SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Convert raw blockchain transaction data and logs into concise, plain-English explanations so investigators, analysts, and curious users can quickly understand what happened without parsing low-level data.

Core Features & Use Cases

  • Structured Parsing: Extract hash, from/to addresses, value, token transfers, gas metrics, method signatures, events, block number, and timestamp.
  • Classification & Context: Classify transactions as transfers, swaps, mints, burns, staking, governance, NFT actions, contract deployments, or multisig flows and assess direction and complexity.
  • Flow Tracing & Reporting: Map fund routing through contracts, DEXes, bridges, and aggregators and produce a step-by-step plain-English report with token movement tables, gas cost breakdown, and notable observations such as potential MEV or mixer interactions.
  • Use Case: Forensic analysis of a suspicious wallet, audit of a complex DeFi swap transaction, or preparing an explanatory summary of contract interactions for non-technical stakeholders.

Quick Start

Analyze the provided raw transaction data or transaction hash and produce a plain-English transaction analysis with flow mapping, token movements, gas costs, and any uncertainty notes.

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

FAQPage Schema
How do I convert raw blockchain transaction data into a readable report?

To convert raw blockchain transaction data into a readable report, you can supply the raw payload or decoded logs to an analyzer. It parses the inputs and outputs a plain-English summary detailing token transfers, gas costs, and contract interactions.

Can I trace token flows and wallet activity without directly querying a blockchain node?

Yes, you can trace token flows and wallet activity without querying a blockchain node by providing raw transaction data or hashes to an analysis tool. It maps fund routing through contracts and DEXes while noting any incomplete data in the final report.

What's the best way to classify complex DeFi swap transactions for non-technical stakeholders?

The best way to classify complex DeFi swap transactions for non-technical stakeholders is to use a transaction analyzer that categorizes transactions into types like swaps or mints, then generates a step-by-step plain-English summary with token movement tables.

Does transaction analysis work with smart contract interactions across all EVM-compatible chains?

Transaction analysis works with smart contract interactions across EVM-compatible and similar chains when you supply the data. The tool decodes logs and classifies events like staking or governance actions for forensic analysis and reporting.

What should I do if my transaction hash lookup leaves some wallet tracing data incomplete?

If your transaction hash lookup leaves wallet tracing data incomplete, the analysis report will explicitly note any uncertain or missing data. Since the tool does not query external APIs, it relies entirely on the supplied payload and flags informational gaps.

Can I detect potential MEV or mixer interactions from decoded contract logs?

Yes, you can detect potential MEV or mixer interactions from decoded contract logs by analyzing the transaction flow. The analyzer maps fund routing through aggregators and bridges, highlighting notable observations like suspicious mixer interactions in the final report.
