP authorisation, on 30 December 2024.
Existing providers could continue under national transitional arrangements where a member state permitted them. Some countries allowed the maximum period, others introduced shorter arrangements, and some offered no transition. The final possible period ended on 1 July 2026. ESMA’s position on the end of MiCA transitional periods explains the consequences for firms that continued under previous national regimes.
Grandfathering is now closed. Registration under a previous national regime no longer authorises a firm to provide MiCA crypto-asset services.
Who Does MiCA Apply To?
MiCA applies to issuers, offerors, persons seeking admission to trading and providers of regulated crypto-asset services in the EU. Scope depends on the asset, activity, customer location and entity performing the work.
Within one group, one company may issue a token, another may operate the platform and a third may contract with customers. Each role requires a separate assessment because authorisation and responsibility follow the entity performing the regulated activity.
Crypto-Asset Service Providers (CASPs)
A crypto-asset service provider, or CASP, is an undertaking that professionally provides regulated crypto services. These include custody, operating a trading platform, exchanging crypto-assets, executing or transmitting orders, providing advice, portfolio management and transfer services.
Most firms need authorisation from the competent authority in their home member state. A CASP licence belongs to the named legal entity and covers only its approved services. Certain regulated financial institutions can use the Article 60 notification route for activities permitted by their existing authorisation.
Token Issuers and Offerors
MiCA can apply to the issuer, offeror and person seeking admission to trading, whether those roles sit with one company or several entities.
Asset-referenced token issuers generally need authorisation unless an exemption applies. E-money tokens can usually be offered to the public or admitted to trading only when the issuer is a credit institution or electronic money institution. Offerors of other crypto-assets may need to prepare, notify and publish a crypto-asset white paper, subject to exemptions for certain small offers, qualified investors and tokens linked to existing goods or services.
Does MiCA Apply to UK Crypto Firms?
A UK crypto firm cannot actively provide MiCA services to EU clients through a UK entity merely because it is incorporated or FCA-authorised in Britain. Outside MiCA’s narrow reverse-solicitation exception, it will generally need to serve those clients through a legal entity established and authorised in an EU member state.
Article 61 provides a narrow reverse solicitation exception where the client acts entirely on their own initiative. ESMA’s criteria for reverse solicitation under MiCA treat advertising, affiliates, influencers, sponsorships, events and retargeting as possible evidence of solicitation. Disclaimers cannot override active marketing.
Group structures also require care because the authorised entity remains responsible for regulated services and each outsourced function must comply with MiCA.
How MiCA Classifies Crypto-Assets
MiCA divides covered crypto-assets into three main categories according to their design, rights and economic function. The name chosen by the project carries limited weight.
Classification starts by asking whether another financial regime applies. A token that qualifies as a financial instrument may instead fall under MiFID II rules for financial instruments and investment services. The remaining analysis distinguishes e-money tokens, asset-referenced tokens and other crypto-assets.
E-Money Tokens (EMTs)
An e-money token seeks to maintain a stable value by referencing one official currency. A token linked to sterling, the euro or the US dollar can fall within this category when it meets the legal definition.
The issuer must generally be authorised as a credit institution or electronic money institution. Holders have a claim against the issuer and a right to redeem at par value in the referenced currency.
Asset-Referenced Tokens (ARTs)
An asset-referenced token seeks to maintain a stable value by referencing another value or right, or a combination of values or rights. The reference can include currencies, commodities, crypto-assets or a basket of assets.
A token linked to several currencies or a mixed basket may qualify as an ART. Issuers face requirements covering authorisation, governance, own funds, recovery planning and redemption. Reserve assets must be managed, segregated, held and invested in accordance with MiCA.
Other Crypto-Assets (Including Utility Tokens)
This category covers crypto-assets that are neither ARTs nor EMTs, including many utility tokens, exchange tokens and project tokens that do not qualify as financial instruments.
A utility token provides access to a good or service supplied by its issuer. Exemptions may apply where the good or service already exists or the offer stays within specified limits. Genuinely unique and non-fungible assets sit outside MiCA, while fractionalised interests, large collections and interchangeable tokens require closer assessment.
Key Requirements Under MiCA
MiCA compliance depends on the role performed by the business and can include authorisation, disclosure, governance, custody, complaints, outsourcing, record keeping and market abuse controls.
The Crypto-Asset White Paper
A crypto-asset white paper is the main disclosure document for an offer or admission to trading. It identifies the issuer or offeror and explains the project, token, offer, attached rights, technology, risks and principal adverse environmental effects of the consensus mechanism.
The content must be fair, clear and not misleading. It must not contain assertions about the future value of the crypto-asset. Marketing communications must remain consistent with the white paper and be clearly identifiable as promotional material.
For crypto-assets other than ARTs and EMTs, the usual process is notification to the competent authority, subject to any exemption. Prior approval is generally unnecessary. Standardised formatting and machine-readable data requirements also make accurate entity names, identifiers and token data part of the filing.
CASP Authorisation and EU Passporting
A CASP application covers the applicant’s legal structure, ownership, management, programme of operations, governance, controls, prudential safeguards, complaints process, conflicts policy, outsourcing, custody arrangements and information technology systems.
The competent authority assesses the firm’s management, resources and operating presence. Authorisation covers the named entity and approved services, so additional services require an extension of permission.
