技术问询：Polkadot对应的客户端库是什么？

Great question! Since web3.js is built specifically for Ethereum-compatible blockchains, it doesn’t work with Polkadot’s unique multi-chain architecture. For Polkadot (and its parachains), the go-to client library you’ll want to use is Polkadot JS API — it’s the official, most widely adopted tool in the ecosystem for interacting with Polkadot networks.

Here’s a quick breakdown of key tools in this space:

• Polkadot JS API: This is the primary library, maintained by the core Polkadot team and community. It supports both browser and Node.js environments, letting you connect to Polkadot/Substrate nodes, submit transactions, query on-chain state, and build full-fledged dApps tailored to Polkadot’s ecosystem. Since Polkadot is built on Substrate, this API works seamlessly with all Substrate-based chains too.
• Substrate API Sidecar: If you prefer working with RESTful endpoints instead of a direct JavaScript API, this tool wraps the Polkadot JS API to expose easy-to-use REST interfaces. It’s perfect for developers who lean into REST-based workflows.
• Niche community libraries: There are smaller, community-maintained libraries for other languages (like Python or Rust bindings) for specific use cases, but Polkadot JS API remains the standard for most JavaScript/TypeScript projects targeting Polkadot.
