Stablecoins are the part of MiCA that arrived first and bites hardest. While most crypto-asset rules began to apply at the end of 2024, the obligations for asset-referenced tokens (ARTs) and e-money tokens (EMTs) have been in force since 30 June 2024. If your token holds its value against a currency or a basket of assets, and you issue, offer, or distribute it in the EU, you are already inside a supervised regime. This is a practical map of what issuers and distributors must have in place.
Two token types, two very different regimes
MiCA does not have a single "stablecoin" category. It splits them, and the split drives almost everything that follows.
- An e-money token (EMT) references the value of a single official currency, for example a token pegged one-to-one to the euro or the US dollar. It is treated as electronic money.
- An asset-referenced token (ART) references any other value or right, or a combination: several currencies, one or more commodities, other crypto-assets, or a basket. Anything that stabilises value but is not a single-currency EMT tends to fall here.
The label matters because it decides who is allowed to issue and under which rulebook. Get the classification wrong and every downstream control is built on the wrong foundation.
Who is allowed to issue
Only certain entities may issue these tokens to the public in the EU.
- EMT issuers must be authorised as a credit institution or as an electronic money institution (EMI) under the e-money framework. There is no separate MiCA licence to invent: you use the banking or EMI channel and notify a crypto-asset white paper.
- ART issuers must be a legal entity established in the EU and hold a specific MiCA authorisation from their national competent authority, unless they are already a credit institution meeting adapted conditions.
Distributors and trading platforms are not off the hook. Offering or admitting to trading an ART or EMT that has no compliant issuer, or no published white paper, is itself a breach. Practically, a venue must confirm the token's status before listing.
The core obligations issuers must build
Whatever the type, the substance of MiCA for stablecoins clusters around a handful of hard requirements.
- White paper. A crypto-asset white paper must be drawn up, notified to the competent authority, and published. For ARTs the white paper needs prior approval as part of authorisation.
- Redemption at par, at any time. Holders have a legal claim against the issuer and can redeem at face value. For EMTs this is redemption at par value on demand; for ARTs the redemption right and its conditions must be spelled out.
- No interest. Neither ART nor EMT holders may be paid interest linked to how long they hold the token. This closes the door on marketing a "yield" on the coin itself.
- Reserve of assets. ARTs must be fully backed by a segregated reserve of assets that is prudently managed, custodied, and largely held in highly liquid, low-risk instruments. EMTs must safeguard the funds received against the tokens issued, in line with e-money safeguarding rules.
- Own funds, governance, and risk management. Issuers face minimum own funds requirements, fit-and-proper management, conflict-of-interest rules, and documented policies for liquidity, custody, and complaints handling.
The "significant" tier
MiCA adds a heavier regime for tokens that reach scale. A token can be classified as significant when it meets several of the statutory criteria, for example more than 10 million holders, a reserve or issuance value above EUR 5 billion, or more than 2.5 million transactions and above EUR 500 million in value per day. Significant ARTs and EMTs move under direct EBA supervision and face tighter liquidity, own funds, and interoperability expectations.
There is also a usage brake. Where an ART or an EMT denominated in a non-EU currency is used widely as a means of exchange, MiCA caps activity: once it passes roughly 1 million transactions and EUR 200 million per day within the euro area, the issuer must stop issuing and present a plan to bring usage back down. This is the provision designed to keep a foreign-currency stablecoin from quietly becoming a parallel payment rail.
What this means operationally
For compliance teams the work is less about the peg and more about evidence.
- Classify every token you touch as EMT, ART, or out of scope, and document the reasoning.
- Check the issuer and the white paper before offering or listing, and keep that check refreshed.
- Monitor on-chain reality against the paper: reserve movements, redemption behaviour, and transaction volumes that could trip significance or usage thresholds.
That last point is where blockchain surveillance earns its place. Seqlense Monitoring watches token addresses on-chain, scores risk, and raises alerts, which is useful when you need to see redemption flows or volume trends before they become a supervisory conversation. Alongside it, Seqlense Doc tracks ART and EMT guidance from source:EBA and source:ESMA (filter by doctype:guidance or doctype:qa) so the rulebook you rely on stays current as the technical standards keep landing.
