MiCA, the Markets in Crypto-Assets Regulation (Regulation (EU) 2023/1114), is the European Union law that creates a single rulebook for crypto-assets not already covered by existing financial legislation. It regulates public offers of crypto-assets, stablecoin issuers and crypto-asset service providers (CASPs), and it applies directly in every member state without national transposition.
In crypto & blockchain, MiCA is the first comprehensive regime of its kind in a major economy. It replaced a patchwork of national registration schemes with EU-wide authorization and passporting, and it sits within a wider set of crypto security rules that also includes anti-money-laundering law and the travel rule.
What MiCA covers and what it excludes
MiCA applies to crypto-assets that are not financial instruments, deposits or other products already regulated elsewhere. Tokens that qualify as transferable securities remain under MiFID II and the Prospectus Regulation, which makes classification the first legal question for any token.
The regulation divides covered crypto-assets into three categories, each with different obligations.
| Category | Definition in brief | Main obligations |
|---|---|---|
| E-money token (EMT) | Stable value referencing one official currency | Credit institution or e-money license, redemption at par |
| Asset-referenced token (ART) | Stable value referencing other assets or a basket | Authorization, reserve, governance rules |
| Other crypto-assets | Everything else in scope, including utility tokens | White paper, marketing and conduct rules |
Several things fall outside MiCA: unique, non-fungible tokens such as most NFTs, crypto-asset services provided in a fully decentralized manner without an intermediary, and central bank digital currencies. The NFT exclusion is narrow, because large series of fractionalized or interchangeable tokens may still count as fungible.
Issuers of other crypto-assets must publish a crypto-asset white paper before a public offer or admission to trading. The document describes the issuer, the project, the rights attached to the token, the underlying technology and the main risks, and it must be notified to the competent authority, although it is not approved in advance. The issuer is liable for misleading information in it, and retail buyers generally receive a withdrawal right within a fixed period after purchase. Marketing communications must be fair, clear and consistent with the white paper.
Rules for stablecoin issuers
MiCA is strictest for stablecoins. An e-money token may only be issued by a credit institution or an electronic money institution, holders have a right of redemption at par at any time, and the issuer may not pay interest to holders. Reserve funds must be held largely as deposits with banks and in highly liquid instruments.
Asset-referenced tokens require authorization from a national competent authority, a reserve of assets that is legally segregated and regularly audited, and recovery and redemption plans. Tokens that exceed thresholds for holders, market value or transaction volume can be classified as significant, which moves supervision to the European Banking Authority and raises capital and liquidity requirements.
The regulation also caps the use of ARTs and non-euro EMTs as a means of exchange within a single currency area. When daily payment transactions exceed set limits, the issuer must stop further issuance, a rule designed to protect monetary sovereignty.
Crypto-asset service providers and their duties
Any firm offering regulated crypto services in the EU needs CASP authorization from one national authority, after which it can passport services across the union. The regulated services resemble those of traditional investment firms.
| Service | Example | Notable duty |
|---|---|---|
| Custody and administration | Holding client keys or wallets | Segregation of client assets |
| Operating a trading platform | Centralized crypto exchange | Fair and transparent operating rules |
| Exchange for funds or crypto | Broker converting euros to tokens | Published pricing policy |
| Execution and reception of orders | Routing client orders to venues | Best execution |
| Advice and portfolio management | Recommendations, managed accounts | Suitability assessment |
| Transfer services | Moving crypto on behalf of clients | Clear terms and liability |
Every CASP must meet minimum capital requirements of 50,000, 125,000 or 150,000 euros depending on its services, maintain fit and proper management, handle complaints, manage conflicts of interest and keep robust ICT security. Market abuse rules prohibit insider dealing and market manipulation in crypto-assets traded on platforms.
Timeline and transitional arrangements
MiCA entered into force in June 2023 and applied in two stages. The table below shows the key dates and their effect.
| Date | Milestone | Effect |
|---|---|---|
| June 2023 | Entry into force | Preparation by authorities and firms |
| 30 June 2024 | Stablecoin titles apply | ART and EMT rules enforceable |
| 30 December 2024 | Full application | CASP and white paper rules apply |
| Up to 1 July 2026 | End of maximum transition | Legacy national registrations expire |
Member states could grant existing providers a transitional period of up to 18 months, and many chose shorter periods. After the transition, only authorized CASPs may serve EU clients, which led several exchanges to delist non-compliant stablecoins for European users.
How MiCA relates to other crypto rules
MiCA does not stand alone. The Transfer of Funds Regulation applies the travel rule to crypto transfers, requiring CASPs to send originator and beneficiary data with every transfer regardless of amount. Anti-money-laundering law requires KYC and transaction monitoring, and DORA sets ICT resilience requirements for CASPs.
- MiCA governs issuance, stablecoins and service providers.
- Transfer of Funds Regulation carries the travel rule for crypto.
- The AML framework sets customer due diligence and reporting.
- DORA sets operational resilience and incident reporting.
- Tax rules such as DAC8 require CASPs to report client transactions.
A common misconception is that MiCA makes crypto-assets safe. It reduces operational and conduct risk at regulated intermediaries, but it does not protect investors from price falls, and it does not regulate truly decentralized protocols.
In simple terms
MiCA is the European Union rulebook for crypto. It tells companies that sell, store or trade crypto what licenses they need and how they must treat customers. One license now works in every EU country, instead of a different set of rules in each one.
It is especially strict about stablecoins, the tokens meant to stay worth one euro or one dollar. Issuers must hold real reserves and pay customers back on request. MiCA does not stop prices from falling, but it makes the companies in the middle more accountable.
A practical example
A crypto broker based in one EU member state previously operated under a national registration. To keep serving customers across Europe after the transition period, it applies for CASP authorization for custody, exchange of crypto for funds and order execution.
The application requires a business plan, proof of 125,000 euros in own funds, policies for safeguarding client assets, conflict management, complaint handling and ICT security. The broker also reviews its token list and removes a dollar stablecoin whose issuer lacks an EU e-money license, replacing it with MiCA-compliant e-money tokens.
After authorization, the broker notifies its home authority that it will serve clients in other member states. A single license now covers the whole union, and the broker can expand without separate national approvals.
