An Arbitrum user reported the unauthorized transfer of 145,965.658533 USDC from their address to an external wallet, triggered by transaction 0xb611485b646d1c0b9c30d5266d724334c2479b10d235c459e3e6bc48828058a6. The recipient has posted an on-chain message demanding return of the funds to a newly specified address and stated the incident has been escalated to Hyperliquid, Circle, and blockchain security personnel.
The message indicates the user is pursuing recovery through multiple channels, including freeze and preservation requests directed at exchanges, bridges, and law enforcement. The sender also left open the possibility of a white-hat explanation, offering to negotiate a bounty contingent on full restitution of the stolen amount and explicitly refusing advance payments or disclosure of sensitive account information.
It remains unclear whether the transfer resulted from a compromised private key, a smart contract vulnerability, or another attack vector. No confirmation has been provided that any of the contacted entities have acted on the recovery request or that the funds remain traceable on-chain.
