Understanding Flash Loan Arbitrage
Flash loan arbitrage is a unique and sophisticated method in the DeFi (Decentralized Finance) space that involves borrowing and repaying a loan without collateral within the same transaction. The primary goal is to exploit price differences across various decentralized exchanges (DEXs) to make a profit.
What is Flash Loan Arbitrage?
At its core, flash loan arbitrage takes advantage of price discrepancies between different DEXs. Here’s how it typically works:
Borrowing: A flash loan allows you to borrow an amount of cryptocurrency from a lending protocol without providing collateral. The borrowed amount is used to purchase tokens at a lower price on one exchange.
Trading: Immediately, you sell these tokens on another exchange where the price is higher.
Repayment: Finally, you repay the borrowed amount and any fees, pocketing the difference as profit.
The Mechanics of Flash Loans
Flash loans are facilitated by smart contracts on blockchain networks. Here’s a closer look at how they operate:
