Flash loans are best understood as execution tools rather than traditional lending products. Their purpose is to provide immediate liquidity inside a single blockchain transaction.
In DeFi markets, opportunities such as arbitrage, liquidity routing, or collateral swaps can appear and disappear within seconds. Waiting to unlock capital can eliminate the opportunity entirely. Flash loans solve this by enabling capital access without long-term borrowing exposure.
The execution flow typically follows:
- Loan capital is released by a smart contract
- A financial action is executed
- Outcome is validated
- Loan and fee are repaid
- Transaction finalizes atomically
If repayment fails, the blockchain reverts the entire transaction.
Flash loans function as infrastructure for execution efficiency in decentralized finance.
