A flash loan is an uncollateralized loan in decentralized finance (DeFi) that must be borrowed and repaid within a single transaction block. These loans allow users to borrow assets without any upfront collateral, provided that the borrowed amount is returned before the transaction ends. Flash loans are often used for arbitrage opportunities, debt refinancing, or executing complex strategies in DeFi, where the user can make a profit. However, they also carry risks, such as the possibility of liquidation or manipulation if used maliciously.
