# Introduction

Etherscan is the leading blockchain explorer, search, API, and analytics platform for Ethereum and other EVM-compatible chains.

With Etherscan API V2, we've unified all 60+ [supported chains](/supported-chains) under a single account and API key system. Your app becomes multichain simply by updating the `chainid` parameter to support BNB Smart Chain (BSC), Base, Arbitrum, HyperEVM, and more.
