Hungary repealed its separate national validation regime for crypto-asset exchange transactions on 7 August 2026. The change removes an additional Hungarian approval layer that operated alongside the EU Markets in Crypto-Assets Regulation (MiCA). It does not abolish MiCA authorisation, anti-money-laundering controls, the crypto Travel Rule, tax obligations or ordinary criminal law.
For providers, investors and internationally mobile clients, the key distinction is simple: a separate validation declaration is no longer required under the repealed Hungarian regime, but regulated crypto services still need a valid MiCA route.
Last reviewed: 17 August 2026.
Why Hungary repealed the validation regime
Hungary introduced the national validation system in 2025. Certain exchanges of crypto-assets for money or other crypto-assets were brought within a framework that required a declaration from a validator authorised and supervised by the Supervisory Authority for Regulated Activities (SZTFH).
The European Commission opened infringement procedure INFR(2025)2174 in January 2026. It said the Hungarian regime introduced an authorisation system not provided for by MiCA and had reportedly caused some crypto-asset service providers to suspend or discontinue services, harming clients and creating legal uncertainty. The Commission accepted Hungary’s objective of strengthening AML safeguards but stated that national measures must remain compatible with MiCA.
Act XXXVIII of 2026 described validation as a competition-restricting requirement that could not be maintained within the EU internal market. The repeal restores a more clearly MiCA-centred structure.
Hungary crypto regulation before and after 7 August 2026
| Regulatory issue | Before the repeal | Position from 7 August 2026 |
|---|---|---|
| Exchange validation | Certain crypto-to-funds and crypto-to-crypto transactions fell within a separate validation framework | The national validation requirement has been removed |
| Validator oversight | SZTFH licensed and supervised validation providers | SZTFH’s validation-specific mandate has been repealed |
| Validator authorisations | A dedicated Hungarian authorisation and register applied | Existing validation authorisations lost effect on 7 August 2026 |
| Pending procedures | Validation licensing and supervisory cases could be in progress | The Act requires the covered procedures to be terminated |
| Detailed licensing rules and fee | Separate rules governed applications, registration and the administrative fee | The implementing decrees were repealed on 2 August 2026 |
| Validation data | SZTFH and validators held information obtained under the validation system | The Act required specified data to be irreversibly deleted within three working days after its entry into force |
| Crypto-specific offences | Specific criminal provisions supported the validation model | The provisions tied to the repealed regime were removed; general criminal law continues |
| CASP authorisation | MiCA applied in addition to the Hungarian validation layer | A valid MiCA authorisation, notification or cross-border route remains necessary |
| Overall framework | MiCA plus a parallel national checkpoint | MiCA, Hungarian implementing law and generally applicable AML, tax and criminal rules |

What happened to validator licences and pending cases?
The main statutory repeal took effect on the eighth day after publication, which was 7 August 2026. On that date, existing authorisations for crypto-exchange validation services lost effect by operation of law.
The Act also directs SZTFH to terminate pending validation-related licensing and supervisory proceedings. A former validator cannot treat the discontinued Hungarian authorisation as a MiCA licence, convert it automatically into one or use it as a substitute for authorisation to provide regulated crypto services.
Any former validator wishing to provide exchange, custody, transfer or another regulated service must establish a separate lawful basis under MiCA for each service offered.
Which data had to be deleted?
Act XXXVIII required SZTFH and validation providers to irreversibly delete specified data in their possession concerning crypto-asset exchanges and unauthorised crypto transactions within three working days after the Act entered into force.
This targeted rule concerned data held under the former validation system; it did not require CASPs, banks, tax authorities or customers to erase every crypto record. Other retention duties may continue, so former validators needed a documented legal basis for deletion or continued storage. Investors should preserve their own transaction, banking and tax evidence.
What remains regulated under MiCA?
The repeal removes duplication; it does not create an unregulated crypto market.
Authorisation remains essential
Under Article 59 of MiCA, crypto-asset services in the EU generally may be provided only by an authorised crypto-asset service provider (CASP) or by an eligible regulated financial entity using the notification route under Article 60.
For a provider established in Hungary, the Magyar Nemzeti Bank (MNB) is responsible for authorisation. A CASP authorised in another EEA state can operate cross-border after completing the MiCA notification process. Its authorisation must cover the service offered, such as custody, trading, exchange, execution, advice or transfers.
Hungary’s former validator authorisation covered a different function and is not a MiCA passport.
The MiCA transitional period has ended
The maximum MiCA grandfathering period ended on 1 July 2026. ESMA has instructed unauthorised providers to stop onboarding and marketing, restrict activity to what is necessary for an orderly wind-down, and safeguard client interests.
Providers and customers should verify the relevant legal entity and service in the current ESMA MiCA register. A familiar brand name is not enough: authorisation belongs to a particular legal entity and specifies the services it may provide.
Operating and client-protection duties continue
Authorised CASPs remain subject to MiCA requirements covering governance, prudential safeguards, client-asset protection, complaints handling, conflicts of interest, outsourcing and orderly wind-down. Service-specific rules also apply to custody, trading platforms, exchange, execution, advice and transfers.
Removing the validation declaration does not weaken these obligations or eliminate MNB supervision.
AML, Travel Rule and sanctions controls continue
Customer due diligence, transaction monitoring, sanctions screening, suspicious-activity reporting and source-of-funds checks remain separate from the former validation process.
The EU Transfer of Funds Regulation extends originator and beneficiary information requirements—the crypto Travel Rule—to covered crypto-asset transfers. MNB’s current CASP authorisation guidance expressly addresses AML controls and the Travel Rule as part of the regulatory framework.
Tax and recordkeeping obligations continue
The repeal is not a tax amnesty. Hungarian and cross-border tax consequences depend on the taxpayer, transaction and residence position. Businesses and individuals must continue to retain appropriate records and obtain advice for their circumstances.
The removal of the crypto-specific criminal provisions also does not legalise fraud, money laundering, sanctions violations, tax offences, market abuse or other conduct prohibited by general law.
What does the change mean for crypto businesses?
It does not automatically permit a platform to launch or resume every service. The provider must still confirm:
- that the correct legal entity is authorised;
- that the authorisation covers each service offered;
- that any cross-border notification has been completed;
- that Hungarian AML, consumer and tax-facing procedures are operational;
- that client communications and terms accurately describe the regulatory position;
- that any data from the former validation system has been handled lawfully.
A provider that is not authorised under MiCA cannot rely on the repeal as permission to continue normal operations.
What does the change mean for investors?
Customers no longer need the separate transaction-level declaration required by the repealed validation framework. However, they should continue to check the status of their exchange or custodian and maintain complete evidence for significant transactions.
A practical investor file should include:
- the identity of the authorised service provider;
- account statements and transaction exports;
- wallet addresses and transaction hashes;
- evidence of how the assets were acquired;
- bank records connecting fiat transfers to the crypto activity;
- tax returns and calculations where relevant;
- a clear source-of-wealth and source-of-funds explanation.
These records can matter when opening a bank account, transferring a large amount, acquiring property, funding a company or documenting assets for an immigration application.
Practical next steps
Crypto businesses should map every activity to the relevant MiCA service, verify authorisation and cross-border status, update client materials, confirm AML and Travel Rule controls, and document the treatment of former validation data.
Investors should verify providers through official registers, preserve their records and avoid moving assets solely on the assumption that repeal of the validation regime removed all compliance risk.
For internationally mobile founders, investors and families, the regulatory status of the provider is only one part of the analysis. Banking, tax residence, wealth structuring and immigration due diligence can impose separate documentation requirements.
