Getting Started

Zeppelin 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 Zeppelin library, run:

npm i zeppelin-solidity

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

import "./zeppelin/Ownable.sol";

contract MyContract is Ownable {
  ...
}

NOTE: The current distribution channel is npm, which is not ideal. We’re looking into providing a better tool for code distribution , and ideas are welcome.

Truffle Beta Support

We also support Truffle Beta npm integration. If you’re using Truffle Beta, the contracts in node_modules will be enough, so feel free to delete the copies at your contracts folder. If you’re using Truffle Beta, you can use Zeppelin contracts like so:

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

contract MyContract is Ownable {
  ...
}

For more info see the Truffle Beta package management tutorial.
