Cyvers CTO questioned the timing of CertiK's discovery of the Kraken vulnerability, stating that CertiK allegedly conducted similar tests on OKX and Coinbase.

ChainCatcher message, regarding the dispute over the security vulnerability report between Kraken and CertiK, Meir Dolev, the Chief Technology Officer of the security company Cyvers, referenced previously shared content by security researcher @tayvano on social media to question the vulnerability discovery date stated by Certik on June 5.

The address 0x1d…7ac9 created the contract 0x45…CeA9 on the Base network on May 24 and engaged in related activities, while the Certik testing address also used the same signature hash as this unknown address. It is suspected that this contract deployed on Base (0x45…CeA9) has also conducted the same tests on OKX and Coinbase to determine if these two exchanges have the same vulnerabilities as Kraken.
