ChainScan has introduced a new command-line interface (CLI) tool that allows users to scan any Ethereum Virtual Machine (EVM) wallet across multiple networks, including Ethereum, Base, Arbitrum, Polygon, and Optimism, with a single command. This tool eliminates the need to open multiple block explorers, streamlining the process of checking wallet activity. The CLI is compact, consisting of just 529 lines of code, and operates without any dependencies, contained within a single file.
