Blockchain safety agency Cyvers confirmed that the stolen funds had been initially bridged to Ethereum and funneled by the privateness protocol Railgun.
The funds had been then redirected to the unique deal with as a result of protocol’s inner insurance policies, Cyverse stated on Monday.
Following the incident, zkLend paused all withdrawals and suggested customers to carry off on depositing or repaying loans whereas they investigated the incident.
The breach has raised alarm bells within the DeFi area, because it comes as part of rising safety issues throughout the sector. Cybercriminals have already stolen over $110 million from blockchain tasks this 12 months, in keeping with DeFiLlama knowledge.
zkLend reached out to the hacker with an on-chain message providing a ten% “white hat” bounty in change for the return of the remaining funds—amounting to three,300 ETH (roughly $8.78 million).
“Upon receiving the transfer, we agree to release from any and all liability regarding the attack,” the platform knowledgeable.

"This was one of the biggest hacks on Starknet if not the biggest in recent years,” Preetam Rao, CEO and Co-founder of web security firm QuillAudits, told Decrypt. “Good to see zkLend is being transparent throughout the situation also offered a bounty to the hacker.”
The root cause of the hack doesn't seem to be in the proof system, but rather in the contract logic,” Rao said, noting his team is reviewing the incident to prevent similar issues in other protocols.
Speaking to Decrypt, Meir Dolev, Co-founder and CTO of Cyvers, noted: "This incident highlights safety dangers in DeFi lending and raises issues in regards to the security of protocols on Starknet’s zero-knowledge rollup infrastructure.”
Not like conventional coin mixers akin to Twister Money, which swimming pools and redistribute funds to obscure their origin, the zkLend hackers used Railgun which integrates privateness options instantly into DeFi functions, guaranteeing customers' anonymity whereas interacting with the blockchain.
"We are committed to full transparency and will share a comprehensive post-mortem analysis as soon as it is completed," the staff tweeted, urging customers to stay affected person as they work by the incident.
