Greece has started approving crypto-asset service provider (CASP) authorizations under the European Union's Markets in Crypto-Assets Regulation (MiCA), marking the country's transition into the fully operational phase of the bloc's unified crypto rulebook.

The approvals, granted under the Hellenic Capital Market Commission (HCMC), Greece's designated competent authority for crypto-asset services, move Greek-registered crypto firms from the MiCA transition period toward full authorization. The development signals that the licensing pipeline Brussels designed for the EU's single market for crypto assets is now functioning in one of the bloc's smaller but active jurisdictions.

MiCA entered into force in June 2023 and its provisions for crypto-asset service providers became applicable on December 30, 2024. Since that date, firms providing crypto services in the EU must either hold a full MiCA CASP license or operate under a national grandfathering regime while their application is pending. Each member state sets the length of its own transitional window, within the limits set by the regulation, and incumbent firms that fail to secure authorization before that window closes must cease activity.

For Greece, the first CASP entries under the framework represent a structural shift. Firms previously regulated under the national regime — or operating in a gray zone before MiCA — now face a single authorization standard aligned across all 27 EU member states. A CASP licensed in Greece can passport its services across the EU, a mechanism modeled on the passporting rights long available to investment firms under MiFID II. That removes the need for firm-by-firm national registrations in each market where they take on clients, consolidating compliance costs for operators that previously ran parallel legal entities in multiple jurisdictions.

The operational consequences are concrete. Authorized firms must meet MiCA's prudential requirements, including minimum capital thresholds scaled to the services they provide, custody obligations for client crypto-assets, conflicts-of-interest rules, and white-paper disclosure duties for any crypto-assets they offer. Stablecoin provisions under the regulation — covering both e-money tokens and asset-referenced tokens — impose reserve, redemption and issuance rules that fall to issuers rather than service providers, but CASPs must verify that any tokens they list comply with those requirements.

For the HCMC, the authorizations broaden its supervisory perimeter from traditional securities markets into crypto-asset services, adding on-chain supervision, complaints handling and market-abuse monitoring to its remit. The European Securities and Markets Authority (ESMA) and the European Banking Authority (EBA) coordinate the framework at the EU level, with ESMA maintaining a central register of authorized CASPs across member states.

The Greek entries also matter competitively. Several EU member states — including France, the Netherlands and Italy — moved early to process MiCA applications and large exchanges have concentrated their European licenses in a handful of jurisdictions. Greece, which built a substantial domestically regulated crypto sector before MiCA, now has a route to retain those firms under the new regime rather than lose them to faster-moving regulators.

The stakes extend beyond national boundaries. Firms that obtain a Greek CASP license gain a compliance base for the entire EU single market, which remains one of the largest pools of retail and institutional crypto demand under a single regulatory framework globally. Conversely, firms that miss the transition deadline face forced market exit, a consequence several operators in other EU states have already encountered as regulators enforce the cutoff.

The next checkpoint for Greek-licensed firms is the close of the national transitional period, after which operating without a full MiCA authorization becomes an enforcement matter rather than a licensing formality. Market participants will be watching whether the HCMC's approval pace keeps pace with its applicant pipeline as that window narrows.
