They enable us to read and write data to the blockchain, as well as execute code. Smart contacts are written in a programming language called Solidity, which looks a lot like Javascript. It is a full blown programming language that will allow us to do many of the same types of things ...
In Solidity, it is possible to cast an address into any arbitrarily-typed contract variable, even if the contract housed at that address is not of the same type as the one being casted. Malicious actors can exploit this to conceal harmful code. Let’s see how. pragma solidity 0.8.4; imp...
