Explorer-as-a-Service
Etherscan is a leading blockchain explorer, API, and analytics platform for Ethereum and EVM-compatible chains.
Overview
Etherscan is the most widely used blockchain explorer and analytics platform for Ethereum and other EVM-compatible blockchains. It provides developers and product teams with comprehensive tools to search, analyze, and interact with blockchain data. The platform supports over 60 chains unified under a single API key system, enabling multichain applications by simply adjusting the chain ID parameter. This makes it easier for developers to build cross-chain solutions without managing multiple API keys or endpoints.
The core features include detailed transaction and token transfer lookups, address portfolio tracking across chains, top token holder analytics, and address name tagging for better identification of entities like exchanges. Etherscan’s API V2 offers stable and scalable endpoints for querying blockchain data, including token transfers, holder lists, and metadata. It also supports contract verification integrations with popular development tools such as Foundry, Hardhat, and Remix, streamlining the deployment and verification process.
What sets Etherscan apart is its extensive chain coverage, reliability, and the depth of data it provides. Unlike many explorers that focus on a single chain, Etherscan’s unified API simplifies multichain development. Its large user base and reputation as the go-to Ethereum explorer make it a trusted source for blockchain data. Developers can quickly onboard by obtaining an API key from the documentation portal and start making requests to endpoints tailored for token analytics, address insights, and contract verification.
Use cases include building dashboards that track token holder distributions, integrating wallet portfolio views in DeFi apps, and automating contract verification workflows. Etherscan’s comprehensive documentation and active social presence on X (Twitter) support developers in troubleshooting and feature adoption. Overall, Etherscan remains a foundational tool for anyone building on Ethereum or EVM-compatible networks.
