## Flash Loan Exploit

A flash loan exploit is a sophisticated attack that uses a massive, uncollateralized loan to manipulate the price of an asset on a decentralized exchange, which then triggers a vulnerability in another protocol. Because flash loans allow a user to borrow vast amounts of capital for a single transaction block, they can be used to move markets in ways that would otherwise require significant personal wealth.

The attacker uses the temporary price distortion to extract value from a target protocol, such as through incorrect liquidation or oracle manipulation, and then repays the loan instantly. This type of exploit is a major concern for derivatives platforms that rely on on-chain liquidity for pricing.

Defending against such attacks requires robust oracle designs and mechanisms that prevent price manipulation within a single block.
