We have been referring to the OpenZeppelin libraries in some places in Chapter 3, Control Structures and Contracts, in Chapter 4, Learning MetaMask and Remix, and in the sample Solidity code we discussed in those chapters. In this chapter, we will look into the Solidity contract files that OpenZeppelin provides. The OpenZeppelin Solidity contract files and libraries are open source. These have been tested, audited, and used in many Ethereum Decentralized Applications (DApps). The OpenZeppelin project files are maintained by the Zeppelin company, and the libraries were developed to ensure high-quality code and security standards.
After completing this chapter, you will be able to install and use the OpenZeppelin library contract files in your project. You will be able to decide which library files you want to bring in...
