📌 Key Considerations

⚡ Atomic Execution: Flash loans execute within a single block — either the entire transaction succeeds, or it's fully reverted (no partial execution).

💰 No Collateral Required: Because the loan is borrowed and repaid in the same transaction, no upfront collateral is needed.

🛡️ Security Risk: Re-entrancy attacks, oracle manipulation, and contract vulnerabilities are the biggest risks in real flash loan execution.

🧪 Test First: Always test flash loan strategies on forked mainnet (Hardhat/Foundry) before any live deployment.
