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 — 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. In our practice, the operators who treat MiCA as a threat are the ones scrambling; the ones who treat it as a moat — one licence, whole-market access, a credibility banks recognise — are the ones winning. 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.)
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’s the whole point — one door to a market of 450 million people. 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 of orders |
| Class 2 | €125,000 | Custody, exchange, execution of orders |
| Class 3 | €150,000 | Operating a trading platform (an exchange) |
These figures are minimum initial capital in qualifying own funds, and — crucially — they’re fixed EU-wide. 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, not on capital. Our cheapest crypto licence guide works through that trade-off.
The deadlines — and why waiting is the risk
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 the lowest fees and a flat 10% tax, and Malta and Ireland the strongest reputational signal. If your users are outside the EU, MiCA may not apply at all — 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 — we structure exactly that.

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 may grant a transitional 'grandfathering' window of up to 18 months for firms that were already operating under national law, but that window is closing through 2026 — existing operators need to convert to a CASP authorisation, not wait.
How much capital does a MiCA CASP need?
It depends on the service class. Class 1 (advice, reception/transmission of orders) requires €50,000; Class 2 (custody, exchange, execution) requires €125,000; Class 3 (operating a trading platform) requires €150,000. This is minimum initial capital in qualifying own funds, held EU-wide at the same level — it does not vary by country.
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, are being converted 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.
