11 Tools, Languages, and Frameworks for Ethereum Developers

This chapter is an introduction to the tools, languages, and frameworks used for Ethereum smart contract development. We will examine different methods of developing smart contracts for the Ethereum blockchain. We will discuss various constructs of the Solidity language in detail, which is currently the most popular development language for smart contract development on Ethereum.

In this chapter, we will cover the following topics:

Languages
Compilers
Tools and libraries
Frameworks
Contract development and deployment
The Solidity language

There are a number of tools available for Ethereum development, including clients, IDEs, and development frameworks.
