According to ChainCatcher, regarding the security vulnerability report dispute between Kraken and CertiK, Meir Dolev, CTO of security company Cyvers, cited the content previously shared by security researcher @tayvano on the social platform to question the June 5th time that Certik stated the vulnerability was discovered.

The 0x1d…7ac9 address created the contract 0x45…CeA9 on the Base network on May 24 and conducted related activities, and the Certik test address also used the same signature hash as the unknown address. It is suspected that the contract (0x45…CeA9) deployed on Base is also doing the same test on OKX and Coinbase to determine whether these two exchanges have the same vulnerability as Kraken.
