Blockchain Explorer for inspecting and analyzing EVM Chains.


Blockscout provides a comprehensive, easy-to-use interface for users to view, confirm, and inspect transactions on EVM (Ethereum Virtual Machine) blockchains. This includes Ethereum Mainnet, Ethereum Classic, Optimism, Gnosis Chain and many other Ethereum testnets, private networks, L2s and sidechains.

See our project documentation for detailed information and setup instructions.

For questions, comments and feature requests see the discussions section or via Discord.

About Blockscout

Blockscout allows users to search transactions, view accounts and balances, verify and interact with smart contracts and view and interact with applications on the Ethereum network including many forks, sidechains, L2s and testnets.

Blockscout is an open-source alternative to centralized, closed source block explorers such as Etherscan, Etherchain and others. As Ethereum sidechains and L2s continue to proliferate in both private and public settings, transparent, open-source tools are needed to analyze and validate all transactions.

Supported Projects

Blockscout currently supports several hundred chains and rollups throughout the greater blockchain ecosystem. Ethereum, Cosmos, Polkadot, Avalanche, Near and many others include Blockscout integrations. A comprehensive list is available here. If your project is not listed, please submit a PR or contact the team in Discord.
