Welcome to the official documentation for the JavaScript VeChain SDK!

This SDK provides developers with tools and resources to integrate VeChain blockchain functionality into their applications with ease. Whether you're building decentralized applications (dApps), managing digital assets, or exploring blockchain-based solutions, this SDK offers a comprehensive set of features to interact with the VeChainThor blockchain.

Installation

To start using the VeChain SDK, you can install specific packages based on your needs. The SDK is a monorepo that includes various packages. Here are the packages available:

You can install these packages individually based on your requirements. Here's how you can install the packages using npm:

npm install @vechain/sdk-core
npm install @vechain/sdk-network
...

If you prefer using yarn, you can install the packages as follows:

yarn add @vechain/sdk-core
yarn add @vechain/sdk-network
...
