SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Retrieve cross-chain EVM data (wallets, tokens, and gas) from multiple networks without API keys, enabling quick insights into on-chain activity.

Core Features & Use Cases

  • Cross-chain data access: query wallets, token balances, transactions, gas metrics, and ENS lookups across 8 chains.
  • No-key operation: operates with public RPCs and Python stdlib, reducing setup friction.
  • Use Case: Compare a wallet across Ethereum, Base, Arbitrum, Polygon, Optimism, BSC, Avalanche, and zkSync Era to assess activity and asset exposure.

Quick Start

Run the evm CLI to fetch wallet balances, token data, and gas stats across the 8 supported EVM chains.

Frequently Asked Questions about evm

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

FAQPage Schema
How do I check a wallet balance across multiple EVM chains without an API key?▼

You can check a wallet balance across 8 EVM chains without an API key by using a zero-dependency Python CLI that queries public RPC endpoints. It retrieves cross-chain wallet balances, token data, and gas metrics directly.

What EVM networks are supported for cross-chain data retrieval?▼

The supported EVM networks for cross-chain data retrieval include Ethereum, Base, Arbitrum, Polygon, Optimism, BSC, Avalanche, and zkSync Era. You can query wallets, tokens, and gas metrics across these eight chains.

Can I resolve ENS names and decode transactions using public RPC endpoints?▼

Yes, you can resolve ENS names and decode transactions using public RPC endpoints via batch JSON-RPC calls. The CLI fetches this EVM data directly without requiring external API keys or dependencies.

Do I need to install external Python packages to query on-chain token metadata?▼

No, you do not need to install external Python packages to query on-chain token metadata. The CLI uses Python 3.8+ standard library to fetch token balances and metadata across 8 EVM networks.

What is the best way to compare gas metrics across different EVM blockchains?▼

The best way to compare gas metrics across different EVM blockchains is using a zero-dependency Python CLI that queries public RPC endpoints. It fetches gas stats and built-in price lookups across 8 chains.

What are the limitations of using public RPC endpoints for cross-chain EVM data?▼

A limitation of using public RPC endpoints for cross-chain EVM data is potential rate limiting or downtime. The CLI operates read-only without API keys, so it may face restrictions on high-volume batch JSON-RPC calls.
