SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Read-only EVM client: Query wallet balances, token data, gas across 8 chains in a single, zero-dependency tool, reducing manual cross-chain research and context-switching.

Core Features & Use Cases

  • Wallet portfolio: view native balances and common ERC-20 holdings across Ethereum, BNB Chain, Base, Arbitrum, Polygon, Optimism, Avalanche, and zkSync Era.
  • Token data & pricing: fetch contract metadata and USD price estimates for tokens across multiple chains.
  • Gas & activity insights: compare gas prices and estimate transaction costs across networks to optimize timing.

Quick Start

Ask the agent to query the wallet balances and token holdings for a given address across all 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 wallet balances across multiple EVM chains at once?▼

You can retrieve cross-chain wallet balances by querying a single address across supported EVM networks. The tool performs multi-chain RPC calls to fetch native balances and ERC-20 holdings, returning consolidated JSON-formatted portfolio data for developers and analysts.

What is the best way to compare gas prices across Ethereum-compatible networks?▼

Comparing gas prices across EVM networks requires querying RPC endpoints for current rates. A cross-chain CLI tool fetches gas prices and estimates transaction costs across eight supported chains, helping developers optimize transaction timing and reduce fees.

Can I fetch ERC-20 token metadata and USD prices across different blockchains?▼

Fetching ERC-20 token metadata and USD prices across blockchains involves querying contract data via RPC. The tool retrieves contract metadata and performs price lookups across EVM-compatible chains, unifying token data and pricing estimates in a single JSON output.

Do I need to install dependencies to query EVM blockchain data?▼

Querying EVM blockchain data does not require additional dependencies with this zero-dependency tool. It operates as a standalone read-only CLI, meaning you can retrieve wallet balances, token data, and gas insights without installing extra libraries or configuring complex environments.

How do I get a consolidated view of token holdings across Layer 2 networks?▼

Getting a consolidated view of token holdings across Layer 2 networks requires aggregating data from multiple RPCs. The tool unifies wallet balances and ERC-20 holdings from networks like Arbitrum, Optimism, Base, and zkSync Era into a single JSON output for cross-chain analysis.
