Flash Loans
Borrow any amount with zero collateral — if you can't repay within the same transaction, the entire thing reverts as if it never happened. Used for arbitrage, liquidations, and collateral swaps.

Strategy Details
DEX Arbitrage: Borrow USDC → buy ETH on DEX A (cheaper) → sell ETH on DEX B (more expensive) → repay loan + fee → keep profit.
This only works when the price difference exceeds the flash loan fee (0.05%) + gas costs. MEV bots do this thousands of times per day.
