System Documentation

What problem does it solve?

This skill enables developers to retrieve on-chain balances across Ethereum and other EVM-compatible networks using Etherscan's V2 API, removing manual API integration and parsing steps. It supports ETH balances, ERC-20 token balances, and multi-chain balance lookups, streamlining wallet analytics, portfolio dashboards, and automation workflows.

Core Features & Use Cases

  • ETH balance queries across supported chains (via chainid)
  • ERC-20 token balance queries (contractaddress + address)
  • Multi-address and multi-chain balance lookups for dashboards and alerts
  • Fallback to unified documentation for advanced capabilities

Quick Start

Prompt the AI to fetch balances for a wallet address, e.g., '0xDEADBEEF0123456789abcdef0123456789ABCDEF01'. Include the target chain or chainid to retrieve cross-chain data. The skill enforces API key presence and formats results in JSON or Markdown as requested.
