SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Security analysts, crypto researchers, and Web3 users often have to manually navigate multiple separate block explorers, switch between different chain-specific interfaces, and compile fragmented data to get a complete view of wallet activity, token metrics, or network conditions. This skill eliminates that friction by providing a single, unified read-only interface to 8 major EVM blockchains.

Core Features & Use Cases

  • Multi-chain wallet analysis: Check native and ERC-20 token balances across Ethereum, BNB Chain, Base, Arbitrum, Polygon, Optimism, Avalanche, and zkSync in a single call, or scan all 8 chains simultaneously for one address to get a full cross-chain portfolio with USD valuations.
  • Transaction and contract inspection: View full transaction details including fees and status, decode opaque transaction input data into human-readable function calls, and inspect smart contracts for proxy patterns, ERC standard compliance, and bytecode size.
  • Security and market insights: Detect dangerous unlimited ERC-20 token approvals, track large whale transfers exceeding a custom USD threshold, get real-time gas prices and cost estimates for common operations, resolve ENS names to addresses (and vice versa), and pull token metadata with market cap calculations. A common real-world use case: A security analyst can use this skill to quickly verify if a compromised user wallet has granted unlimited approval to a known malicious DEX contract, or compare gas costs across all 8 supported chains to recommend the cheapest option for a pending transaction.

Quick Start

Use the evm skill to retrieve the full cross-chain portfolio and all known ERC-20 token balances for the Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, including the total USD value of all holdings.

FAQPage Schema
How do I check wallet balances across multiple EVM chains at once?

To check wallet balances across multiple EVM chains, use a unified read-only query interface to scan Ethereum, BNB Chain, Base, Arbitrum, Polygon, Optimism, Avalanche, and zkSync simultaneously for native and ERC-20 token holdings with USD valuations.

Can I decode transaction input data and inspect smart contracts without paid API keys?

You can decode transaction input data and inspect smart contracts without paid API keys by using a tool that integrates public APIs for zero external dependency execution, decoding opaque inputs into human-readable function calls and detecting proxy patterns.

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

The best way to compare gas prices across EVM blockchains is to query real-time gas prices and cost estimates for common operations across 8 supported networks simultaneously, allowing you to identify the cheapest option for pending transactions.

How do I detect dangerous ERC-20 token approvals and whale transfers?

To detect dangerous ERC-20 token approvals and whale transfers, query wallet addresses for unlimited token approvals to known contracts and track large transfers exceeding a custom USD threshold across supported EVM networks.

Does cross-chain wallet analysis support ENS resolution and token market cap calculations?

Cross-chain wallet analysis supports ENS resolution by resolving names to addresses and vice versa, and performs token metadata extraction with market cap calculations using public API integration without requiring paid RPC keys.

What are the limitations of read-only EVM blockchain queries for security operations?

Read-only EVM blockchain queries for security operations are limited to retrieving existing data like transaction details, network statistics, and contract bytecode across 8 chains, meaning they cannot execute state-changing operations or interact with writable contract functions.
