zkLink Nova Bridge Loss Estimate Rises to $786,000 as Escrow Drained
Key Facts
Loss estimates for the zkLink Nova bridge exploit have risen to approximately $786,000. Blockaid reported that a large-scale withdrawal drained the protocol's Ethereum escrow account to a remaining balance of just 0.001 ETH.
The incident occurred due to a technical vulnerability in the bridge infrastructure that enabled unauthorized fund drainage, according to The Defiant. This near-total depletion of the escrow funds intensifies security concerns regarding cross-chain bridging protocols within the DeFi ecosystem.
