DApp Inspector is a Chrome extension designed for inspecting, decoding, and replaying RPC traffic between Web3 decentralized applications (DApps) and wallets. This tool integrates seamlessly with Chrome DevTools, capturing every JSON-RPC call made by supported wallets like MetaMask and OKX. Users can view method calls, parameters, results, errors, and latency breakdowns in real-time, making it ideal for developers and users alike who need to troubleshoot or analyze interactions with DApps.

Key features include live RPC capture, built-in ABI decoding for various token standards, risk badges for transaction approvals, and the ability to replay or mock RPC calls. The extension prioritizes user privacy by ensuring all data is stored locally within the browser, with no external tracking or analytics. DApp Inspector also supports a polished user interface with theme options and full keyboard navigation, making it a powerful tool for anyone working with blockchain technology.
