What software dependencies are required for this plugin?

You must have the Foundry toolkit (specifically the 'cast' command-line tool) installed on your local system.

Does this skill support Solana or non-EVM chains?

No, this skill is strictly for EVM-compatible chains. For Solana-specific data, you should use the 'sol-slot-info' skill.

Can I fetch specific historical blocks or just the latest one?

You can fetch any block by providing a specific block number, a hex value, or standard tags like 'finalized' or 'safe'.

Which chains are supported by the EVM Block Info skill?

It currently supports Ethereum (Mainnet), Polygon (Matic), Arbitrum, Optimism, Base, and Binance Smart Chain (BSC).

Do I need to provide my own RPC URL to use this skill?

No, while custom RPCs can be used, the skill includes a built-in fallback to PublicNode for immediate use.

Analytics & Monitoring

Retrieves detailed block information and metadata from various EVM-compatible blockchain networks.

About

The EVM Block Info Fetcher is a specialized Claude Code skill designed for blockchain developers and analysts to query real-time block data directly within their terminal environment. By leveraging the Foundry 'cast' tool, it provides instant access to block numbers, timestamps, gas usage, and transaction counts across major networks like Ethereum, Polygon, Arbitrum, Base, and BSC. This skill is essential for debugging smart contract deployments, verifying network status, and auditing on-chain activity without needing to navigate manual block explorers.

Key Features

Automated fallback to public RPC nodes for seamless connectivity without configuration
Real-time retrieval of latest, pending, or specific historical block numbers
2 GitHub stars
Multi-chain support for Ethereum, Polygon, Arbitrum, Optimism, Base, and BSC
Integration with Foundry's cast utility for high-performance blockchain queries
Support for block tags including latest, pending, earliest, finalized, and safe

Use Cases

Monitoring the current block height across multiple EVM chains for synchronization checks
Verifying the success and timestamp of a specific block after a smart contract transaction
Extracting block metadata and gas data for debugging on-chain events and performance
