Earlier this year, we explored the question: Could crypto trading land you in prison?

Hungary’s new validation requirement for crypto-asset exchanges, adopted this summer, is now taking more concrete form with the publication of the Implementing Decree.

Under the new regime:

• Validation will be required whenever crypto-assets are converted, whether into other crypto or into fiat currency.
• It must be performed by a validator authorized by the Supervisory Authority for Regulated Activities (SZTFH).
• Limited exemptions apply – for example, to personal, occasional, or fully decentralized transactions.
• Two new criminal offenses remain in place for unvalidated activity.

The Implementing Decree entered into force on 30 October 2025, with the amended Crypto Markets Act applying 60 days later. Crypto service providers should now prepare to work with licensed validators and align their compliance processes accordingly.

Hungary’s new regime represents a decisive move toward a compliance-driven crypto environment, adding an additional layer of oversight beyond MiCA.
