Welcome to our solidity lesson. You will learn how to create smart contracts with Solidity. Smart contracts are programs that run on blockchain.

We will cover the basics of our development environment, contract deployment, addresses, and testing. Then we will build a smart contract called Proposal Contract. You will also do some tasks to modify the code and practice your skills.

This lesson is easy to follow and we suggest you to code along with us. Feel free to copy, try, and change the code. In the Proposal Contract, we will use some key concepts like modifiers, structs, mappings, etc. These are very important for Solidity and you will need them for your own contracts. Let’s begin our lesson by learning about our development environment.
