Amidst the chaos, a potential white hat hacker, known as “c0ffebabe.eth,” took action to secure some funds for safekeeping. On July 30, this hacker sent an on-chain message, urging affected protocols to get in touch to coordinate the return of funds.
Positive Developments: Recovery of Funds
To the relief of some victims, c0ffebabe.eth’s wallet successfully returned nearly 2,900 Ether (ETH) worth over $5 million to Curve through a transaction.
