This repository contains all specification files used to generate code for the Rosetta API.

Build once. Integrate your blockchain everywhere.

Rosetta is an open-source specification and set of tools that makes integrating with blockchains simpler, faster, and more reliable. The Rosetta API is specified in the OpenAPI 3.0 format.

Requests and responses can be crafted with auto-generated code using Swagger Codegen or OpenAPI Generator, are human-readable (easy to debug and understand), and can be used in servers and browsers.

No installation is required, as the repository only includes specification files.

You can find the Rosetta API documentation at rosetta-api.org.

Check out the Getting Started section to start diving into Rosetta.

Our documentation is divided into the following sections:

• Product Overview
• Getting Started
• Rosetta API Spec
• Testing
• Best Practices
• Repositories

You may contribute to the rosetta-specifications project in various ways:

• Asking Questions
• Providing Feedback
• Reporting Issues

Read our Contributing documentation for more information.

When you've finished an implementation for a blockchain, share your work in the ecosystem category of the community site. Platforms looking for implementations for certain blockchains will be monitoring this section of the website for high-quality implementations they can use for integration. Make sure that your implementation meets the expectations of any implementation.

• rosetta-sdk-go — The rosetta-sdk-go SDK provides a collection of packages used for interaction with the Rosetta API specification. Much of the SDK code is generated from this, the rosetta-specifications repository.
• rosetta-cli — Use the rosetta-cli tool to test your Rosetta API implementation. The tool also provides the ability to look up block contents and account balances.

To help you with examples, we developed complete Rosetta API reference implementations for Bitcoin and Ethereum. Developers of Bitcoin-like or Ethereum-like blockchains may find it easier to fork these reference implementations than to write an implementation from scratch.

You can also find community implementations for a variety of blockchains in the rosetta-ecosystem repository, and in the ecosystem category of our community site.

While working on improvements to this repository, we recommend that you use these commands to check your code:

• make deps to install dependencies
• make gen to generate the specification files
• make check-valid to ensure specification is valid
• make release to check if code passes all tests run by CircleCI

Unlike the Data API where there are no global type constraints (e.g., you can specify any operation type), the Construction API has a clearly enumerated list of supported curves and signatures. Each one of these items has a clearly specified format that all implementations should expect to receive.

If a curve or signature you are employing is not enumerated in the specification, you will need to open a PR against the specification to add it along with the standard format it will be represented in.

It is up to the caller of a Construction API implementation to implement key generation and signing for a particular CurveType:SignatureType. There is a keys package in rosetta-sdk-go that is commonly used by callers and anyone in the community can implement additional schemes there.
