Note: this section describes a low-level method for using ZeppelinOS. To follow the recommended development experience, use the higher-level CLI guide.
zos-lib is a library to develop, deploy and operate upgradeable smart contracts on Ethereum and every other EVM and eWASM-powered blockchain.
zos-lib simply go to your project's root directory and run:
npm install zos-lib
Next, learn how to:
- Programmatically develop and deploy a single upgradeable smart contract (for fixing bugs or adding new features)
- Programmatically develop and operate a complex upgradeable app with multiple smart contracts which are connected to the ZeppelinOS upgradeable standard library
