SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cryptocurrency wallet data is often scattered across explorers, RPCs, and dashboards, making it hard to verify balances, token holdings, and on-chain activity. This Skill centralizes on-chain wallet data retrieval into a reusable tool that AI agents can call on demand to produce a trusted view of a given address.

Core Features & Use Cases

  • Retrieve ETH balance, ERC-20 token balances, and token approvals for a given address.
  • Resolve ENS names and look up addresses to verify identity and ownership.
  • Return transaction history and pending transactions across supported chains to support auditing, portfolio tracking, and activity monitoring.
  • Support multi-chain querying via common public RPCs and APIs for Ethereum, Arbitrum, Polygon, Base, BSC, and more.
