Build on the Hybrid Blockchain
Leverage Qtum's unique architecture combining Bitcoin's security and Ethereum's flexibility to create powerful decentralized applications.
Everything you need to start building on Qtum's hybrid blockchain infrastructure
Qtum Core
Complete node implementation that serves as the reference for the Qtum network. Includes full node capabilities, wallet functions, and JSON-RPC API access.
Qtum.js
JavaScript library specifically built for Qtum dApp development. Simplifies interaction with smart contracts and the Qtum RPC using popular frameworks like React or Angular.
Qmix IDE
Qtum's version of Ethereum's Remix - an in-browser IDE for writing, compiling, deploying, and interacting with Solidity smart contracts directly in the browser.
Qtum API
Public API for accessing Qtum blockchain data and explorer information. Provides detailed blockchain information through simple RESTful endpoints.
Development Environments
Set up your development environment to start building on Qtum
Local Development

Smart Contract Development
Example of a simple Qtum smart contract
pragma solidity ^0.8.0;
contract HelloQtum {
string private message;
"blue">constructor() {
message = "Hello, Qtum!";
}
"blue">function getMessage() public view "blue">returns (string memory) {
"blue">return message;
}
"blue">function setMessage(string memory _message) public {
message = _message;
}
