Starport is the all-in-one platform to build, launch and maintain any crypto application on a sovereign and secured blockchain. It is a developer-friendly interface to the Cosmos SDK, the world's most widely-used blockchain application framework. Starport generates boilerplate code for you, so you can focus on writing business logic.

Quick start

Open Starport in your browser, or install it. Create and start a blockchain:

starport scaffold chain

cd mars

starport chain serve


To learn how to use Starport, check out the Starport Documentation. To learn more about how to build blockchain apps with Starport, see the developer guide. To install Starport locally on GNU/Linux or macOS, follow these steps.

channel in the Cosmos Community Discord. The issue list of this repo is exclusively for bug reports and feature requests.

Cosmos SDK Compatibility

Blockchains created with Starport use the Cosmos SDK framework. To ensure the best possible experience, use the version of Starport that corresponds to the version of Cosmos SDK that you blockchain is built with. Unless noted otherwise, a row refers to a minor version and all associated patch versions.

| Starport | Cosmos SDK | Notes | | -------- | ---------- | ------------------------------------------------ | | v0.18 | v0.44 | | | v0.17 | v0.42 |

starport chain serve
works with v0.44.x chains |

To upgrade your blockchain to the newer version of Cosmos SDK refer to the migration guide.
