Ankr Ethereum bridge loses over $303,000 in five-transaction exploit

Ankr's Ethereum bridge lost more than $303,000 in an exploit spread across five transactions. The attacker exploited a contract that stayed unpaused, with withdrawals referencing a small Optimism deposit that had already been redeemed. Bridge exploits erode confidence in cross-chain infrastructure and can weigh on the tokens and chains involved, though the loss is modest relative to major bridge hacks.
