## Flash Loan Arbitrage Mechanics

Flash loan arbitrage mechanics involve the use of uncollateralized, instant loans to execute complex, multi-step trades within a single transaction block. Because the loan must be repaid within the same transaction, there is zero principal risk for the lender, provided the transaction succeeds.

This mechanism allows traders with minimal capital to exploit price discrepancies across different decentralized exchanges instantly. While this enhances market efficiency by closing price gaps, it also creates significant risks if the arbitrage strategy fails or if the transaction is front-run by malicious bots.

Flash loans have become a primary tool for both legitimate market participants and hackers seeking to manipulate protocol prices. Mastering these mechanics requires a deep understanding of blockchain transaction ordering and gas management.

It is a quintessential example of how programmable money creates new, high-speed financial instruments.
