Intro: Getting Started with Solidity for Blockchain Development

Welcome to this guide, where we will take a beginner-friendly approach to explore the world of Solidity – a high-level, statically-typed programming language used for building smart contracts on the Ethereum blockchain. Engage, learn, and enlighten yourself as we venture into the cryptic world of blockchain development.

1. What is Solidity?

Solidity was designed to enable writing smart contracts that run on the Ethereum Virtual Machine (EVM) — the runtime environment that executes all smart contracts on Ethereum. With Solidity, developers can create complex contracts for various use cases, including voting, crowdfunding, blind auctions, multi-signature wallets, and more.

2. Set up Solidity Development Environment

Here’s what you need to begin:

  • A text editor such as Visual Studio Code or Atom
  • Node.js and NPM (Node Package Manager)

Once you have these, you need to install Truffle, an Ethereum development environment. It’s as easy as running npm install -g truffle on your terminal.

3. Write Your First Smart Contract

A smart contract in Solidity looks similar to a class in object-oriented programming languages. It has a name, state variables that store data, and functions that define what it can do. Create a new .sol file for your contract with the contract keyword followed by its name.


Contract HelloWorld {

Adding a function to your contract is as simple as:

Contract HelloWorld {
function getMessage() public pure returns(string memory) {
return “Hello, world!”;

The function getMessage() in this example contract returns the classic “Hello, world!” message.

4. Deploy Your Smart Contract

Deployment of a smart contract on the Ethereum network involves translating your Solidity code into a format the EVM can execute. This is called compiling. With Truffle, you can compile your contracts using the command truffle compile in your terminal.

5. Interact with Your Smart Contract

Once your contract is deployed, you can interact with it using web3.js, a collection of libraries that allow you to interact with a local or remote Ethereum node using HTTP, IPC, or WebSocket.
