Solidity Inheritance, Modifiers and Importing of Files¶
In this Lab you will learn how Solidity Inheritance works, what's it for and how to use Modifiers.
We will create a long and spaghetti-like Smart Contract. Then we improve it step-by-step by using first a modifier, then separate logic into an external Smart Contract and then finally into an external File.
