🗒️ DeFi｜Flash Loans
· Key points: The borrowed funds, plus fees, must be repaid to the liquidity pool before the transaction ends; otherwise, the entire transaction is void, as if it never happened.
· Why: Flash loans are not a vulnerability in themselves; in attacks, they are simply used to amplify the amount of capital involved. The real issue usually lies in the targeted protocol’s price source or contract logic.
· Practical tip: When evaluating a protocol, pay attention to where its prices come from. Protocols that rely solely on the instantaneous price of a single DEX pool are vulnerable to flash-loan attacks.
