Following the drainage, the team deleted the project's official website, Twitter/X account, GitHub repositories, and all other communication channels. Blockchain security firm PeckShield was among the first to report the incident. MistTrack subsequently identified that 600 ETH (approximately $1.1 million at the time) from the suspected rug pull was deposited into the Tornado Cash cryptocurrency mixer to obscure the trail. No funds have been publicly reported as recovered, and no arrests or identifications of the perpetrators have been confirmed as of the time of this investigation.","heading":"Exit Scam and Fund Drainage","severity":"critical","sources":[{"credibility":2,"name":"crypto.news: zkSync Era's Kannagi Finance rug pulls and steal $2.13m","type":"news_article","url":"https://crypto.news/zksync-eras-kannagi-finance-rug-pulls-and-steal-2-13m/"},{"credibility":2,"name":"Web3 Is Going Great: Kannagi Finance rug pulls for over $2 million","type":"news_article","url":"https://www.web3isgoinggreat.com/?id=kannagi-finance-rug-pull"},{"credibility":2,"name":"Rekt News: Kannagi Finance","type":"news_article","url":"https://rekt.news/kannagi-finance-rekt"},{"credibility":2,"name":"Kannagi Finance's $2 Million User Losses Is Being Shifted To Tornado Cash (Coincu)","type":"news_article","url":"https://coincu.com/207129-kannagi-finances-2-million-user-losses/"}]},{"content":"The Kannagi Finance smart contract architecture contained documented centralization risks that enabled the exit scam. The SourceHat (formerly Solidity Finance) audit of the ERC-4626 Vault contract noted that the MainChef address could initiate withdrawals on behalf of any user by specifying the user's address and an amount to withdraw. Additionally, the owner retained the ability to set the Strategy address and the MainChef address to any address at any time, and could upgrade the contract at any time. The audit flagged these as centralized aspects but issued an overall PASS rating with the notation 'No external vulnerabilities identified,' language that critics argue obscured the severity of the internal control risks. The deployed contract code was also unverified on-chain at the time of the rug pull, which prevented independent review and may indicate that malicious functionality was added after the audit was completed.","heading":"Smart Contract Mechanics and Exploit Vector","severity":"critical","sources":[{"credibility":2,"name":"SourceHat: Kannagi Finance Smart Contract Audit","type":"other","url":"https://sourcehat.com/audits/KannagiFinance/"},{"credibility":2,"name":"Halborn: Explained: The Kannagi Finance Rug Pull (July 2023)","type":"research","url":"https://www.halborn.com/blog/post/explained-the-kannagi-finance-rug-pull-july-2023"},{"credibility":2,"name":"Rekt News: Kannagi Finance","type":"news_article","url":"https://rekt.news/kannagi-finance-rekt"}]},{"content":"Kannagi Finance was audited by two firms prior to the rug pull. SolidProof, a German blockchain security firm, audited the ERC-20 token contract on June 6, 2023, but explicitly did not audit the Vault contracts that were the vehicle for the theft. SourceHat audited the ERC-4626 Vault contract and identified centralization risks but issued a passing grade. After the incident, SolidProof issued a public statement clarifying the scope limitation of its audit and announced a collaboration with Kyber Network to form a task force to investigate the incident. The dual-audit arrangement created a gap: SolidProof's scope excluded the vault; SourceHat's audit of the vault downplayed the centralization risks that directly enabled the drain. The Halborn security firm, analyzing the incident post-hoc, criticized the broader pattern of audit reports using careful wording to pass projects despite significant centralized control risks.","heading":"Audit History and Due Diligence Failures","severity":"high","sources":[{"credibility":2,"name":"Halborn: Explained: The Kannagi Finance Rug Pull (July 2023)","type":"research","url":"https://www.halborn.com/blog/post/explained-the-kannagi-finance-rug-pull-july-2023"},{"credibility":2,"name":"SourceHat: Kannagi Finance Smart Contract Audit","type":"other","url":"https://sourcehat.com/audits/KannagiFinance/"},{"credibility":2,"name":"ChainCatcher: SolidProof partners with Kyber Network to investigate Kannagi Finance","type":"news_article","url":"https://www.chaincatcher.com/en/article/2098171"},{"credibility":3,"name":"SolidProof statement on X","type":"other","url":"https://x.com/SolidProof_io/status/1685236707786969088"}]},{"content":"The Kannagi Finance team operated entirely anonymously. Rekt News noted that the project's operators used NFT profile pictures and Discord handles containing Chinese characters, but no real-world identities were ever disclosed or verified. Beyond team anonymity, several other warning signs were present before the rug pull. The deployed smart contract code was unverified on-chain, preventing independent review. The protocol had been live for fewer than two months before the drain. SyncSwap, the leading decentralized exchange on zkSync Era, had endorsed the project through a giveaway tweet that was subsequently deleted after the rug pull occurred. The combination of anonymous operators, unverified contracts, and the short operational timeline prior to the incident are now cited as textbook pre-rug indicators.","heading":"Anonymous Team and Pre-Incident Warning Signs","severity":"high","sources":[{"credibility":2,"name":"Rekt News: Kannagi Finance","type":"news_article","url":"https://rekt.news/kannagi-finance-rekt"},{"credibility":2,"name":"Halborn: Explained: The Kannagi Finance Rug Pull (July 2023)","type":"research","url":"https://www.halborn.com/blog/post/explained-the-kannagi-finance-rug-pull-july-2023"},{"credibility":2,"name":"BeInCrypto: A Rocky Week for zkSync Era: EraLend Security Breach and Kannagi Finance Rug Pull","type":"news_article","url":"https://beincrypto.com/kannagi-finance-zksync-era-rug-pull/"}]},{"content":"The Kannagi Finance rug pull is widely cited as the first major rug pull on the zkSync Era network. It occurred within days of a separate $3.4 million exploit of EraLend, another zkSync Era protocol, on July 25, 2023, compressing two major security incidents into roughly one week on the nascent network. The back-to-back incidents triggered significant TVL withdrawals from the zkSync Era ecosystem and attracted negative attention at a time when the network was seeking to grow its DeFi footprint. The incidents collectively drew scrutiny to due diligence standards on Layer 2 networks and to the role ecosystem-leading protocols play when endorsing unvetted projects.","heading":"Impact on zkSync Era Ecosystem","severity":"medium","sources":[{"credibility":2,"name":"BeInCrypto: A Rocky Week for zkSync Era: EraLend Security Breach and Kannagi Finance Rug Pull","type":"news_article","url":"https://beincrypto.com/kannagi-finance-zksync-era-rug-pull/"},{"credibility":2,"name":"Bitcoinist: zkSync-Native DeFi Aggregator Kannagi Finance Rug Pulls $2 Million","type":"news_article","url":"https://bitcoinist.com/defi-aggregator-rug-pulls-2-million/"},{"credibility":2,"name":"CoinUnited: Kannagi Finance Rug Pull: $2.13M Lost in Latest zkSync Era Network Incident","type":"news_article","url":"https://coinunited.io/news/en/2023-07-30/crypto/cunews-kannagi-finance-rug-pull-2-13m-loss-adds-to-zksync-era-s-troubles"}]},{"content":"No funds have been publicly reported as recovered as of the time of this investigation.
