Zeppelin Solidity

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

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

using common contract security patterns (See Onward with Ethereum Smart Contract Security)
in the Solidity language.

Getting Started

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

sudo 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/Rejector.sol";

contract MetaCoin is Rejector { 
  ...
}

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.

Security

Zeppelin 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.

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