SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This skill eliminates the need to manually navigate multiple block explorers or price trackers by providing a unified, command-line interface for querying data across eight major EVM-compatible blockchains.

Core Features & Use Cases

  • Multi-Chain Portfolio Tracking: Instantly view native balances and ERC-20 token holdings across Ethereum, Base, Arbitrum, and more.
  • Security & Inspection: Detect dangerous token approvals and inspect smart contract bytecode to identify potential risks before interacting with them.
  • Use Case: A user wants to compare gas fees across multiple networks to find the cheapest chain for a transaction or needs to quickly decode a transaction hash to understand what a contract interaction actually performed.

Quick Start

Use the evm skill to check the portfolio balance and token holdings for the wallet address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on the Ethereum network.

FAQPage Schema
How do I check wallet balances and token holdings across multiple EVM blockchains?

To check wallet balances and token holdings across multiple EVM blockchains, you can query native balances and ERC-20 token metadata using standard Python scripts interfacing with public RPC endpoints across eight networks like Ethereum and Arbitrum.

Can I compare gas prices across different EVM-compatible networks before executing a transaction?

Yes, you can compare gas prices across different EVM-compatible networks by querying real-time blockchain data from public decentralized APIs, allowing you to find the cheapest chain for optimized transaction execution.

How do I audit a smart contract for dangerous token approvals and inspect bytecode?

To audit a smart contract for dangerous token approvals and inspect bytecode, you query the contract's metadata and transaction history via decentralized data APIs to identify potential security risks before interacting.

Does this EVM data tool require any external dependencies or API keys to function?

No external dependencies or API keys are required, as the tool operates using standard library Python scripts to interface directly with public RPC endpoints and decentralized data APIs across EVM networks.

How do I decode a transaction hash to understand what a smart contract interaction actually performed?

To decode a transaction hash and understand a smart contract interaction, you query the transaction history across the EVM-compatible network to inspect the executed bytecode and contract metadata.

What is the best way to view real-time portfolio data across Ethereum, Base, and Arbitrum?

The best way to view real-time portfolio data across Ethereum, Base, and Arbitrum is using a unified command-line interface that queries native balances and ERC-20 token holdings across the eight supported EVM-compatible blockchains.
