Etherscan Blockchain Data

About

This skill enables Claude to interact directly with Etherscan's V2 API to retrieve real-time native ETH and ERC-20 token balances. It features intelligent chain inference to automatically detect networks like Polygon, Arbitrum, and Scroll based on user prompts, avoiding the common pitfall of defaulting to Ethereum Mainnet. Designed for developers and crypto-native users, it provides seamless wallet audits, multi-address queries, and automatic unit conversion from Wei to human-readable formats directly within the terminal.
