# Flash Loan Attacks ⎊ Area ⎊ Resource 20

## What is the Exploit of Flash Loan Attacks?

These attacks leverage the atomic nature of blockchain transactions to borrow a substantial, uncollateralized loan and execute a series of trades to manipulate an asset's price on one venue before repaying the loan on the same block. The profitability hinges on the successful execution of this multi-step manipulation within a single, indivisible transaction context. Such events expose vulnerabilities in oracle price feeds or Automated Market Maker (AMM) curves.

## What is the Arbitrage of Flash Loan Attacks?

The core mechanism often involves exploiting temporary price discrepancies across different decentralized exchanges or between spot and derivatives markets created by the attacker's initial capital injection. Successful execution requires precise calculation of the required capital, the market impact of the trades, and the resulting profit margin after repaying the principal and fees. This is a form of high-speed, on-chain market microstructure arbitrage.

## What is the Transaction of Flash Loan Attacks?

The entire sequence, from loan origination to repayment, is encapsulated within one on-chain transaction, which is the defining characteristic of this risk. This atomicity prevents external actors from intervening mid-process, making the attack deterministic if the logic is sound. Monitoring for unusually large, self-canceling transaction flows is a key detection strategy.
