Reading Onchain Data

What problem does it solve?

This Skill solves the challenge of efficiently reading historical and real-time blockchain data, which is often inefficient or impossible through direct RPC calls due to limitations in iteration, state access, and query capabilities.

Core Features & Use Cases

• Event-Driven Data Retrieval: Leverages smart contract events (logs) as the primary mechanism for accessing historical data.
• Tool Selection Guidance: Provides clear recommendations on when to use The Graph, Dune Analytics, or Multicall3 based on specific use cases like dApp backends, analytics, or batched reads.
• RPC Limitation Awareness: Educates users on the constraints of RPC endpoints, including rate limits, historical state access, and eth_getLogs range limitations.
• Use Case: An AI agent needs to track the total supply of a token over time. This Skill guides the agent to use an appropriate indexing solution like The Graph or Dune, rather than attempting inefficient RPC calls.

Quick Start

Use the indexing skill to find all USDC transfer events between block 19000000 and 19000100.
