What is MiCA, and how does the EU regulate crypto-assets?
Since the end of 2024 one law has set the ground rules for crypto issuers and service providers across the European Union. Here is what it covers and what changed when its transition ran out in July 2026.
Education only, not investment, tax or legal advice. Crypto-assets are high-risk — risk disclosure.
The short answer
MiCA (Markets in Crypto-Assets) is EU Regulation 2023/1114. It sets one set of rules across the EU for issuing crypto-assets, stablecoins and crypto services. Stablecoin rules applied from 30 June 2024, the rest from 30 December 2024, and the transition for existing firms ended on 1 July 2026.
Key takeaways
- MiCA is a regulation, so it applies directly in every EU member state without being rewritten into national law.
- It sorts crypto-assets into three groups: e-money tokens, asset-referenced tokens and all other crypto-assets, each with its own rules.
- Firms that exchange, hold or transfer crypto for clients need a licence as a crypto-asset service provider (CASP), which then works across the whole EU.
- As of October 2026 the grandfathering period is over: ESMA says firms serving EU clients without a MiCA licence are in breach of EU law.
What is MiCA and why does it exist?
MiCA stands for Markets in Crypto-Assets. Its formal name is Regulation (EU) 2023/1114, adopted by the European Parliament and the Council on 31 May 2023 and published in the EU's Official Journal on 9 June 20231. Before MiCA, each EU country decided for itself whether and how to supervise crypto businesses.
Because MiCA is a regulation rather than a directive, it is binding in its entirety and applies directly in all member states2. National authorities still license and supervise firms, but they all apply the same text, coordinated by the European Securities and Markets Authority (ESMA) and the European Banking Authority (EBA).
MiCA defines a crypto-asset broadly: a digital representation of value or a right that can be transferred and stored electronically using distributed ledger or similar technology4.
Which crypto-assets does MiCA cover?
MiCA splits crypto-assets into three buckets, and the rules get stricter the more a token looks like money. An e-money token (EMT) tries to keep a stable value by tracking one official currency, such as a euro stablecoin. An asset-referenced token (ART) tries to stay stable by tracking something else, or a mix of things, for example a basket of currencies or a commodity. Everything else, including bitcoin and most utility tokens, falls into a third, general category4.
How MiCA sorts crypto-assets Source: [4]
| Category | What it is | Who may offer it to the public | Example of the type |
|---|---|---|---|
| E-money token (EMT) | Stable value by reference to one official currency | A licensed bank or electronic money institution | A token pegged 1:1 to the euro |
| Asset-referenced token (ART) | Stable value by reference to other assets or a mix | An issuer authorised for ARTs, or a bank | A token tracking a basket of currencies |
| Other crypto-assets | Anything else in scope | A legal person that publishes a white paper | Bitcoin, ether, most utility tokens |
| Out of scope | Unique, non-fungible items; financial instruments; deposits; funds | Covered by other EU laws, or not at all | One-of-a-kind digital art, tokenised shares |
The exclusions matter. MiCA does not apply to crypto-assets that are unique and not fungible, such as one-off digital art, or to products already covered by other EU financial laws, including financial instruments, deposits and funds1.
When did MiCA take effect?
MiCA came in stages2. The rules for stablecoins (Titles III and IV, covering ARTs and EMTs) applied first, from 30 June 2024. Everything else, including licensing for crypto service providers, applied from 30 December 20242.
Figure · MiCA's staged start
- 31 May 2023MiCA adopted
- 9 Jun 2023Published in the EU Official Journal
- 30 Jun 2024Stablecoin rules (ART and EMT) apply
- 30 Dec 2024All other rules apply, CASP licensing opens
- 1 Jul 2026Transition ends
To avoid switching off existing businesses overnight, Article 143 let crypto firms that were already operating legally under national law before 30 December 2024 carry on until 1 July 2026, or until their MiCA application was granted or refused, whichever came first3. ESMA has confirmed that this window closed across the EU on 1 July 2026, and that in some countries it had already ended earlier11.
What does a crypto firm need to operate under MiCA?
Under Article 59, nobody may provide crypto-asset services in the EU unless they are authorised as a crypto-asset service provider (CASP) or belong to certain already-regulated categories, such as banks8. MiCA lists ten such services, from custody and running a trading platform to exchanging crypto for money or other crypto, executing orders, giving advice, managing portfolios and transferring crypto on a client's behalf4.
