SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

It removes the need to manually inspect EVM blockchains for balances, token details, gas prices, transaction history, and contract behavior across multiple networks.

Core Features & Use Cases

  • Wallet and Portfolio Lookup: Check native balances and ERC-20 holdings for a single address, including multi-chain scans for the same wallet.
  • Network and Gas Intelligence: Compare gas prices, native token prices, block stats, and transaction fees across major EVM chains.
  • Transaction and Contract Analysis: Inspect transactions, decode calldata, resolve ENS names, review approvals, detect whale transfers, and identify contract standards or proxies.
  • Use Case: A trader can quickly compare fees before a swap, verify a token contract, and review risky approvals without switching tools.

Quick Start

Ask for an EVM wallet, token, transaction, ENS, or gas check on the chain you care about, and the skill will return the blockchain details in a structured summary.

Frequently Asked Questions about evm

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

FAQPage Schema
How do I check an EVM wallet balance and token holdings across multiple chains?▼

To check an EVM wallet balance, you retrieve native balances and ERC-20 holdings for a single address. The skill performs multi-chain scans across Ethereum, BNB Chain, Base, Arbitrum, Polygon, Optimism, Avalanche, and zkSync.

Can I compare gas prices and transaction fees across different EVM blockchains?▼

Yes, you can compare gas prices across different EVM blockchains. The skill retrieves network intelligence, comparing current gas prices, native token prices, block stats, and transaction fees across major EVM chains.

How do I decode transaction calldata and resolve an ENS name for a contract?▼

To decode transaction calldata and resolve an ENS name, you inspect transactions using public ENS and 4byte APIs. This allows you to review contract behavior, identify proxy standards, and resolve addresses to readable names.

Does this EVM portfolio checker require any external dependencies or API keys?▼

This EVM portfolio checker requires JSON-RPC access and uses public CoinGecko, ENS, and 4byte APIs. It operates strictly in a read-only format and runs using only the Python standard library without external dependencies.

What is the best way to detect whale transfers and review risky token approvals?▼

The best way to detect whale transfers and review risky token approvals is through read-only transaction and contract analysis. The skill inspects transaction history, decodes calldata, and identifies contract standards to flag large transfers and approvals.
