It was also discovered that the attacker used Circle’s CCTP(Cross- Chain Transfer Protocol) to move USEDC from Arbitrum to Ethereum(ETH) and later converted to DAI. This has triggered criticism among the people involved with the community and are questioning why Circle didn’t freeze the stolen USDC in time.
