ChainIDE is a cloud-based AI-powered integrated development environment (IDE) for building, testing, and deploying smart contracts and decentralized applications across multiple blockchains.
ChainIDE is a cloud-based integrated development environment designed specifically for Web3 developers to build, test, debug, and deploy smart contracts and decentralized applications (dApps) across a wide range of blockchains. It supports multiple programming languages including Solidity, JavaScript, HTML, and CSS, and offers a rich set of developer tools such as IntelliSense code completion, syntax highlighting, bracket matching, and code refactoring. ChainIDE’s environment is accessible from any operating system (macOS, Linux, Windows) without local setup, enabling developers to switch between supported blockchains with a single click.
A key differentiator of ChainIDE is its AI-powered Code Sage module, which leverages OpenAI models to assist developers by answering code-related questions, generating code snippets, refactoring code, and providing debugging advice. This AI integration accelerates the development cycle by reducing manual coding effort and improving code quality. Additionally, ChainIDE features a marketplace of VSCode-compatible plugins and user-created apps that extend functionality and foster community collaboration.
ChainIDE supports a broad spectrum of blockchains, including Ethereum, BNB Chain, Polygon, Conflux, Nervos, Dfinity (Internet Computer), Flow, Aptos, XDC, Astar, IRISnet, Sui, FISCO BCOS, Arbitrum, Starknet, Mina, and more. This multi-chain support allows developers to deploy smart contracts seamlessly across public and consortium blockchains. The platform also offers interactive learning resources such as multi-blockchain courses, video tutorials with split-screen coding, and NFT rewards for course completion, making it suitable for both novice and experienced developers.
With over 3.5 million contracts compiled and users in more than 120 countries, ChainIDE has established itself as a versatile and scalable Web3 development tool. It is used by engineers at leading companies and supported by an active community via Discord, Telegram, and forums. Developers can get started immediately by signing up on the cloud IDE, exploring the AI Code Sage module, and accessing comprehensive documentation and tutorials available on the official website and GitBook.
Developers building decentralized applications face challenges such as managing complex multi-chain deployments, lacking integrated AI assistance for smart contract coding, and dealing with fragmented tooling that slows development cycles. Additionally, onboarding new developers is hindered by limited educational resources tailored to blockchain development.
Advanced code completion, semantic understanding, and refactoring tools improve developer productivity and code quality.
Interactive compiler and debugging modules allow developers to test and troubleshoot smart contracts within the IDE.
Offers interactive tutorials, split-screen video coding, and NFT rewards to help developers learn blockchain development effectively.
Developers use ChainIDE to write Solidity contracts, test them with integrated debugging tools, and deploy seamlessly to Ethereum and Polygon networks.
Teams leverage the AI Code Sage module to generate and refactor smart contract code quickly, enabling faster iteration across multiple blockchains like BNB Chain and Conflux.
Educational institutions and companies use ChainIDE’s learning hub to train developers with hands-on coding tutorials and blockchain courses, rewarding progress with NFTs.
