SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Provide fast, on-chain visibility for Base (Ethereum L2) without requiring API keys, consolidating wallet balances, token metadata, transaction details, gas cost estimates, contract inspection, whale detection, and live network health into a single, scriptable tool.

Core Features & Use Cases

  • Wallet Portfolio: Retrieve ETH and known ERC-20 balances, enrich with USD prices and compute portfolio totals.
  • Transaction Inspection: Decode transactions and receipts with gas, L1/L2 fee breakdowns, and token transfer decoding.
  • Token & Contract Analysis: Read ERC-20 metadata, total supply, code size, detect ERC interfaces, and resolve EIP-1967 proxies.
  • Gas Analysis & Network Stats: Provide 10-block trends, base fee estimates, utilization, and cost estimates for common operations.
  • Whale Detection & Price Lookup: Scan recent blocks for large transfers and fetch token prices via CoinGecko.
  • Use Case: Rapidly value a Base wallet in USD for portfolio reporting, debug costly transactions by examining L1/L2 fees, or verify a token contract and its market data before on-chain interaction.

Quick Start

Use the base skill to show a wallet's ETH and ERC-20 balances with USD prices and fetch current network gas and base fee statistics.

Frequently Asked Questions about base

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

FAQPage Schema
How do I check a Base L2 wallet balance in USD without an API key?▼

The Skill uses Base JSON-RPC to retrieve ETH and ERC-20 token holdings, then enriches them with free CoinGecko price feeds to compute USD portfolio totals without requiring any API keys.

How does gas analysis on Base break down L1 and L2 fees?▼

Gas analysis on Base decodes transaction receipts to separate L1 data availability fees from L2 execution fees, providing a 10-block base fee trend and cost estimates for common operations.

Can I inspect ERC-20 token contracts and detect proxy implementations on Base?▼

Yes, you can inspect Base contracts to read ERC-20 metadata and total supply, detect supported ERC interfaces, and resolve EIP-1967 proxy implementations directly via JSON-RPC calls.

What is the best way to detect large token transfers on the Base network?▼

Whale detection on Base scans recent blocks for large token transfers using batch RPC calls, allowing you to identify significant on-chain movements without needing external indexing services.

Do I need to install external Python libraries to query Base blockchain data?▼

No, you do not need external Python libraries to query Base blockchain data because the Skill relies exclusively on the Python standard library, executing batch JSON-RPC calls with built-in retry and backoff logic.

Why does querying Base network statistics fail without retry and backoff logic?▼

Querying Base network statistics can fail due to rate limits or transient node errors, so implementing retry and backoff logic within batch JSON-RPC calls ensures reliable retrieval of live network health and fee estimates.
