(Mastering) Solidity, the Ethereum Programming Language

A Practical Developer Guide

What you will learn

Why take this course?

This course aims to give an overview of what you need to know to program in Solidity.

The course currently consists of three parts.

‘;
}});

In the first part, I explain some basic blockchain concepts.

In the second part, I explain tools that are used to develop blockchain applications.

This part explains the development tools Hardhat and Remix.
You will see Solidity code for making your own cryptocurrency.
You will see the JavaScript libraries ethers.js and web3.js that are used to interact with the Ethereum blockchain.
You will see how you can connect a wallet with a blockchain application. I will show MetaMask, which is a popular wallet and also WalletConnect, which acts as a bridge to connect multiple kinds of wallets with an application. I will also show how you can transfer cryptocurrencies in MetaMask.
You will see how to set up a local test blockchain on your computer and also how to interact with an Ethereum testnet on the Internet.
You will see how you can register and configure an Ethereum Name.

In the third part, I show how you can make a user interface that interacts with the Ethereum blockchain, it shows

how to retrieve the address of a smart contract through an Ethereum Name
how to read data from the blockchain through a default provider
how to connect MetaMask or a wallet through WalletConnect with the user interface
how to execute functions that write data to the blockchain through a connected wallet
how to search for events emitted by a smart contract
