Etherscan

Etherscan is an independent blockchain explorer and analytics platform built for the Ethereum network. Founded in 2015 and headquartered in Kuala Lumpur, Malaysia, the company was created by Matthew Tan with the goal of providing open, equitable access to on-chain data for developers, researchers, and the broader Ethereum community. Etherscan is not affiliated with the Ethereum Foundation and operates as a private company.

The platform enables users to search and verify Ethereum transactions, wallet addresses, smart contracts, tokens, and blocks in real time. Beyond basic exploration, Etherscan provides a developer API suite that allows third-party applications to pull blockchain data programmatically. It also offers advanced analytics features including gas tracker tools, token approval checkers, and address labeling, which together make it a foundational reference layer for the Ethereum ecosystem.

As of 2026, Etherscan remains one of the most widely used Ethereum infrastructure tools, with usage extending to DeFi protocols, NFT platforms, auditors, and compliance tools that rely on its contract verification and address labeling services. The company has expanded its explorer product to other EVM-compatible chains under the Etherscan brand family, including BscScan (Binance Smart Chain), PolygonScan, and others.
