OpenZeppelin SDK is not being actively developed. We recommend using [Upgrades Plugins](https://docs.openzeppelin.com/upgrades-plugins/1.x/) instead.\n\u003e\n\u003e For more information, see [Building for interoperability: why we’re focusing on Upgrades Plugins](https://forum.openzeppelin.com/t/building-for-interoperability-why-we-re-focusing-on-upgrades-plugins/4088).\n\n# OpenZeppelin SDK\n\n[![standard-readme compliant](https://img.shields.io/badge/readme%20style-standard-brightgreen.svg)](https://github.com/RichardLitt/standard-readme)\n[![CircleCI](https://circleci.com/gh/OpenZeppelin/openzeppelin-sdk/tree/master.svg?style=shield)](https://circleci.com/gh/OpenZeppelin/openzeppelin-sdk/tree/master)\n[![lerna](https://img.shields.io/badge/maintained%20with-lerna-cc00ff.svg)](https://lernajs.io/)\n\n\u003e Formerly known as ZeppelinOS\n\nOpenZeppelin is a platform to develop, deploy and operate smart contract\nprojects on Ethereum and every other EVM and eWASM-powered blockchain.\n\nThis repository includes the OpenZeppelin\n[Command-Line Interface](https://github.com/OpenZeppelin/openzeppelin-sdk/tree/master/packages/cli#readme) and\n[Upgrades Library](https://github.com/OpenZeppelin/openzeppelin-sdk/tree/master/packages/lib#readme).\n\n## Install\n\nFirst, install [Node.js](http://nodejs.org/) and [npm](https://npmjs.com/).\nThen, install the OpenZeppelin SDK running:\n\n```sh\nnpm install --global @openzeppelin/cli\n```\n\n\u003e If you get an `EACCESS permission denied` error while installing, please refer to the [npm documentation on global installs permission errors](https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally). Alternatively, you may run `sudo npm install --unsafe-perm --global @openzeppelin/cli`, but this is highly discouraged, and you should rather either use a node version manager or manually change npm's default directory.\n\n## Usage\n\nWe recommend to use the OpenZeppelin SDK through the `openzeppelin sdk` command-line interface.\n\nTo start, create a directory for the project and access it:\n\n```sh\nmkdir my-project\ncd my-project\n```\n\nUse `npm` to create a `package.json` file:\n\n```sh\nnpm init\n```\n\nAnd initialize the OpenZeppelin SDK project:\n\n```sh\nopenzeppelin init my-project\n```\n\nNow it is possible to use `openzeppelin deploy` to create instances for these contracts that \nlater can be upgraded, and many more things.\n\nRun `openzeppelin --help` for more details about thes and all the other functions of the\nOpenZeppelin CLI.\n\nThe\n[OpenZeppelin SDK documentation](https://docs.openzeppelin.com/cli/)\nexplains how to build a project using our platform, how to upgrade contracts,\nhow to share packages for other projects to reuse, how to vouch for the quality\nof a package, how to use the JavaScript libraries to operate the project, and\nit explains details of the platform and some advanced topics.\n\n## Security\n\nIf you find a security issue, please contact us at security@openzeppelin.com. We\ngive rewards for reported issues, according to impact and severity.\n\n## Maintainers\n\n* [@spalladino](https://github.com/spalladino)\n* [@jcarpanelli](https://github.com/jcarpanelli)\n* [@ylv-io](https://github.com/ylv-io)\n\n## Community\n\nJoin our [Community Forum](https://forum.openzeppelin.com) or\n[community channel on Telegram](https://t.me/zeppelinos), where you can talk to\nall the OpenZeppelin developers, contributors, partners, and users.\n\nYou can also follow the recent developments of the project in the OpenZeppelin [blog](https://blog.openzeppelin.com/) and\n[Twitter account](https://twitter.com/openzeppelin).\n\n## Contributing\nTo set up a local development environment for contributing, clone the repository and run `yarn` in the root of the project. \n\nPlease refer to the [contributing guide](CONTRIBUTING.md) for more details on how to contribute.\n\n## License\n\n[MIT](LICENSE) © OpenZeppelin\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopenzeppelin%2Fopenzeppelin-sdk","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fopenzeppelin%2Fopenzeppelin-sdk","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopenzeppelin%2Fopenzeppelin-sdk/lists"}
