OpenZeppelin - 以太坊开发框架

原文链接: github.com

NPM Package Build Status Coverage Status

OpenZeppelin is a library for writing secure Smart Contracts on Ethereum.

With OpenZeppelin, you can build distributed applications, protocols and organizations:

NOTE: New to smart contract development? Check our introductory guide.

Getting Started

OpenZeppelin integrates with Truffle and Embark.

Truffle

To use with Truffle, first install it and initialize your project with truffle init.

npm install -g truffle
mkdir myproject && cd myproject
truffle init复制代码

Embark

To use with Embark, first install it and initialize your project with embark new MyApp.

npm install -g embark
embark new MyApp
cd MyApp复制代码

Installing OpenZeppelin

After installing either Framework, to install the OpenZeppelin library, run the following in your Solidity project root directory:

npm init -y
npm install -E openzeppelin-solidity复制代码

Note that OpenZeppelin does not currently follow semantic versioning. You may encounter breaking changes upon a minor version bump. We recommend pinning the version of OpenZeppelin you use, as done by the -E (--save-exact) option.

After that, you'll get all the library's contracts in the node_modules/openzeppelin-solidity/contracts folder. You can use the contracts in the library like so:

import 'openzeppelin-solidity/contracts/ownership/Ownable.sol';

contract MyContract is Ownable {
  ...
}复制代码

If you are using Embark, you can also import directly from github:

import "github.com/OpenZeppelin/openzeppelin-solidity/contracts/ownership/Ownable.sol#v1.9.0";

contract MyContract is Ownable {
  ...
}复制代码

Security

OpenZeppelin is meant to provide secure, 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 problem you might experience.

If you find a security issue, please email security@openzeppelin.org.
