The Flash Loan Attack Framework

Before your auditor does, simulate flash loan attacks against every public function in your protocol. Here is the framework we use for all DeFi protocol security reviews. A flash loan gives an attacker $1B+ for one transaction at near-zero cost. The question for every DeFi protocol function: If an attacker could borrow...

  • If an attacker could borrow $1B and do anything in a single transaction, what could they do to this protocol?

Flash Loan Attack Simulator

// Test contract: simulate flash loan attack scenarios contract FlashLoanAttackSimulator is IFlashLoanReceiver { ILendingPool public aavePool; // Attack scenario 1: Oracle manipulation via large spot trade function simulateOracleManipulation( address targetProtocol, address oracleToken, uint256 flashLoanAmount ) extern...

    Attack Scenarios to Test for Every Protocol

    Scenario 1: Oracle price manipulation Can an attacker use flash loan capital to move the spot price used as an oracle, then exploit the manipulated price? Defense check: Does your oracle use TWAP? Is the TWAP period long enough to be manipulation-resistant at your TVL? Scenario 2: Governance voting manipulation Can an...

      Frequently asked questions

      Every DeFi protocol that: holds user funds as collateral, uses on-chain price data for any calculation, has governance voting, or executes trades within protocol logic. If your protocol fits any of these criteria — simulate flash loan attacks before your external audit begins.
