Etherscan Unveils Etherscan Flow for Simplified On-Chain Investigations

Etherscan has released a new tool called Etherscan Flow that simplifies transaction mapping and tracing for on-chain investigations. This tool is part of the company's Build with AI suite and allows AI agents and coding assistants to trace, verify, and visualize on-chain money flows across more than 60 EVM-compatible chains.

The RedSonic Vault exploit, which occurred around September 5, 2026, was a real-world stress test for the tool. Security researchers used Flow to map out exactly how the attacker used a flash loan to drain approximately 9.25 ETH, worth roughly $23,000, in a single transaction.

Flow works by querying Etherscan's live API data and generating a 'Flow Case' file, which is a structured output that can be imported into etherscan.io/flow for visual examination. This eliminates the need to manually hop between block explorers, contract calls, and wallet addresses to piece together what happened in a complex transaction.

The tool is designed to plug directly into AI agent workflows, allowing developers building investigation tools, compliance bots, or security monitors to integrate Flow's capabilities without rebuilding Etherscan's entire data pipeline from scratch. This could potentially democratize access to on-chain analytics for DeFi security.
