In what is called the biggest heist ever, PolyNetwork, a decentralized finance (DeFi) firm working on interoperability of crypto coins was hacked and multiple cryptocurrencies were transferred out. The company claims that the value of those cryptocurrencies is estimated to be $600 million, BBC reported.
Cryptocurrencies work on blockchain technology and each coin uses its own blockchain that is unique and isolated from the rest. DeFi platforms such as PolyNetwork work to make them interoperable. Hackers exploited a vulnerability in the company’s “contract calls” and took away thousands of crypto coins. PolyNetwork revealed that $267m of Ether, $252m of Binance coins, and roughly $85 million in USDC were taken out.
Since blockchain is a public ledger, the company was quick to identify the virtual address where these currencies were deposited and alerted cryptocurrency networks to block further deposits from the addresses.
