zkLink said it has confirmed an ongoing attack targeting the Arbitrator contracts tied to zkLink Nova, its aggregated Layer 3 network, on Ethereum and Optimism. The team said it is working urgently to contain the situation and prevent additional losses, with further updates to be shared with the community later.
The project also called on the party involved to stop exploiting zkLink Nova contracts across chains and return the affected funds. zkLink said it is prepared to offer a 20% white-hat bounty if the funds are returned, adding that it will not pursue the matter further after repayment.
Security firm Blockaid had earlier said the attacker injected a forged batch root on Ethereum through a public relayer, then withdrew ETH and ERC-20 tokens from zkLink Nova’s L1 custody contract. At the time, Blockaid estimated combined losses from the L1 ETH custody and ERC-20 bridge at about $786,000, and said the attack was still ongoing.
