PANews reported on April 21 that ZKsync said it had sent a message to the hacker regarding last week’s security incident, offering a 10% bounty if the hacker returns 90% of the funds used in the exploit, with a refund window of 72 hours from the date the message was posted on Ethereum. After receiving all of the aforementioned ZK and ETH by the deadline, ZKsync will publicly confirm the solution. If the funds are still not returned by the deadline, the team will report the matter to law enforcement for a full criminal investigation.”
