A block explorer or block scanner is a tool that allows users to search, track, and analyze blockchain data across different networks. With a block explorer like Blockscout, you can verify transactions, monitor wallet activity, check token balances, and interact with smart contracts. It's essentially a search engine for blockchain data, providing transparency and insight into the blockchain ecosystem. Our eth scanner and ethereum block explorer functionalities are particularly popular among users.

Blockscout's multichain explorer enables you to search across multiple EVM-based blockchains simultaneously. Whether you're looking for transactions, token transfers, or smart contract details, Blockscout gives you results from the main supported networks in one unified dashboard. This saves time and simplifies the process of managing and analyzing blockchain data across various chains. If you are looking for more advanced features related to a specific chain (like an eth explorer for Ethereum or an Arbitrum Explorer) please visit our comprehensive list of block explorers.
