Ankr's Ethereum bridge lost more than $303,000 in five exploit transactions. The contract remained unpaused after withdrawals referenced a small Optimism deposit that had already been redeemed.

The withdrawal references involved a deposit on Optimism, while the affected service was Ankr's Ethereum bridge. In the described sequence, the deposit had been redeemed before withdrawals referred to it. The deposit was described as small, and the withdrawal references came after redemption.

The five transactions together accounted for a loss above $303,000. That total is the stated amount across the exploit activity. The contract was still unpaused after the withdrawals. This status was part of the incident alongside the transaction count and aggregate loss.

The incident involved Ethereum and Optimism in the transaction description. Ankr's Ethereum bridge was the affected service, and the small deposit referenced in withdrawals was on Optimism. The loss was described across five transactions, with the total exceeding $303,000. The contract remained unpaused after that activity.
