What is Etherscan?

Etherscan is the foremost, independent block explorer, analytics, and API platform tailored to the Ethereum ecosystem. Founded in 2015 by Matthew Tan, its mission is to democratize blockchain transparency by indexing all Ethereum activity—from transactions and smart contracts to tokens and ENS addresses—and making it easily searchable.

Users can track transactions, monitor wallet balances, interact with smart contracts, verify approvals, and analyze gas fees via a user-friendly interface. Its robust toolset includes features like contract verification, token and NFT analytics, event logs, and a real-time gas tracker.

For developers, Etherscan offers an API suite: public endpoints for routine data access, and a subscription-based API V2 that supports over 50 EVM-compatible chains using a single API key—streamlining cross-chain querying. Operating independently of the Ethereum Foundation, Etherscan has expanded to include Filecoin (via Blockscan), Solana (via Solscan acquisition), and other multichain explorers—while staying true to its founding mission of accessible blockchain insights.
