Zonda CEO reveals 4,503 BTC cold wallet address but says keys are missing
The disclosure adds a verifiable on-chain reference point as withdrawal delays and solvency claims collide.
Zonda CEO Przemysław Kral published a Bitcoin address holding 4,503 BTC and said the funds are currently inaccessible because the private keys were never transferred during a company handover. The move lands amid delayed withdrawals, a contested solvency narrative, and unconfirmed claims of a Polish authorities probe.
Key Takeaways
- A Bitcoin address holding 4,503 BTC was publicly disclosed by Zonda’s CEO, alongside a claim that the wallet is currently inaccessible due to missing private keys.
- The balance was about $334 million at the time of publication, and the last recorded transaction on the address dates to November 2025 per Blockchain.com.
- Recoveris alleged Zonda may have been insolvent based on a sharp decline in hot-wallet balances, while CEO Przemysław Kral said the exchange remained fully solvent with more than 4,500 BTC in holdings.
- Zonda described a sudden withdrawal surge around April 6, with more than 25,000 requests in hours and days versus roughly 100,000 per year in a typical period.
Zonda Doxxes a 4,503 BTC Cold Wallet — Then Says It Can’t Access It
Zonda CEO Przemysław Kral published a Bitcoin cold-wallet address holding 4,503 BTC and said the exchange cannot currently access it because the private keys were never transferred during a company handover.
The disclosure is unusual in its specificity. It gives the market a single, verifiable on-chain artifact to anchor the debate around Zonda’s reserves and operational capacity, at a moment when customers have been reporting delayed withdrawals.
Kral tied the missing-key issue to the exchange’s founder and former CEO Sylwester Suszek, who has been missing since 2022. Kral said the keys were intended to be handed over by Suszek and denied accusations of misappropriating funds.
Withdrawal Delays Meet a Solvency Narrative: Recoveris vs. Zonda’s CEO
The wallet reveal arrives after weeks of controversy that blended operational stress with solvency speculation. Blockchain platform Recoveris published an analysis on April 6 alleging Zonda could have been insolvent, pointing to a sharp drop in the exchange’s hot-wallet balances.
Kral rejected that framing and said Zonda remained fully solvent with more than 4,500 BTC in holdings. For traders, the distinction between “holds assets” and “can deliver assets” is the whole game during a withdrawal crunch. Hot wallets are typically used to service day-to-day flows, while cold wallets are generally where reserves sit. When hot-wallet balances fall quickly, the market tends to ask whether the exchange is paying out customers, shuffling funds internally, or simply running out of accessible inventory.
Kral also framed the episode as a rapid liquidity stress test driven by demand. He said Zonda typically processes around 100,000 withdrawal requests per year, but saw more than 25,000 requests within hours and days around April 6, which he attributed to negative media coverage.
The On-Chain Detail Traders Can Verify: Last Movement in November 2025
Per Blockchain.com, the disclosed address’s last recorded transaction was in November 2025 as of publication. That timestamp matters because it sets a clean monitoring baseline. If the wallet is truly inaccessible today, continued inactivity would be consistent with that claim.
The flip side is equally important. Any new movement from that address would be an immediate, objective signal that the “inaccessible” status has changed, regardless of what is said in statements. It would not, by itself, resolve the solvency dispute, but it would change the operational picture by showing the cold balance can be mobilized.
Kral also pushed back on claims linking him to Suszek’s disappearance, saying: “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,” referring to the missing founder.
Signals to Monitor Next: Withdrawals, Wallet Flows, and Any Official Probe
The first signal is mechanical: whether withdrawals normalize after the reported surge of 25,000+ requests around April 6, and whether Zonda provides concrete updates on processing times.
Second is on-chain: any transaction from the disclosed 4,503 BTC address, which has not moved since November 2025 per Blockchain.com.
Third is the hot-wallet narrative. Further publications from Recoveris, or similar monitoring, will likely focus on whether hot-wallet balances stabilize or continue to decline, since that was the basis for the insolvency allegation.
Finally, the regulatory overhang remains unresolved. The story references local claims of a Polish authorities probe, but no official statement or filing details are provided. Any confirmed communication from authorities would shift this from market rumor to a defined legal process.
A Public Address Helps Verification, but ‘Inaccessible Keys’ Is a New Risk Variable
I like having a concrete address because it forces the debate onto verifiable ground. Before this, the market was stuck arguing from hot-wallet inferences and withdrawal anecdotes. Now there is at least one reserve-sized balance that can be monitored in real time.
The threshold that matters is accessibility, not headline reserves. If a 4,503 BTC cold wallet is real but cannot be signed, it does not function as liquidity during a withdrawal wave. If that status changes and the wallet begins to move, the setup starts to look structural rather than narrative-driven, because it would demonstrate the exchange can mobilize deep reserves to meet obligations.
