Polish Zondacrypto exchange stops processing withdrawals amid possible insolvency

The Polish cryptocurrency exchange Zondacrypto faced complaints that withdrawals were not being processed as far back as December 2025, but the crisis seems to have escalated. CEO Przemysław Kral attempted to assuage insolvency fears by pointing to a cryptocurrency wallet containing around 4,500 BTC (~$330 million) as proof of assets, but he also admitted that the keys to the wallet were known only to the exchange's previous CEO and not transferred during the company's 2021 sale. The former CEO has been missing for four years.

Polish authorities have launched investigations into the apparent collapse. Losses have been estimated at 350 million zł (~$96 million).

Poland's Prime Minister Donald Tusk has also recently accused Zondacrypto of sponsoring conservative and right-wing politicians, including Polish President Karol Nawrocki. Nawrocki has repeatedly vetoed legislation aiming to regulate the crypto sector, describing it as overly burdensome to crypto businesses. Tusk has also alleged that Zondacrypto was funded by the Russian mafia and Russian intelligence services. These allegations are also being investigated by Polish authorities, and one report citing the country's Internal Security Agency claims that the Kremlin-linked Tambovskaya Bratva Russian mafia group took over the exchange as far back as 2018.
