Chapter 6. Writing more complex smart contracts
This chapter covers
- Building a crowdsale management Dapp showing how to structure complex contracts
- Extending the crowdsale management Dapp through single and multiple inheritance
The purpose of the previous chapter was to give you a foundation in Solidity, so I focused mainly on the basic syntax that the language offers. In the next two chapters, I’ll introduce more advanced object-oriented (OO) features. I’ll start with inheritance in chapter 6 and follow with abstract contracts and interfaces in chapter 7. These OO features allow you to reduce code duplication and make your contracts more composable.
The contract side of real-world Dapps is generally more complex than ...
