+## WTF is Solidity?
 
-Solidity is the programming language for Ethereum's virtual machine (EVM), used in smart contract development. I believe that Solidity is an important skill to master in order to navigate the on-chain ecosystems and projects. Blockchain projects are mostly open sourced and once you understand its underlying source code, you are better equipped to avoid rugpull and shady projects.
