Blockscout is a comprehensive, open-source blockchain explorer for the Ethereum ecosystem, supporting a wide range of EVM (Ethereum Virtual Machine) compatible chains. Its mission is to provide a transparent, feature-rich, and user-friendly window into blockchain data for developers, users, and enterprises. Originally developed by the POA Network, Blockscout is now a key infrastructure project supported by various teams and communities. It allows users to search for transactions, view account balances, verify and interact with smart contracts, and analyze network statistics, offering both hosted instances and the ability for any project to self-host the explorer for their own network.
