Poland’s lower house of parliament voted 241-200 in favour of the government-backed measure, with no abstentions.
The bill will now go to the Senate, the upper house, for further debate.
The legislation designates the country’s financial regulator, the Polish Financial Supervision Authority (KNF), as the body overseeing the crypto market.
The measure is intended to implement the European Union’s Markets in Crypto-Assets (MiCA) regulation, which aims to standardise rules across the bloc, officials said.
Finance and Economy Minister Andrzej Domański said the bill would provide investors in crypto assets with protections comparable to those in other financial markets.
"In this chamber, we must always stand on the side of citizens, not on the side of fraudsters and criminals; on the side of savers, not those who want to rob them,” he told lawmakers ahead of the vote.
The bill includes a provision, proposed by the president’s office, requiring the KNF, in cooperation with the finance ministry, to publish annual reports on the functioning of the crypto market.
Other proposals from the president’s office—including additional judicial oversight of the KNF and limits on account freezes—were rejected.
Under the new rules, the KNF would be able to block bank accounts or crypto wallets and suspend transactions for up to 96 hours, with possible extensions of up to six months.
It would also have the authority to impose financial penalties on issuers, service providers and intermediaries operating in the crypto sector.
The regulator would be allowed to maintain a register of fraudulent websites linked to crypto activity and impose criminal liability for offenses such as issuing tokens or providing services without proper authorization.
The law also sets caps on supervisory fees: up to 0.5 percent for token issuers and 0.4 percent for crypto service providers.
Nawrocki had vetoed earlier versions of the bill, arguing they were overly restrictive and could drive Polish crypto firms abroad.
The KNF warned in February that without clear designation of a national supervisory authority, Polish companies could lose the ability to operate in the sector, leaving only foreign-licenced firms able to offer services in the country.
Under EU rules, entities can continue providing crypto services without a licence until July 1, Polish state news agency PAP reported.
