Flash Loan Attack Pattern Explainer

WHAT IT DOES

Flash Loan Attack Pattern Explainer provides AI-powered analysis of transaction sequences that may involve flash loans or complex DeFi interactions. Analyze flash loan borrowing patterns including source protocol and borrowed amount. Examine the sequence of operations — swaps, price oracle queries, protocol interactions, and loan repayment timing. Detect known attack patterns including price oracle manipulation, reentrancy attacks, sandwich attacks, liquidation exploits, and governance attacks. Analyze token transfer patterns to identify unusual flow of assets. Examine price oracle data to detect manipulation attempts. Review swap events and liquidity pool balance changes to identify price impact patterns. Analyze transaction traces and protocol execution timelines to detect suspicious ordering of operations. The AI translates these technical findings into a plain-language verdict — Known Attack Pattern, Suspicious Sequence, Arbitrage Pattern, or Legitimate Interaction — with specific flags, timing details, and risk assessment.

HOW TO USE

1. Connect your Web3 wallet (Ethereum, Polygon, Arbitrum, Optimism, BSC, or any EVM-compatible chain).

2. Select the network that matches your target chain from the dropdown.

3. Paste the transaction hash you want to analyze.

4. Select analysis depth (standard or deep).

5. Click "analyze flash loan pattern" to read on-chain transaction data and generate an AI explanation.

6. Review the verdict, specific pattern flags, and risk assessment.

7. Make an informed decision about whether the transaction pattern is malicious or legitimate.

8. Remember: the AI explanation informs your decision, but your wallet's signature prompt is what actually protects you — always review it before signing.

TECHNICAL MECHANISM

Flash Loan Attack Pattern Explainer reads real on-chain transaction data including traces, logs, and state changes. The tool queries transaction receipts to extract the full sequence of calls, events, and state transitions. It identifies flash loan protocol interactions by scanning for known flash loan function signatures (e.g., flashLoan, executeOperation). It analyzes the sequence of operations to detect common attack patterns — borrowing, swapping, manipulating oracles, liquidating positions, and repaying. It tracks token transfer patterns through ERC-20 Transfer events to identify asset flows. It examines price oracle interactions by looking for oracle query calls (e.g., latestAnswer, getPrice). It identifies swap events from DEX protocols (Uniswap, Curve, Balancer). The parsed on-chain data is then passed to the AI bridge (BGAI.generate) which produces a structured verdict in plain language. The AI explanation is capped at 1,024 tokens and focuses on actionable flags and attack pattern identification.

WHAT IT CANNOT SEE

This tool cannot guarantee detection of all flash loan attack patterns — sophisticated attackers may use novel techniques not yet recognized. It cannot verify that an execution pattern will result in a profitable attack — many complex sequences are unsuccessful arbitrage attempts. It cannot detect attacks that use off-chain components or cross-chain flash loans. It cannot ensure that all known attack vectors are recognized. The AI analysis is based solely on on-chain transaction data — it cannot detect off-chain intent, future contract upgrades, or social engineering attacks. Always verify critical information independently and never rely solely on automated analysis for financial decisions. The AI explanation is generated and does not replace reviewing what you are actually signing in your wallet.

PLEASE NOTE

Flash Loan Attack Pattern Explainer supports EVM-compatible blockchains only (Ethereum Mainnet, Goerli, Polygon, Arbitrum One, Optimism, BNB Smart Chain, and others via network selection). The tool requires a free API key for the AI bridge. The tool never submits transactions or signs messages; it is strictly read-only. The AI explanation is generated after reading on-chain data — always review your wallet's signature prompt before approving any transaction. Pattern analysis does not guarantee an attack will succeed or that a sequence is necessarily malicious — some sequences may be complex arbitrage or legitimate interactions. Deep analysis may take longer but provides more thorough pattern detection. The tool relies on transaction trace data which may not be available for all networks or providers.
