README.md
OpenZeppelin is a library for secure smart contract development. It provides implementations of standards like ERC20 and ERC721 which you can deploy as-is or extend to suit your needs, as well as Solidity components to build custom contracts and more complex decentralized systems.
Install
npm install openzeppelin-solidity
If you're interested in trying out a preview of OpenZeppelin 2.0, install openzeppelin-solidity@next, check out the release notes, and let us know what you think!
Usage
To write your custom contracts, import ours and extend them through inheritance.
pragma solidity ^0.4.24;
import 'openzeppelin-solidity/contracts/token/ERC721/ERC721Full.sol';
import 'openzeppelin-solidity/contracts/token/ERC721/ERC721Mintable.sol';
contract MyNFT is ERC721Full, ERC721Mintable {
constructor() ERC721Full("MyNFT", "MNFT") public {
}
}
You need an ethereum development framework for the above import statements to work! Check out these guides for Truffle or Embark.
On our site you will find a few guides to learn about the diferent parts of OpenZeppelin, as well as documentation for the API. Keep in mind that the API docs are work in progress, and don’t hesitate to ask questions in our Slack.
Security
OpenZeppelin the project is maintained by Zeppelin the company, and developed following our high standards for code quality and security. OpenZeppelin is meant to provide tested and community-audited code, but please use common sense when doing anything that deals with real money! We take no responsibility for your implementation decisions and any security problems you might experience.
The core development principles and strategies that OpenZeppelin is based on include: security in depth, simple and modular code, clarity-driven naming conventions, comprehensive unit testing, pre-and-post-condition sanity checks, code consistency, and regular audits.
Please report any security issues you find to security@openzeppelin.org.
