Getting Started

OpenZeppelin integrates with Truffle, an Ethereum development environment. Please install Truffle and initialize your project with truffle init:

npm install -g truffle
mkdir myproject && cd myproject
truffle init

To install the OpenZeppelin library, run:

npm init # follow instructions
npm install zeppelin-solidity

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

import "zeppelin-solidity/contracts/ownership/Ownable.sol";

contract MyContract is Ownable {
