Mastering Blockchain Programming with Solidity

Deep Dive into the OpenZeppelin Library

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.
