MiCA Regulation Explained for Crypto Businesses (2026)
MiCA explained in plain terms for operators — what the EU crypto regulation covers, the CASP licence classes and capital, the transition deadlines.
Contents
MiCA, the Markets in Crypto-Assets Regulation (EU 2023/1114), is the EU’s single crypto framework: one CASP authorisation passports across all 27 member states, replacing the old patchwork of national regimes. For years, running a crypto business in the EU meant navigating 27 different national regimes, and a licence in Estonia meant nothing in France. MiCA ended that. It is the single most important regulatory development in crypto, and if any part of your market is in the EU, it now governs how you operate. From the applications we have handled, the operators who resisted MiCA ended up scrambling, while those who planned for it gained whole-market access from one licence and a credential banks recognise. Here’s what it actually says, and what to do about it. (The transitional window for legacy registrations has now closed; see what unlicensed EU crypto firms do now.)
- MiCA is the EU’s single crypto rulebook — one licence (the CASP) passports across all 27 member states.
- The CASP has three capital classes by service: €50k (advice), €125k (custody/exchange), €150k (trading platform).
- Stablecoin rules applied from June 2024, the full CASP regime from December 2024; national grandfathering windows have since closed.
- A CASP must be an EU-established entity with real substance — non-EU groups license an EU subsidiary.
What MiCA actually is
MiCA (the Markets in Crypto-Assets Regulation, formally EU 2023/1114) is a single, directly-applicable EU law that replaces the old patchwork of national crypto regimes with one framework. Its central instrument is the CASP (Crypto-Asset Service Provider) authorisation: get licensed in one member state and you can passport your services across all 27. That gives access to a market of 450 million people through a single authorisation. It covers exchanges, custody, brokerage, portfolio management, advice and the issuance of stablecoins, and it brings crypto firms broadly into line with the standards traditional financial institutions already meet.
The three CASP classes
MiCA sizes the capital requirement to the risk of the service you provide. There are three tiers:
| Class | Min. capital | Covers |
|---|---|---|
| Class 1 | €50,000 | Advice, reception & transmission and execution of orders, placing, transfer services, portfolio management |
| Class 2 | €125,000 | Class 1 services plus custody and exchange (crypto for funds or for other crypto) |
| Class 3 | €150,000 | Operating a trading platform (an exchange) |
These figures are the permanent minimum capital from Annex IV, and they’re fixed EU-wide. Article 67 then requires the higher of that minimum or a quarter of last year’s fixed overheads, held as own funds, an insurance policy or both. You will not find “cheaper capital” in one member state versus another, which is why, within the EU, jurisdictions compete on state fees, tax rate, review speed and banking. Our cheapest crypto licence guide works through that trade-off.
The deadlines and the transition
Stablecoin rules applied from 30 June 2024 and the full CASP regime from 30 December 2024. Member states could allow a transitional window of up to 18 months for firms already operating under national law, and those windows expired during 2026. A firm still relying on an old national registration (Estonia, Lithuania and others) needs a CASP authorisation to operate, and regulators are working through a queue, so a late start means a gap in the right to operate.
The outcome is on the public record: ESMA’s register of authorised CASPs is the scoreboard that shows which firms made the conversion and which did not.
Whatever else can be said about MiCA, it exists and it is operable, which the US alternative is not yet. Firms that deferred an EU authorisation while waiting for a comparable American framework are still waiting: the CLARITY Act, the US market-structure bill, hit the August 2026 recess without a floor vote.
What MiCA demands of a CASP
Beyond capital, a CASP authorisation carries the full weight of financial-services compliance: a robust AML/CFT framework with an appointed MLRO, fit-and-proper management, segregation and safekeeping of client assets, transparent disclosures, complaint-handling, and a DORA-compliant technology and operational-resilience programme. The application itself is substantial — a programme of operations, governance and risk policies, financial projections and proof of substance in the member state. This is a financial licence, and the file has to read like one. Our VASP, CASP & MiCA explainer breaks down the difference between the old registrations and the new authorisation.
What to actually do about MiCA
The practical decision comes down to where you license. All EU CASPs share the same capital and rulebook, so you choose on speed, cost, tax and banking. In our experience Lithuania and Estonia offer the shortest review queues and established crypto-banking relationships, Bulgaria a flat 10% tax and FSC fees below Malta’s, and Malta and Ireland a strong reputational signal. If your users are outside the EU, MiCA may not apply at all, and an offshore VASP or a VARA licence could fit better, at lower cost and speed. And if you’re a non-EU group, you serve the EU by incorporating and licensing an EU subsidiary, which is a structure we set up regularly.

Frequently asked questions
What is MiCA in simple terms?
MiCA, the Markets in Crypto-Assets Regulation (EU 2023/1114), is the EU's single rulebook for crypto. It replaces the patchwork of national regimes with one licence, the CASP (Crypto-Asset Service Provider) authorisation, that passports across all 27 member states. Get authorised in one EU country and you can serve the whole union.
When did MiCA take effect?
The rules for stablecoins (asset-referenced and e-money tokens) applied from 30 June 2024, and the full CASP regime applied from 30 December 2024. Member states could grant a transitional 'grandfathering' window of up to 18 months for firms that were already operating under national law, and those windows have now closed, so existing operators need a CASP authorisation to keep operating.
How much capital does a MiCA CASP need?
It depends on the service class. Class 1 (advice, reception/transmission and execution of orders, placing, transfer services, portfolio management) requires €50,000; Class 2 (adds custody and exchange) requires €125,000; Class 3 (operating a trading platform) requires €150,000. These are floors that do not vary by country. MiCA Article 67 requires the higher of the floor or a quarter of the previous year's fixed overheads, held as own funds, an insurance policy or both.
Does MiCA replace national crypto licences?
Yes. MiCA supersedes the old national VASP registrations inside the EU. Estonia's and Lithuania's national regimes, for example, have been folded into the CASP framework. A firm that held a national registration must now obtain a CASP authorisation to keep operating; the national permit alone is no longer sufficient.
Can a non-EU company get a MiCA licence?
Not directly — a CASP must be a legal entity established in the EU with a registered office and real substance in a member state. A non-EU group serves the EU by incorporating an EU subsidiary and licensing that entity. There is a limited 'reverse solicitation' carve-out, but it is narrow and cannot be used as a marketing strategy.
