This book is a step-by-step guide for everyone who wants to get started as an Ethereum developer. It was designed for those who have never programmed anything in the blockchain and want to get started.

I will cover everything from the basic requirements of installation to writing, testing, and deploying smart contracts. I will also cover topics such as IPFS, Filecoin, ENS, Chainlink, Truffle, Ganache, OpenZeppelin, Pinata, Fleek, Infura, MetaMask, and OpenSea, among others.

In Chapter , I will go through all the necessary requirements to start the activities described in this book. It covers software and tools such as Docker, Truffle, Ganache, MetaMask, and Infura.

In Chapter , you will learn how to create a basic Solidity project using the VS Code extension and then compile and deploy the smart contract to a local blockchain.

In Chapter , you will learn how to code smart contracts to create your own coin and deploy it to a local blockchain. Fungible tokens are interchangeable, so they are perfect to solve problems such as double spending. You will also be able to add this token to your own wallet and send it to different wallets, as well as send other coins that you already have.

In Chapter , you will learn how to create a unit test file for a smart contract, as well as write test assertions, run the unit tests, and check the unit test results.

In Chapter , you will be able to create smart contracts for badge tokens. You can use badge tokens, also known as NFTs, to represent physical things in the virtual world, such as digital collectibles, game items, digital art, etc. Each NFT token is unique and can have a unique value. In this chapter, you will learn how to code the smart contract with the help of the OpenZeppelin library. You will also create the badge and add it to IPFS node. After that, you will learn to pin it so it is available for everyone, everywhere. Next, you will learn how to migrate the contract to different environments such as a local blockchain using Ganache and testnets using Infura. Finally, you will learn how to sell your own NFT on OpenSea.

In Chapter , we will cover different ways to fund your wallet using faucets. This part is important because you will need some ether in your wallet in order to pay for the transaction. Most of the examples will be deployed on testnets so you wont need real money to execute them.

In Chapter , you will learn how to create and save files on a decentralized file system. I also cover some tools such as a browser extension that will help you manage the node, as well as Pinata to help you pin your files remotely instead of keeping them locally. In addition, you will be able to host your own site on IPFS using Fleek.

In Chapter , I will cover ways to preserve files on a local node. The idea behind Filecoin is the same of IPFS, with the difference that Filecoin has an incentive mechanism and incentive nodes to preserve files. Filecoin was built on top of IPFS.

In Chapter , you will learn how to register a custom domain on the Ethereum Name System. You can use it to host a site under this domain name or even as a domain for your wallet to receive cryptos, tokens, or NFTs.

In Chapter , I will cover use cases where you need to pull data from off-chain using oracles. You will learn how to use price feeds and then crypto prices inside smart contracts.

In Chapter , you will learn how to create a simple project to connect to Web3 using the .NET platform and how to retrieve data from the blockchain to display wallet balances.

Chapter concludes the book.
