ZeppelinOS is a platform to develop, deploy and operate upgradeable smart contracts on Ethereum and every other EVM and eWASM-powered blockchain.
- Upgrades: fix and improve your contracts over time.
- Standard libraries: link your contracts to standard libraries already deployed on the blockchain.
Install ZeppelinOS and setup your project as described in the Setup guide.
In order to use ZeppelinOS to build an upgradeable application, follow our Building upgradeable applications guide.
If you would like to use the ZeppelinOS on-chain standard libraries in your app, follow our Using the stdlib in your app guide.
If you are interested in deploying your own standard libraries for ZeppelinOS, see our Developing a new standard library guide.
ZeppelinOS was started and is sponsored by Zeppelin.
