This chapter started with the introduction of development tools for Ethereum, such as Ganache CLI. The installation of Node.js was also introduced, as most of the tools are JavaScript- and Node.js-based. Then we discussed some frameworks such as Truffle, along with local blockchain solutions for development and testing, such as Ganache, and Drizzle. We also introduced Solidity in this chapter and explored different concepts, such as value types, reference types, functions, and error handling concepts. We also learned how to write contracts using Solidity.

In the next chapter, we will explore the topic of Web3, a JavaScript API that is used to communicate with the Ethereum blockchain.
