SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill provides a unified CLI to query on-chain data from the Base (Ethereum L2) network and enrich results with USD pricing, saving analysts from assembling data from multiple sources.

Core Features & Use Cases

  • Wallet balances (ETH and ERC-20) with USD values and live price lookups.
  • Transaction details and receipts, including on-chain event logs and token transfers.
  • Token metadata (name, symbol, decimals, total supply) with price and market cap.
  • Gas analysis and Base-specific cost visibility (L2 execution plus L1 data fees) and network stats.
  • Network health details (latest block, gas price, base fee, ETH price) for quick health checks.

Quick Start

Run the Base CLI to fetch wallet balances, token holdings, and network stats using the default RPC or a private endpoint.

FAQPage Schema
How do I check Base L2 wallet balances and get USD values?

Check Base L2 wallet balances by fetching ETH and ERC-20 holdings via CLI, which automatically enriches results with live USD price lookups from CoinGecko. This provides immediate valuation without manual cross-referencing.

How do I analyze Base network gas fees including L1 data costs?

Analyze Base network gas fees by querying gas price and base fee data, which breaks down Base-specific cost visibility into L2 execution plus L1 data fees. This provides a complete picture of transaction costs.

Can I fetch Base transaction details and event logs with this tool?

Fetch Base transaction details and receipts to review on-chain event logs and token transfers. This retrieves comprehensive transaction data directly from the Base network RPC endpoint.

Do I need a private RPC endpoint to query Base on-chain data?

A private RPC endpoint is not strictly required to query Base on-chain data, as the CLI supports a default RPC. Configure a private endpoint by setting the BASE_RPC_URL environment variable for customized access.

What is the best way to get Base token metadata with market cap?

Get Base token metadata with market cap by querying token contracts for name, symbol, and decimals, then enriching it with live price data from CoinGecko. This combines contract data with market valuation.

How do I monitor Base network health and latest block stats?

Monitor Base network health by fetching latest block, gas price, and ETH price details. This provides quick network statistics for health checks directly through the command-line interface.
