Summary

In this chapter, we looked at defining and creating a Solidity contract. We looked at creating custom modifiers for the functions, understood the different types of functions you can define inside a contract to architect your contract behavior, learned how to create and emit events for logging purposes, and dug deeper into Solidity inheritance by creating interfaces and abstract contracts. We also learned how to write custom user-defined libraries and use them in our contracts. 

In terms of the Solidity language, we have covered all the topics that you are required to know about in order to write a basic Solidity contract. These topics cover almost 99% of the language's features, although there are ways to write assembly language blocks in Solidity as well. However, this is an advanced topic that you should take a look at in your own time. Assembly language usage...
