This package provides a library to develop, deploy and operate upgradeable smart contracts on Ethereum and every other EVM and eWASM-powered blockchain. This library is considered low level. For regular development, we recommend the CLI-aided development experience with the ZeppelinOS CLI.
This package has been moved to a monorepo at zeppelinos/zos. The github repository will remain open to keep the issues up until they are either closed or migrated.
