What is OpenZeppelin Contracts?

OpenZeppelin Contracts is the most widely audited open-source library of reusable Solidity components, including ERC-20, ERC-721, Ownable, AccessControl, and ReentrancyGuard.

Inheriting from OpenZeppelin instead of hand-writing token logic removes whole categories of bugs. The library is versioned and audited, and it is what most production contracts on Ethereum and Monad are built on.
