What does Blockscout do?

Blockscout is a multichain block explorer that lets you search across dozens of blockchain networks from a single interface. You can look up addresses, transactions, tokens, smart contracts, blocks, ENS domains, and dApps without switching between different explorers. It pulls data from both onchain and offchain sources to give you rich context for each item you search.

The tool supports smart contract verification with multiple methods, and lets you read, write, and interact with contracts and proxies directly. You can analyze ERC20 token movements, explore NFTs across networks, and review transactions with human-readable decoding that makes complex blockchain data easier to understand. Blockscout also includes an ENS lookup feature for human-readable Ethereum addresses, a watch list for tracking addresses, and an AI mode for natural language search queries.

Blockscout is built for blockchain developers, crypto investors, and web3 researchers who need to verify transactions, audit smart contracts, or track token activity across multiple chains. It's also useful for anyone exploring dApps or NFTs on supported networks. The tool is open source and supports a wide range of EVM-compatible chains, making it a practical choice for multichain exploration without switching between different block explorers.
