Etherscan Dominates as Go-To Blockchain Explorer for Ethereum

Etherscan is one of the most widely used Ethereum blockchain explorers. Founded in 2015 by Matthew Tan, it processes data from over 2.8 billion cumulative Ethereum transactions and tracks more than 300 million unique addresses.

The platform offers a range of features, including a gas tracker, token approval checker, contract verification tool, and an API that serves over 500 million calls per day from wallets, portfolio trackers, and DeFi dashboards.

One of the most useful aspects of Etherscan is its ability to read on-chain data. Every interaction with Ethereum leaves a permanent, public record, and Etherscan provides a standard interface for reading those records.
