Etherscan indexes Ethereum blockchain data through a block explorer architecture, enabling transaction search, address analysis, and smart contract interaction across the Ethereum mainnet and testnets. The platform supports ERC-20 and NFT token tracking, smart contract source code verification, gas price monitoring, DEX activity analysis, cross-chain transaction tracing, and node tracking. Additional tooling includes address labeling, token approval management, advanced transaction filtering, a bytecode code reader, and AI-generated transaction summaries.
Blockscan is a multichain block explorer providing a unified search interface for transactions, addresses, and tokens across multiple blockchain networks. The platform surfaces cross-chain bridge activity on address pages, supports grouped address portfolio monitoring through the Blockscan Group feature, and includes a multichain transaction search that redirects queries to the correct chain explorer when a transaction hash belongs to a different network.
Basescan is a block explorer and analytics platform for the Base network, built by the team behind Etherscan. It indexes transaction, address, and token data across Base Mainnet and its testnet, offering contract verification, gas tracking, and label cloud tooling. The platform also surfaces Base-specific rollup data including L1-to-L2 and L2-to-L1 transaction views, L1 transaction and state batch views, and account abstraction transactions. Additional tooling covers token approval management and advanced transaction filtering for developers and users.
