ZKsync has successfully recovered $5.7 million worth of stolen ZK and ETH tokens after the hacker agreed to return 90% of the funds, demonstrating a commitment to security within the cryptocurrency community.
Background and Context
The recent recovery of $5.7 million worth of stolen ZKsync recovers stolen ETH and ZK tokens is significant in the context of growing concerns over security in decentralized finance (DeFi). In recent years, hacks and exploits have become frequent in the crypto space, illustrating vulnerabilities in smart contracts and decentralized protocols. This incident, which took place on April 15, highlights the necessity for robust security measures as the industry evolves.
Historically, high-profile breaches, such as the DAO hack in 2016 and more recent attacks on various DeFi platforms, have underscored the challenge of securing digital assets. ZKsync’s successful negotiation with the hacker showcases a shift towards resolution and cooperation, rather than confrontational tactics that have often characterized similar situations. After the hacker accepted a 10% bounty and returned 90% of the stolen funds, ZKsync reflected a proactive approach to safeguarding its community and assets.
Moreover, despite the positive recovery news, the market response has been modest, as the ZK token remains nearly unchanged following the announcement. The evolution of ZKsync as a layer 2 solution using zero-knowledge rollups further emphasizes the critical balance between innovation and security in the fast-paced DeFi landscape.
ZKsync Recovers Stolen ETH and ZK Tokens
In a significant development, ZKsync has successfully recovered $5.7 million worth of stolen ZK and ETH tokens following an April 15 security incident. The hacker agreed to return 90% of the funds after accepting a 10% bounty.

The Security Incident
The breach stemmed from unauthorized access to ZKsync’s admin account, allowing the hacker to exploit the airdrop distribution contract, specifically the sweepUnclaimed()
function. This exploit enabled them to mint 111 million unclaimed ZK tokens valued at approximately $5 million at the time of the incident. Notably, the market value of the stolen tokens has since increased, with ZK and ETH rising by 16.6% and 8.8%, respectively, according to CoinGecko data.
Future Outlook
Despite the positive news regarding the recovery, the ZK token did not experience substantial growth and remains down 0.2% in the last 24 hours. ZKsync Era, an Ethereum layer 2 solution utilizing zero-knowledge rollups, currently holds nearly $59 million in total value locked and over $2 billion in real-world assets onchain, as reported by DefiLlama and RWA.xyz. This incident underscores the ongoing security challenges faced by blockchain platforms and the proactive measures necessary to protect user assets.
