According to Techub News, in response to the security vulnerability report dispute between Kraken and CertiK, Meir Dolev, CTO of security company Cyvers, tweeted to question Certik's statement that the vulnerability was discovered on June 5: "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 this contract (0x45...CeA9) deployed on Base has also conducted the same test on OKX and Coinbase to determine whether these two exchanges have the same vulnerability as Kraken."
