What is OpenZeppelin?
Provided through a stable API, OpenZeppelin Contracts provides an interface for developers to build Solidity and Cairo smart contracts. Developers can leverage secure practices to build ECR20, ECR721, ECR1155, Governer, and custom smart contracts through interactive wizard tools or with Remix. More than 30k developers follow and use OpenZeppelin's tools and libraries to build Web3 DApps.
