Flash Loan Usage Explainer

WHAT IT DOES

This tool analyzes flash loan transactions and explains them in plain English. It reads transaction details including the flash loan protocol being used (Aave, dYdX, Uniswap, etc.), the loan amount and asset, callback function logic from bytecode, repayment conditions, profit generation mechanism, arbitrage or liquidation operations, collateral requirements (if any), fee structures, success conditions, risk of failure, estimated gas cost, and transaction flow and sequence. The AI layer translates these on-chain metrics into a clear, actionable explanation — describing what the loan does, how it generates profit, and the risks involved before you sign. This helps you understand complex flash loan transactions and avoid potentially malicious or unprofitable loans.

HOW TO USE

Connect your wallet, select the network, and paste the flash loan transaction hash you want to investigate. Select the protocol being used and enter the loan amount. The tool will analyze the transaction structure, decode the callback logic and profit mechanism, then display the results alongside an AI-generated plain-English explanation. No transaction is required — this is a read-only operation. The AI explanation is generated from the exact data the tool reads, ensuring the guidance is grounded in what the transaction actually shows.

TECHNICAL MECHANISM

The tool performs view calls to fetch transaction details and decodes the callback function logic from the bytecode. It identifies the flash loan protocol being used, the loan amount and asset, and traces the transaction flow to understand how the borrowed funds are used. The tool analyzes the profit generation mechanism — whether the loan is for arbitrage, liquidation, or other strategies — and evaluates the repayment conditions and fee structures. It calculates the risk of failure based on the complexity of the operation and the dependency on price movements. All calculations are performed against the current block state, and the AI prompt is constructed entirely from the actual read results — never from assumptions — ensuring the analysis is grounded solely in what the transaction actually shows. All reads are performed through the connected wallet's provider.

WHAT IT CANNOT SEE

This tool cannot definitively determine if a flash loan is safe or malicious — it only reads on-chain transaction structure and patterns. It cannot detect off-chain intent. It cannot verify the borrower's ability to complete the loan. It cannot predict price movement during execution. Calculations depend on state which may change before execution. It cannot detect hidden logic in unverified code. It cannot guarantee repayment success. Flash loans may fail due to price changes, gas issues, or reentrancy attacks. The AI explanation is generated from the data the tool reads and should be treated as informational, not as a guarantee of safety.

PLEASE NOTE

EVM chains only. Explanations are AI-generated from data the app reads on-chain — always review what you are actually signing in your wallet before approving it. This tool is read-only and never initiates transactions.
