Velocore, a DEX on zkSync and Linea blockchains, was hacked, losing $10M. Hackers exploited liquidity provider tokens, transferring 700+ ETH to Ethereum mainnet. Despite security audits, Velocore's vulnerability was exposed. Linea Blockchain halted block production for an hour during the breach. Velocore collaborates with CEXs to freeze stolen assets and tracks the hacker. This incident underscores ongoing security challenges in the crypto sector.