An authorised provider can passport those services into other member states through the prescribed notification process. Local tax, consumer, advertising, anti-money laundering and employment rules may still apply.
Stablecoin Reserve and Redemption Rules
ART issuers must maintain reserve assets supporting the token, with rules covering composition, segregation, custody, management and investment. Token holders also receive redemption rights under MiCA.
EMT issuers must safeguard funds received for tokens, and holders can redeem at par value at any time. Significant ARTs and EMTs face additional obligations and closer supervision based on factors such as scale, use and links to the financial system.
Market Abuse and Conduct Rules
MiCA prohibits insider dealing, unlawful disclosure of inside information and market manipulation in relation to crypto-assets admitted to trading, or for which a request for admission to trading has been made.
Issuers must disclose inside information that directly concerns them, subject to the conditions for delayed disclosure. Relevant firms also need systems for detecting and reporting suspicious orders and transactions. CASPs must act honestly, fairly and professionally, manage conflicts, protect client assets, keep records and maintain complaint procedures.
MiCA vs the UK’s Emerging Crypto Regime
MiCA governs covered activity in the EU, and domestic UK activity sits within the UK’s own legal framework. The FCA application process and timetable for the new UK cryptoasset regime explain how the authorisation gateway will operate.
The UK model brings specified cryptoasset activities into the Financial Services and Markets Act framework. The application period is scheduled to run from 30 September 2026 to 28 February 2027, and the regime is expected to commence on 25 October 2027. MiCA uses separate token categories and a CASP authorisation structure, so its permissions, disclosures and stablecoin rules differ.
A British group serving both markets may need an FCA-authorised UK entity and a separately authorised entity in a member state. No shared passport connects the systems, and contracts, websites, product terms and marketing controls must identify which entity serves each market.
Penalties for Non-Compliance
National competent authorities can investigate MiCA breaches and order conduct to stop, suspend services, prohibit offers, restrict trading, withdraw authorisation or publish the identity of the responsible person or entity.
Administrative fines can be linked to annual turnover, profit gained or loss avoided, with market abuse among the most serious categories. A firm can also lose market access, face restrictions on new clients or enter an orderly wind-down. Senior managers may face measures where personal responsibility is established.
The LEI Requirement Under MiCA: White Papers, CASPs, and the ESMA Register
MiCA imposes no standalone LEI obligation on every crypto firm, token issuer, customer or project. The requirement arises through specific authorisation, white paper, register and reporting processes.
A CASP authorisation application includes the applicant’s LEI, and the ESMA register uses LEIs to connect permissions to the correct legal entities. This is particularly relevant where several companies operate under one public brand.
For crypto-asset white papers, an eligible legal person is identified with a valid and duly renewed LEI. Only a person that is not eligible for an LEI should use another identifier required under applicable national law. Separate MiCA record-keeping rules require CASPs to identify legal-entity clients with an LEI when no alternative identifier exists at EU level.
A lapsed LEI can surface as an exception and create reporting or reconciliation problems. LEI24 is a registration agent. Companies can review how to get an LEI number through LEI24. Registration, renewal and transfer are facilitated through Nasdaq CSD SE. LEI24 does not issue LEIs.
How to Prepare for MiCA Compliance
Just follow the steps below to prepare for MiCA Compliance:
- Map the operating model. Identify every token, service, market and contracting entity, including group companies involved in technology, custody, execution, marketing, customer support or outsourcing.
- Classify each token and activity. Document the token’s rights, design and use, then match each activity and entity to a CASP application, Article 60 notification or another authorisation route.
- Review marketing and controls. Check websites, application stores, social media, affiliates, sponsorships, events and paid advertising for EU solicitation. Confirm that governance, custody, complaints, conflicts, outsourcing and market-abuse controls work in practice.
- Align filing data. Make sure white papers, corporate names, token identifiers and machine-readable fields match legal documents and public records. Where an LEI is required, confirm that the record is current using our search tool before submission.
What MiCA Means for UK Crypto Firms Now
MiCA now determines how a British crypto business can serve EU clients. Firms should map each regulated activity to the legal entity carrying it, confirm the authorisation route for any EU entity and check whether each application, white paper or record-keeping process requires a valid LEI.
Where an LEI is required, LEI24 facilitates registration and renewal through Nasdaq CSD SE. If your company already has one, you can transfer its management to LEI24 without changing the code.
Frequently Asked Questions
Does MiCA apply to NFTs?
Genuinely unique and non-fungible crypto-assets sit outside MiCA. Fractionalised interests, large collections and assets with interchangeable features can still fall within scope.
Does MiCA apply to DeFi?
Services provided in a fully decentralised manner without an intermediary generally sit outside MiCA. Projects with identifiable operators or intermediaries require a case-specific assessment.
What is the difference between an ART and an EMT?
An EMT references one official currency. An ART references another value, right or combination, which may include several currencies, commodities or crypto-assets.
What is a significant token under MiCA?
An ART or EMT becomes significant when it meets at least three statutory criteria concerning scale, use, cross-border activity, interconnectedness and wider market importance.
Is MiCA the same as MiFID II?
MiCA covers qualifying crypto-assets outside existing financial services law. MiFID II governs financial instruments, so a token’s legal classification determines which regime applies.
Do crypto firms need an LEI under MiCA?
Some firms need an LEI for specific applications, white papers or registers. MiCA creates no universal LEI requirement for every crypto business or token project.
