What are the software requirements for using this skill?

You need to have Foundry's 'cast' utility installed on your system to fetch the on-chain data.

Do I need a private RPC URL to check gas prices?

No, while custom RPCs can be used, the skill includes fallback support for PublicNode RPCs to ensure it works out of the box.

Which blockchain networks are supported by this skill?

The skill supports Ethereum, Polygon (Matic), Arbitrum, Optimism, Base, and Binance Smart Chain (BSC).

Can I use this skill to check fees on Solana?

No, this skill is specifically for EVM chains. For Solana, you should use the dedicated 'sol-fees' skill.

分析と監視

Fetches real-time gas prices across multiple EVM-compatible blockchain networks including Ethereum, Polygon, and Arbitrum.

The EVM Gas Price Tracker skill enables developers to instantly monitor current transaction costs across major Ethereum Virtual Machine (EVM) chains directly within Claude Code. By leveraging Foundry's 'cast' utility and public RPC nodes, it provides live fee data for Ethereum, Polygon, Arbitrum, Optimism, Base, and BSC. This tool is essential for Web3 developers looking to optimize transaction timing, manage deployment costs, and monitor network congestion without leaving their terminal environment.
