Flash loans are uncollateralized loans that must be borrowed and repaid within the same transaction block. They enable complex DeFi strategies like arbitrage, liquidations, and collateral swaps without requiring initial capital.
Example
💡Example
A trader uses a flash loan to borrow 1000 ETH, arbitrage price differences between exchanges, and repay the loan plus fees - all in one transaction.

Common Questions
What happens if I can't repay a flash loan?
The entire transaction reverts, meaning you get your original funds back but pay gas fees for the failed transaction.
