Why Is Zonda’s Cold Wallet Inaccessible?
Crypto exchange Zonda said a cold wallet holding more than 4,500 Bitcoin is currently inaccessible, raising concerns as the platform faces a surge in withdrawal requests. The issue centers on the wallet’s private keys, which were never transferred to current management.
Zonda CEO Przemysław Kral disclosed the wallet address in a public video, stating that the keys were supposed to be handed over by founder and former CEO Sylwester Suszek, who has been missing since March 2022.
The wallet holds 4,503 Bitcoin, valued at roughly $334 million, with its last recorded transaction dating back to November 2025. The disclosure marks the first time the exchange has publicly identified the address amid growing scrutiny.
While Kral did not confirm that the funds are permanently lost, the absence of key access leaves the assets effectively frozen, introducing operational risk for the exchange.
How Did Withdrawal Pressure Escalate?
The situation intensified following reports of a potential probe by Polish authorities and analysis from blockchain firm Recoveris, which suggested Zonda may have faced solvency issues after a sharp decline in hot wallet balances.
Kral rejected those claims, stating that the exchange remains fully solvent and holds more than 4,500 BTC. He attributed the withdrawal pressure to a sudden spike in requests triggered by negative media coverage.
According to Kral, Zonda typically processes around 100,000 withdrawal requests annually, but saw more than 25,000 requests within a short period around April 6.
“So for all those who claim that I had anything to do with Sylwester’s disappearance, this is the prime argument that I care the most about Sylwester being found,” Kral said.
Investor Takeaway
What Role Does the Missing Founder Play?
The inability to access the wallet is tied directly to the disappearance of Sylwester Suszek, who has reportedly been missing since 2022. The private keys to the cold wallet were never transferred during the leadership transition, leaving current management without control over a substantial portion of reserves.
Polish lawmaker Tomasz Mentzen said the exchange may have lost access to the wallet entirely due to the missing keys, though Zonda has not confirmed this outcome. The situation adds a layer of uncertainty that extends beyond operational issues into governance and custody practices.
Reports have also referenced alleged criminal ties among certain shareholders of the exchange, previously known as BitBay, further complicating the narrative around ownership and control.
Investor Takeaway
What Are the Broader Regulatory and Market Implications?
The incident has drawn attention from regulators and lawmakers, feeding into a broader debate around crypto oversight in Poland. Zonda had previously moved its registration to Estonia, citing regulatory uncertainty and delays in implementing the EU’s Markets in Crypto-Assets framework.
Kral said the company plans to pursue legal action over what it described as false claims and reiterated that Zonda will meet its obligations to customers despite the withdrawal surge.