The licence is a passport. Once authorised in one member state, a CASP may serve clients throughout the EU, either by setting up a branch or by providing services across borders8.
- Issuers of ordinary tokens must be a legal person and draw up, notify and publish a crypto-asset white paper before offering the token to the public5.
- Small offers are exempt from the white paper duty, for example offers to fewer than 150 people per member state, or totalling no more than EUR 1,000,000 over 12 months5.
- Service providers need CASP authorisation from their home regulator before serving EU clients8.
The supervisory set-up may change. In December 2025 the European Commission proposed moving direct supervision of certain crypto-asset service providers from national authorities to ESMA; ESMA described this as a proposal that the EU's co-legislators still had to work through13.
How does MiCA treat stablecoins?
Stablecoins get the toughest treatment because they are designed to be used like money. Only a licensed credit institution or an electronic money institution may offer an e-money token to the public in the EU, and MiCA treats EMTs as electronic money in law7. Asset-referenced tokens may only be offered by an issuer authorised for that purpose and established in the EU, or by a credit institution6. E-money tokens also cannot pay interest, whether from the issuer or a crypto firm, and any reward tied to how long you hold one counts as interest14.
Figure · Two kinds of EU stablecoin
E-money token
- Tracks one official currency
- Issued by a bank or e-money institution
- Legally treated as electronic money
Asset-referenced token
- Tracks other assets or a mix
- Issued by an authorised issuer or a bank
- Separate authorisation regime
When a stablecoin grows large enough to be classed as significant, supervision moves up a level. Issuers of significant ARTs carry out their activities under the supervision of the EBA, and the EBA also supervises specific obligations for significant EMTs issued by electronic money institutions9. For the US approach to the same problem, see our explainer on the GENIUS Act, and for the basics, how stablecoins work.
What does MiCA mean for ordinary crypto users?
For users, the big change is a public list of who may serve you. ESMA publishes an interim MiCA register with files on authorised CASPs, ART and EMT issuers, published white papers and entities flagged as non-compliant, updated weekly10. In June 2026 ESMA urged clients to check whether their provider is authorised under MiCA in its register and, if not, to move their assets to an authorised provider or a wallet they control themselves12.
How to check a crypto provider under MiCA
- 1
Find the legal entity
Look in the platform's terms for the exact company name and the EU country where it is licensed.
- 2
Search ESMA's register
Check the CASP file of the interim MiCA register10 and confirm the services you use are listed.
- 3
Check the national regulator
Cross-check with the home regulator named in the register. Our guide on checking a regulated firm walks through it.
- 4
Act if it is missing
ESMA says unauthorised providers should now only let clients sell, transfer or close positions12.
Common beginner mistakes
Thinking MiCA makes crypto safe
MiCA regulates firms and disclosures. It does not stop prices falling, and a white paper is not an endorsement by any regulator.
Assuming every EU-facing app is licensed
A website in your language is not a licence. Check the register, not the marketing.
Confusing a stablecoin with a bank deposit
MiCA treats e-money tokens as electronic money, but they are not bank deposits; read how the issuer handles redemption.
Forgetting what MiCA leaves out
Unique NFTs and tokenised securities sit outside MiCA, so its protections do not automatically apply to them.
Risk warning
Regulation is not a safety net for prices
Crypto-assets can lose most or all of their value, and a licensed provider can still fail. Never put in money you cannot afford to lose, and read our risk disclosure.
Frequently asked questions
Does MiCA apply to bitcoin?
Yes, in part. Bitcoin has no issuer, so there is no white paper to file for it, but firms that exchange, hold or transfer bitcoin for EU clients need a CASP licence under MiCA.
Does MiCA apply to companies outside the EU?
It applies to anyone providing crypto-asset services in the EU. A firm based elsewhere needs MiCA authorisation, through an EU-established entity, to serve EU clients as a crypto-asset service provider8.
Is MiCA the same as the EU's crypto Travel Rule?
No. MiCA covers licensing, disclosure and conduct. Rules on sending sender and recipient information with crypto transfers come from separate anti-money-laundering law; see our Travel Rule explainer.
The bottom line
MiCA gives the EU one crypto rulebook: stablecoin issuers must be licensed money-type institutions, other token issuers must publish white papers, and anyone serving EU clients needs a CASP licence. As of October 2026 the transition is over, so the register, not the marketing, is the place to check a provider. None of this removes the price risk of crypto-assets themselves.
