SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Aggregates data from Etherscan, Dune Analytics, and other explorers to deliver a unified view of on-chain activity, enabling deeper address and contract investigations, market insights, and risk assessment.

Core Features & Use Cases

  • Address & transaction profiling: balance, activity patterns, token holdings, and contract interactions across supported chains.
  • Contract security & risk scoring: verify source, inspect ABI, assess vulnerabilities, and generate actionable recommendations.
  • Whale tracking & behavioral analytics: monitor large transfers, wallet labels, and protocol interactions to identify signal events.

Quick Start

Provide an Ethereum address to analyze and receive balance, recent transactions, and contract verification status.

Frequently Asked Questions about onchain-data-analysis

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I analyze Ethereum address activity and transaction history using on-chain data?▼

To analyze Ethereum on-chain data, aggregate address balances, transaction traces, and contract interactions from explorers like Etherscan. This provides a cohesive view of wallet activity patterns, token holdings, and gas usage across compatible networks.

What is the best way to track whale movements and large token transfers on-chain?▼

Tracking whale movements on-chain involves monitoring large transfers and wallet labels across protocols. By aggregating data from sources like Dune Analytics, you can identify behavioral signals and significant market events from large wallet interactions.

Can I assess smart contract security and risk using Etherscan and Dune Analytics data?▼

Yes, smart contract risk assessment is possible by verifying source code and inspecting ABIs from Etherscan. Aggregating this on-chain data generates actionable recommendations regarding contract vulnerabilities and security scoring.

Do I need API access to perform on-chain data analysis for address profiling?▼

Yes, performing on-chain data analysis for address profiling requires API access prerequisites. You must configure parameters like address, tx_hash, query_type, and chain to enable composable scripting and parameter customization.

Does this on-chain analysis approach work with multiple blockchain networks or just Ethereum?▼

This on-chain analysis approach is applied to Ethereum and compatible networks. By customizing the chain parameter, you can aggregate transaction tracing and contract verification data across different supported explorers.
