What Is MiCA?
The EU Markets in Crypto-Assets Regulation defines crypto-asset categories, issuer obligations, CASP authorisation, and cross-border rights.
By Anton Titov, Founder · Plexo Institute
MiCA distinguishes EMT from ART, sets issuer and CASP rules, and creates EU wide rights that depend on the asset and service category.
Reading Guide
Four moves that explain how MiCA structures crypto-asset activity in the EU.
An EMT is a token that purports to maintain value by referencing one official currency. An ART is a token that is not an EMT and purports to maintain value by referencing another value, right, or combination of them. The legal category follows the token’s facts, not a marketing label.
MiCA lists crypto-asset services including custody, trading-platform operation, exchange, execution, placing, order reception and transmission, advice, portfolio management, and transfer. A provider’s permitted cross-border activity follows the Regulation’s authorisation or notification route.
MiCA provides statutory criteria for significant ARTs and EMTs. Where a token is classified as significant, the EBA takes the supervisory responsibilities specified in the Regulation, working with relevant national authorities and, where applicable, the ECB.
Whether a token may be offered, admitted to trading, or supported by a particular provider depends on its legal category, issuer status, transition rules, and the provider’s own obligations. Exchange treatment is product-specific and time-bound.
What MiCA Regulates
Crypto-assets and services not already covered by other Union financial-services legislation.
MiCA starts by sorting assets and services; the stablecoin-specific path sits inside that broader perimeter.
Authorization Turns Taxonomy Into Market Access
MiCA converts asset classification and service authorization into a practical EU distribution filter.
Classify asset
EMT, ART, or other crypto-asset
The category sets the stablecoin perimeter and issuer duties.
Issuer duties
Reserve, redemption, disclosure
Stablecoin issuers must prove backing, governance, and holder rights.
CASP gate
Services need authorization
Custody, exchange, transfer, advice, and venues pass through licensing.
Market access
Passporting scales compliant firms
Authorized firms can serve the bloc while supervision shapes execution.
E-Money Tokens (EMT): crypto-assets referencing one official currency. Asset-Referenced Tokens (ART): crypto-assets other than EMTs that reference another value, right, or combination of them; that can include one or more official currencies. Other crypto-assets: the remaining in-scope crypto-assets, which follow a different offer and disclosure regime. Financial instruments, deposits and several other products remain outside MiCA’s scope.
Crypto-Asset Service Providers can cover custody, trading platforms, exchange, execution, placing, order reception and transmission, advice, portfolio management, and transfer services. An authorised CASP may provide authorised services across the Union through the rights and notification process in MiCA; certain already-regulated financial entities use the notification path in Article 60.
ART vs EMT
The legal split is defined by the reference asset, the issuer, and the applicable title of MiCA.
For a proposed token, the starting question is whether it references one official currency or something else. The answer affects the issuer path, token obligations, and supervisory framework.
| Property | EMT | ART |
|---|---|---|
Reference | One official currency | Another value, right, or combination; not an EMT |
Issuer route | Credit institution or electronic money institution, subject to MiCA requirements | EU-established issuer authorised under MiCA, or a qualifying credit institution, subject to stated exceptions |
Holder right | Issued at par on receipt of funds and redeemable at par on request | Rights and redemption conditions follow the ART title and token documentation |
Interest | Issuer and CASP interest is prohibited under Article 50 | Issuers and CASPs must not grant interest under Article 40 |
Significance | EBA supervision is limited to requirements stated for significant EMTs | EBA supervises significant ART issuers under the Regulation |
Issuer Requirements
Issuer obligations depend on token category, issuer status, and the applicable MiCA title.
The applicable obligations differ between EMTs and ARTs and can differ again for an issuer that is already a credit institution or electronic money institution.
EMTs: issue at par on receipt of funds and redeem at par on request
ARTs: maintain and manage the reserve of assets under the ART title
Token documentation and disclosures must meet the requirements for the relevant category
Governance, complaints, continuity, ICT, and outsourcing duties apply where the relevant MiCA title requires them
MiCA sets legal criteria and a process for identifying significant ARTs and EMTs. The result is not a simple market-cap label: the applicable EBA role, national authority role, and issuer obligations depend on the token category and the relevant articles.
CASP Licensing
Authorisation examines the provider, its permitted services, and its EU operating presence.
MiCA requires an applicant to meet the statutory authorisation conditions. The precise process, evidence, timing, and transitional route depend on the Member State, applicant, services, and applicable technical standards.
A CASP applicant is authorised by the competent authority of its home Member State under MiCA’s statutory process. An authorised CASP then uses the cross-border notification process for the services and Member States it intends to cover. Do not treat a generic elapsed-time estimate as a legal entitlement or planning guarantee.
The Regulation contains transitional measures, but Member States could shorten or decline the general CASP transition. An operator must check the relevant national regime and its own authorisation status rather than infer availability from the general rule.
Passporting
EU-wide rights depend on the relevant authorisation or notification path.
An authorised CASP may provide its authorised crypto-asset services across the Union through MiCA’s notification process. ART authorisation is also valid across the Union under Article 16. EMT issuance and services follow their own provisions and issuer status. Cross-border rights do not remove ongoing obligations or the competent authority’s enforcement powers.
Enforcement Timeline
The Regulation applied in phases, with category-specific transition rules.
The relevant question is not simply whether MiCA exists: it is which title applies to the asset or service, whether a transition applies, and what the relevant operator is authorised or permitted to do.
| Date | Provisions |
|---|---|
30 June 2024 | EMT and ART rules in force |
30 December 2024 | CASP rules and consumer-protection provisions in force |
2025–1 July 2026 | CASP transition could apply to qualifying legacy providers, unless a Member State shortened or declined it; it ended earlier if authorisation was granted or refused |
After the relevant transition | An operator’s ability to provide a service depends on its applicable authorisation, notification, exemption, and enforcement status |
A listing, restriction, or delisting can be an operational signal, but it does not itself establish a universal legal conclusion. Before relying on an exchange’s treatment of any named token, verify the date, service, jurisdiction, issuer status, and the exchange’s own notice.
What MiCA Does Not Cover
Comprehensive is not exhaustive.
MiCA has statutory exclusions and boundaries; those boundaries are fact-specific and do not automatically decide the treatment of a product or service.
MiCA does not apply to crypto-asset services provided in a fully decentralised manner without an intermediary. Whether a concrete arrangement meets that boundary requires a facts-and-law analysis.
Unique and non-fungible crypto-assets can fall outside MiCA, but the Regulation also addresses series and collections. A token labelled “NFT” is not by itself a complete perimeter analysis.
Tokenized funds, security tokens, and crypto-linked investment products fall under securities and fund regimes such as MiFID II, AIFMD, or UCITS.
Counter-Arguments & Limitations
Classification, supervision, and transition status still require case-specific analysis.
MiCA harmonises important rules, but individual business models still require a fresh analysis of classification, supervision, and the relevant transition status.
MiCA gives defined cross-border rights, but Member States retain competent authorities and may apply their statutory enforcement powers. A passport is not a waiver of the issuer’s or provider’s ongoing obligations.
MiCA sets conditions for offers, admission to trading, and services in the Union. Whether a particular issuer or token can meet them is a category- and facts-specific question; do not infer that answer from an issuer’s nationality alone.
