Five reported withdrawals from Ankr’s Ethereum cross-chain bridge on Nov. 9 followed the reuse of a previously redeemed Optimism deposit, according to incident reporting.

Blockaid’s 08:42:39 UTC alert said the deposit had been used to unlock bridge-held assets; its initial estimate was about $292,000 across roughly five transactions, and it described the exploit as ongoing at that time. Onchain Lens separately reported five withdrawals and a similar initial estimate.

Crypto.news’s later transaction review valued three affected asset groups at more than $303,000: about 82.91 ankrETH (~$216,370), 515,206 ankrPOL (~$56,372), and 7.98 million ANKR (~$30,857). Two other transferred assets, aMATICb and aETHb, were unpriced, so that estimate is not a total valuation. The report said its 03:49 ET check saw no further bridge activity after the withdrawals.

## What remains unknown

Crypto.news found no confirmation that Ankr’s RPC services or users’ personal wallets were compromised. The available transaction records did not establish how the attacker obtained valid authorization or whether the weakness involved receipt validation, signing, or another component. Ankr had not responded to Crypto.news by its 10:17 UTC publication, so root cause, wider scope, and reimbursement status were not confirmed in the sources reviewed.
