Etherscan Introduces Transaction Debugger for Enhanced Ethereum Transaction Analysis

Etherscan has unveiled its new Transaction Debugger skill, aimed at transforming complex Ethereum transactions into easily digestible reports. This tool is specifically designed for AI agents like Claude Code and Codex, allowing them to analyze Ethereum Virtual Machine (EVM) transactions using live data directly from Etherscan.

Functionality of the Transaction Debugger

The Transaction Debugger decodes the calls within a transaction, outlining the execution path taken. It tracks changes to assets and permissions, detailing who received what and which contracts were granted the authority to spend tokens. In cases of transaction failures, the skill provides failure analysis to assist users in understanding the issues.

According to Etherscan, the output includes a transaction summary, execution flow, and security observations, with report modes ranging from Simple to Security. Each report features direct links to Etherscan, ensuring that users can verify the information through the explorer.

Integration and Additional Tools

The Transaction Debugger can analyze individual transactions or compare two side by side and is compatible with any EVM chain supported by Etherscan. This tool is part of Etherscan's broader Build with AI initiative, which began in August 2026. The public promotion of the debugger started on September 4, 2026, with further guidance provided on October 16, 2026.

Etherscan's MCP server offers structured, read-only access to on-chain data across more than 60 EVM-compatible chains. The company emphasizes the importance of pairing the debugger with its CLI or MCP server to ensure smooth data retrieval. Additionally, two companion skills, Etherscan Flow and Contract Review, complement the debugger's functionality.

Importance of Accurate Data

Etherscan has highlighted that the outputs from the debugger are sourced directly from its API, mitigating the risk of inaccurate or
