An on-chain investigator has named French cooperative bank Crédit Mutuel Arkéa as the alleged victim in a suspected crypto theft estimated by ZachXBT at more than $133 million. The attribution is not confirmed: The Block reported that the bank had neither confirmed nor denied the incident, and that no bank or authority had verified ZachXBT’s claim.

Separate on-chain work by Bitquery traced about $108.8 million in USDC transfers from the main Ethereum wallets of Kraken, Crypto.com and OKX to 15 addresses across Nov. 1–2. Bitquery says its analysis is limited to the wallets and chain it examined, and notes that some address ownership assumptions are unconfirmed. The $133 million figure remains ZachXBT’s estimate, not a bank-confirmed loss.
