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 use complex web interfaces to track wallet portfolios, gas prices, and contract security across eight different EVM-compatible blockchains.

Core Features & Use Cases

  • Multi-Chain Portfolio Tracking: Instantly view native balances and ERC-20 token holdings across Ethereum, BNB Chain, Base, Arbitrum, Polygon, Optimism, Avalanche, and zkSync.
  • Security & Inspection: Detect dangerous token approvals and inspect smart contract standards or proxy implementations before interacting with them.
  • Use Case: A user wants to compare gas fees across all supported chains to find the cheapest network for a transaction or check if a specific wallet address has granted unlimited token approvals to a malicious contract.

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-compatible blockchains?▼

To check wallet balances across EVM-compatible blockchains, query the wallet address to instantly retrieve native balances and ERC-20 token holdings across eight networks including Ethereum, Arbitrum, and Polygon.

What is the best way to find dangerous token approvals before interacting with a smart contract?▼

The best way to detect dangerous token approvals is by running a security inspection on the contract address, which identifies unlimited token approvals and potential vulnerabilities before you interact with it.

How do I compare gas prices across different crypto networks to find the cheapest transaction fees?▼

To compare gas prices across crypto networks, query real-time blockchain data across the eight supported EVM-compatible networks to evaluate current gas fees and find the cheapest network for your transaction.

Does this blockchain security analysis tool require external dependencies or API keys?▼

This blockchain security analysis tool requires zero external dependencies, operating entirely on standard-library-only execution to query blockchain data and perform contract inspections without additional setup.

Can I inspect proxy implementations and smart contract standards on the BNB Chain?▼

Yes, you can inspect proxy implementations and verify smart contract standards on BNB Chain, as the tool supports security auditing and standard inspection across all eight EVM-compatible networks.
