# Protocols and tooling: Web3 libraries and frameworks

> Overview of development tools compatible with Chainstack nodes, including Web3 libraries, CLI tools, IDEs, and framework integrations for each protocol.

Each protocol's guide is designed to offer step-by-step instructions for each tool, including installation, configuration, and usage examples, such as how to get the balance of an address, query data using GraphQL, or deploy smart contracts using Truffle or Hardhat. It also provides details on how to connect to blockchain nodes using different protocols and endpoints, and how to secure these connections using keys or passwords.
