- The ERC165 standard is used in the ERC721 standard so that it knows which functions are supported by the contract. Similarly, you can use the ERC165 standard in any other standard or contract to let the client know about the functions supported by the standard or the contract.
- The ERC721 NFT standard should be used when you have some digital assets that are nonfungible. Nonfungibility means that you cannot further subdivide these assets. As an example, digital collectible cards are nonfungible, and each one is different from others.
- The _mint() and _burn() functions are both internal functions, and so these can be called from the implementing contract. The _mint() function is used to create a new, unique ERC721 NFT token and send it to the given address. On the other hand, the _burn() function is used to burn a given NFT...

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.
