SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill consolidates Base (Ethereum L2) on-chain data with USD pricing to help users quickly understand wallet balances, token metadata, transactions, gas costs, contract health, whale activity, and network status.

Core Features & Use Cases

  • Wallet portfolio: ETH and ERC-20 balances with USD values.
  • Transaction details: decode transfers and gas costs by hash.
  • Token info: metadata, price, and market cap for ERC-20 tokens.
  • Gas and network analysis: Base-specific gas, base fee trends, and utilization.
  • Contract inspection: address type, interfaces, and proxy resolution.
  • Whale detection: large transfers in recent blocks.
  • Network health: live stats like block, price, and gas metrics.
  • Price lookup: USD price for known tokens via CoinGecko.

Quick Start

Run the Base blockchain CLI to fetch current network stats and sample wallet data using the base_client.py script.

Frequently Asked Questions about base

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I query Base L2 wallet balances and include USD pricing?▼

Decode Base L2 transactions by fetching transfer data through the transaction hash, then calculate gas costs and enrich token values using the CoinGecko price API for complete transaction insights.

Can I analyze Base network gas fees and block utilization using an RPC endpoint?▼

Analyze Base network gas fees and block utilization by connecting to a BASE_RPC_URL endpoint, which returns live base fee trends, block stats, and network health metrics for L2 gas analysis.

Does this Base blockchain data tool require a private RPC endpoint?▼

A private RPC endpoint is optional for Base blockchain data queries; the tool functions using standard Python libraries and a default public RPC, but supports a BASE_RPC_URL override for private endpoints.

What is the best way to detect whale activity on the Base blockchain?▼

Detect whale activity on the Base blockchain by scanning recent blocks for large ERC-20 transfers, inspecting transaction values, and optionally applying USD price lookups to quantify the transfer size.

Can I inspect Base contract addresses to resolve proxy implementations?▼

Inspect Base contract addresses to identify address types, detect exposed interfaces, and resolve proxy contract implementations directly through standard Python RPC calls without external indexing services.
