What is OpenZeppelin?

OpenZeppelin is a widely-used open-source library of reusable smart contracts for building decentralized applications (dApps) on various blockchain platforms, including Ethereum, Binance Smart Chain, and others

The library provides a set of secure and audited building blocks, such as ERC-20 and ERC-721 tokens, multi-sig wallets, access control, and more, that developers can use to create smart contracts quickly and easily without worrying about common security pitfalls

OpenZeppelin is used for building secure and audited smart contracts on various blockchain platforms, such as Ethereum and Binance Smart Chain

The library provides a set of pre-built and reusable smart contract modules that can be easily integrated into decentralized applications (dApps)

These modules include standard tokens, like ERC-20 and ERC-721, as well as modules for access control, voting, crowdsales, and more
