## Flash Loan Risks

Flash loan risks arise from the unique ability to borrow massive amounts of capital without collateral, provided the loan is repaid within the same transaction block. While useful for arbitrage and refinancing, flash loans are frequently targeted by malicious actors to manipulate price oracles or exploit smart contract vulnerabilities.

If the transaction fails to repay the loan, the entire operation is reversed by the blockchain, protecting the protocol from loss. However, the sheer scale of capital that can be moved in a single block makes them a potent tool for adversarial activity.

Users must be aware that flash loans can be used to drain liquidity from vulnerable pools in seconds.

## Glossary

### [Flash Loans](https://term.greeks.live/area/flash-loans/)

Mechanism ⎊ Flash loans are uncollateralized loans in decentralized finance (DeFi) that must be borrowed and repaid within a single blockchain transaction.

### [Risk Management](https://term.greeks.live/area/risk-management/)

Analysis ⎊ Risk management within cryptocurrency, options, and derivatives necessitates a granular assessment of exposures, moving beyond traditional volatility measures to incorporate idiosyncratic risks inherent in digital asset markets.

### [Protocol Security](https://term.greeks.live/area/protocol-security/)

Protection ⎊ Protocol security refers to the defensive measures implemented within a decentralized derivatives platform to protect smart contracts from malicious attacks and unintended logic failures.

### [Smart Contract](https://term.greeks.live/area/smart-contract/)
