Why Zonda’s Cold Wallet Disclosure Raised Market Concerns
On April 16, Zonda CEO Przemysław Kral released a video statement revealing a cold wallet holding approximately 4,503 BTC, worth around $334 million. The wallet’s last recorded on-chain activity dates back to November 2025, immediately triggering questions about custody and ownership.
Missing Private Key Handover Becomes a Critical Issue
Kral stated that the private key to the cold wallet was never properly transferred during company leadership transition. The original responsibility belonged to Zonda founder and former CEO Sylwester Suszek, who has been missing since March 2022. This unresolved custody gap has become the central concern surrounding asset control.
Solvency Concerns and Regulatory Scrutiny
Zonda is now facing increasing scrutiny from both media and regulators. Local reports suggest Polish authorities have initiated investigations, while blockchain analysts have observed a sharp decline in hot wallet balances, raising concerns about potential insolvency. Despite this, Kral insists the exchange still holds over 4,500 BTC and denies bankruptcy allegations.
Withdrawal Surge and Panic Behavior
According to Kral, Zonda typically processes around 100,000 withdrawals annually, but over 25,000 withdrawal requests were submitted within days of April 6, driven by panic following negative media coverage. The company claims it will continue to honor withdrawal obligations while pursuing legal action against false claims.
Why Cold Wallet Custody Defines Exchange Risk
This incident highlights that exchange risk is not only technical but also structural. Even if on-chain assets exist, unclear custody arrangements and missing key control can trigger solvency doubts and market instability.
