Zeppelin Solidity
OpenZeppelin is a library for writing secure Smart Contracts on Ethereum.
With OpenZeppelin, you can build distributed applications, protocols and organizations:
- using common contract security patterns (See Onward with Ethereum Smart Contract Security)
- in the Solidity language.
NOTE: New to smart contract development? Check our introductory guide.
Getting Started
OpenZeppelin integrates with Truffle, an Ethereum development environment. Please install Truffle and initialize your project with truffle init
.
npm install -g truffle@beta
mkdir myproject && cd myproject
truffle init
To install the OpenZeppelin library, run:
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 {
...
}
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.
