Circle has implemented a precautionary freeze on four Ethereum Virtual Machine (EVM) addresses, as reported on October 14th. The action follows claims by ZachXBT that the funds in these addresses are linked to a theft involving Coinbase. Despite the freeze, the addresses contained Dai, not USDC, enabling the perpetrators to bypass the restriction by converting Dai to USDC. Intelligence and tracking efforts are being supported by Bitrace and MistTrack.
