SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This CLI skill provides fast, local access to Base (Ethereum L2) on-chain data enriched with USD pricing, removing the need for external API keys.

Core Features & Use Cases

Retrieve ETH and ERC-20 balances for a Base address with USD values (via CoinGecko).
Inspect transactions, token metadata, gas metrics, contract details, and network stats from a single CLI.
Analyze token transfers in a given transaction and surface gas costs, L2/L1 breakdown, and USD equivalents for quick financial assessment.
Use cases include wallet portfolio checks, transaction auditing, contract investigation, whale monitoring, and real-time network health checks.

Quick Start

Run python3 ~/.hermes/skills/blockchain/base/scripts/base_client.py wallet <address> to fetch balances and USD valuations.

FAQPage Schema

How do I query Base blockchain wallet balances with USD pricing?▼

Query Base blockchain wallet balances with USD pricing by running a local Python CLI script that fetches ETH and ERC-20 token values via Base RPC and CoinGecko without API keys.

Can I inspect Base L2 transaction gas costs and token transfers without an API key?▼

Yes, you can inspect Base L2 transaction gas costs and token transfers without an API key using batched RPC calls to retrieve L2/L1 breakdowns and CoinGecko USD equivalents.

What is the best way to analyze Base network stats and whale activity locally?▼

Analyzing Base network stats and whale activity locally is done through a Python CLI that retrieves live network health metrics and on-chain data using key-free Base RPC calls.

Do I need an API key to retrieve ERC-20 token metadata and contract details from Base?▼

No API key is needed to retrieve ERC-20 token metadata and contract details from Base, as the CLI queries the Base RPC and CoinGecko API directly without key authentication.

How does batched RPC improve efficiency for querying Ethereum L2 on-chain data?▼

Batched RPC improves efficiency for querying Ethereum L2 on-chain data by combining multiple network requests into single calls, reducing latency when retrieving wallet balances and contract details.

Are there limitations to using CoinGecko and Base RPC for portfolio auditing?▼

Limitations of using CoinGecko and Base RPC for portfolio auditing include reliance on public API rate limits and the absence of authenticated endpoints for real-time high-frequency trading data.
