Mastering Blockchain Programming with Solidity

By: Jitendra Chittoda

Overview of this book

Solidity is among the most popular and contract-oriented programming languages used for writing decentralized applications (DApps) on Ethereum blockchain. If you’re looking to perfect your skills in writing professional-grade smart contracts using Solidity, this book can help. You will get started with a detailed introduction to blockchain, smart contracts, and Ethereum, while also gaining useful insights into the Solidity programming language. A dedicated section will then take you through the different Ethereum Request for Comments (ERC) standards, including ERC-20, ERC-223, and ERC-721, and demonstrate how you can choose among these standards while writing smart contracts. As you approach later chapters, you will cover the different smart contracts available for use in libraries such as OpenZeppelin. You’ll also learn to use different open source tools to test, review and improve the quality of your code and make it production-ready. Toward the end of this book, you’ll get to grips with techniques such as adding security to smart contracts, and gain insights into various security considerations. By the end of this book, you will have the skills you need to write secure, production-ready smart contracts in Solidity from scratch for decentralized applications on Ethereum blockchain.

  1. You can create as many accounts as you want in MetaMask. MetaMask supports the BIP-44 (short for Bitcoin Improvement Proposal) algorithm to create new EOA accounts using the same secret seed phrase. You can keep on creating new accounts in MetaMask by clicking on Create Account, and it will generate a new account. Using the same secret seed phrase, you can create the same accounts again in the same order on another MetaMask instance on other browsers or computers.
  2. Yes, you can connect MetaMask to your own private blockchain by configuring the Custom RPC URL in the MetaMask. To do this, choose Custom RPC from the network list; it will ask you the RPC URL to connect to.
  1. The MetaMask secret seed is also called a mnemonic. The mnemonic is created from the English word list so that it can be remembered by humans easily. Using these mnemonics, the user can generate...
