MiCA (EU crypto regulation)
MiCA (Markets in Crypto-Assets) is the EU regulation on crypto-assets: one set of rules for stablecoin and token issuers and for crypto service providers across all EU countries.
How it works
MiCA was adopted in 2023 as Regulation (EU) 2023/1114. The stablecoin rules have applied since 30 June 2024, and the rest since 30 December 2024. Countries could give firms already operating under national rules a transition period, but no longer than until 1 July 2026.
The regulation splits tokens into groups: tokens tied to one official currency (e-money tokens, which covers dollar and euro stablecoins), tokens tied to a basket of assets, and other crypto-assets. Stablecoin issuers need authorisation and reserves, while other tokens generally need a published white paper.
Exchanges, custodians, brokers and exchangers in the EU are called CASPs (crypto-asset service providers) and get a licence in one EU country that works across the whole union. For you this means more rules on transparency, safekeeping of client assets and advertising, and also more checks. Fully decentralised services and most NFTs are not directly covered.
A European user wants to buy a stablecoin on a MiCA-licensed platform. If that stablecoin's issuer has no EU authorisation, the platform may restrict it for EU customers and offer a different stablecoin whose issuer is authorised.
A mistake is thinking a MiCA licence guarantees your money is safe or that you will profit. It means the company meets the requirements and is supervised, but crypto stays volatile and nobody compensates market losses. Check the service's licence in the regulator's register, and still do not keep more on one platform than you are prepared to risk.
Questions and answers
What is MiCA in simple terms?
It is the EU-wide crypto law: who can issue tokens and provide crypto services in the European Union, and on what terms.
When did MiCA come into force?
The stablecoin rules apply from 30 June 2024 and the rest from 30 December 2024. The transition period for existing firms could last no later than 1 July 2026.
Does MiCA affect users outside the EU?
It directly regulates firms serving customers in the EU. If you live outside the EU, your own country's rules apply, though large services often change terms for everyone.
