Surely all of you heard about the famous hack that happened for the poly network (600m$) and first i thought that its the polygon network
But what happened exactly is that 3 transaction from 3 deference blokchains was made by the hacker so can someone explain to me what is the poly network exactly?
I have investigated this hack, so I will explain to you. In simple words, polynetwork is like a big bridge for different blockchain. It connects BTC, Ethereum, BSC, Heco, Neo, Ontology etc.
This hacker called a special method in the smart-contract’s bridge that added his wallet to the owner of storage, he made himself an relayer, so he got access to all assets.
