## Flash Loan Composability

Flash loan composability refers to the ability to combine multiple DeFi protocols into a single atomic transaction facilitated by a flash loan. Because flash loans require no collateral, they allow users to interact with lending pools, decentralized exchanges, and yield aggregators simultaneously.

If any part of the transaction fails, the entire sequence is reverted, protecting the user from partial execution risks. This feature is highly beneficial for arbitrageurs who can exploit price discrepancies across different platforms without risking their own capital.

However, this same composability allows attackers to chain complex interactions that bypass security checks or drain liquidity pools. It effectively lowers the barrier to entry for executing sophisticated financial maneuvers that were previously only available to institutional market makers.

The atomic nature of these operations is a fundamental property of smart contract-based finance.
