Install

Install the RDK for your language. The TypeScript packages and the Go module are published; the Python and Rust clients are fully implemented and awaiting their registry publications (PyPI / crates.io) — until then, build them from the monorepo.

Package	Language	Install	Status
@qorechain/rdk	TypeScript	npm i @qorechain/rdk	Available (v0.2.0)
@qorechain/rdk-cli (qorollup)	CLI	npm i -g @qorechain/rdk-cli	Available
qorechain-rdk	Python	pip install qorechain-rdk (imports as qorrdk)	Available on PyPI (v0.3.1)
qorechain-rdk	Go	go get github.com/qorechain/qorechain-rdk/packages/go	Available (v0.3.1)
qorechain-rdk	Rust	cargo add qorechain-rdk	Available on crates.io (v0.3.1)
io.github.qorechain:qorechain-rdk	Java (JVM)	Maven/Gradle (io.github.qorechain:qorechain-rdk:0.3.1)	Available on Maven Central (v0.3.1)
create-qorechain-rollup	CLI	npm create qorechain-rollup	Available (v0.2.0)

The Python, Go, Rust, and Java (JVM) clients are fully implemented and tested in the monorepo (config, presets, utilities, read clients, accounts, and transaction signing + broadcast). Python is on PyPI (pip install qorechain-rdk, imported as qorrdk), Rust is on crates.io (cargo add qorechain-rdk), Java is on Maven Central (io.github.qorechain:qorechain-rdk), and Go is installable from the tagged module.

TypeScript

The core package:

npm i @qorechain/rdk

It targets Node.js 20+ and ships ESM, CommonJS, and type definitions.

Signing dependencies

The RDK accepts any @cosmjs OfflineSigner. For local development with a raw key or mnemonic, install @cosmjs/proto-signing:

npm i @cosmjs/proto-signing

For hybrid post-quantum signing, install @qorechain/sdk and use its signer in place of the standard one:

npm i @qorechain/sdk

Operator CLI (qorollup)

@qorechain/rdk-cli installs the qorollup binary for creating, operating, and monitoring rollups from the command line. It is a thin wrapper over @qorechain/rdk.

npm i -g @qorechain/rdk-cli
# or run it without installing:
npx @qorechain/rdk-cli doctor

It targets Node.js 20+. See the qorollup reference for every command and flag, and Zero to a live rollup for a guided walkthrough.

Python

pip install qorechain-rdk

Available on PyPI. The distribution installs as qorechain-rdk and imports as qorrdk (e.g. from qorrdk import create_rdk_client).

Go

go get github.com/qorechain/qorechain-rdk/packages/go

Available today from the tagged module.

Rust

cargo add qorechain-rdk

Available on crates.io.

Java / JVM

Available on Maven Central as io.github.qorechain:qorechain-rdk.

Maven:

<dependency>
  <groupId>io.github.qorechain</groupId>
  <artifactId>qorechain-rdk</artifactId>
  <version>0.3.1</version>
</dependency>

Gradle:

implementation("io.github.qorechain:qorechain-rdk:0.3.1")

Scaffolding CLI

create-qorechain-rollup scaffolds a complete starter project from one of five templates:

npm create qorechain-rollup my-rollup -- --template defi-rollup

See the CLI reference for usage and flags.
