According to Cyvers CTO @Meir_Dv, a Certik-associated address: 0x1d…7ac9 created a contract: 0x45…CeA9 on the Base on May 24, which casts doubt on Certik’s claim that the vulnerability was discovered on June 5. The address is also testing OKX and Coinbase on May 24 to see if there is the same vulnerability as Kraken.
