SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires cast, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a seamless way to query live Ethereum blockchain data directly from your local environment, eliminating the need for external RPC providers and simplifying blockchain data access.

Core Features & Use Cases

  • Read-Only Blockchain Queries: Access block information, balances, transaction details, gas prices, and more.
  • Multi-Network Support: Query various Ethereum networks (mainnet, testnets) installed within the Obol Stack.
  • Smart Contract Interaction: Perform read-only calls to smart contracts, including ERC-20 token queries and ERC-8004 agent identity lookups.
  • Use Case: Check the current gas price on the Ethereum mainnet or retrieve the ETH balance of a specific address.

Quick Start

Use the ethereum-networks skill to get the current gas price.

FAQPage Schema
How do I query Ethereum blockchain data like balances and gas prices locally?▼

This Skill queries Ethereum blockchain data through a local RPC gateway, allowing you to retrieve block numbers, balances, and gas prices using JSON-RPC methods.

Can I check ERC20 token balances and smart contract data without an external RPC provider?▼

Yes, you can perform read-only smart contract calls including ERC20 token balance queries and ERC-8004 agent identity lookups directly via the installed local networks without external providers.

Do I need the cast CLI tool to query ETH balances and transaction details?▼

Yes, the 'cast' CLI tool is required as a dependency to efficiently interact with the eRPC load balancer when querying ETH balances and transaction details locally.

What is the best way to access read-only JSON-RPC data across multiple Ethereum networks?▼

The best way to access read-only JSON-RPC data is by querying multiple Ethereum networks installed within the Obol Stack, supporting various methods for block numbers and transaction details.

Does querying Ethereum mainnet and testnets through a local RPC gateway support write operations?▼

No, querying Ethereum mainnet and testnets through this local RPC gateway is strictly limited to read-only operations and does not support write or transaction submission operations.
