Blockchain AI Agent integrates large language models with multi-chain support to deliver fast, accurate blockchain data retrieval through natural language. Users ask questions like 'What was the gas used in the last Ethereum block?' or 'Show me recent transactions for a Solana address,' and the agent automatically invokes underlying RPC calls to Bitcoin, Ethereum, and Solana nodes. Built on Python and using web3.py, solana-py, and Bitcoin libraries, it seamlessly handles block data, transaction parsing, account balances, and price information. The modular architecture allows developers to extend the agent with custom functions or add support for additional chains. This tool empowers blockchain developers, analysts, educators, and enthusiasts to access complex on-chain data without writing low-level code.

Chatchat Lite is an open-source, lightweight chat UI framework designed to run in the browser and connect to multiple AI backends—including OpenAI, Azure, custom HTTP endpoints, and local language models. It provides real-time streaming responses, Markdown rendering, code block formatting, theme toggles, and persistent conversation history. Developers can extend it with custom plugins, environment-based configurations, and adaptability for self-hosted or third-party AI services, making it ideal for prototypes, demos, and production chat apps.
