Flash Loan Arbitrage Dynamics

Flash loan arbitrage dynamics involve the use of uncollateralized, instant loans to execute arbitrage trades that would otherwise be impossible due to capital constraints. A flash loan allows a trader to borrow a large amount of assets, perform a trade, and repay the loan within a single transaction block.

If the trade is not profitable, the transaction fails and is reverted, ensuring no risk to the lender. This mechanism democratizes access to arbitrage, allowing anyone with the technical knowledge to participate.

In the context of stablecoins, flash loans can be used to quickly close large price gaps and restore the peg. However, they can also be used to manipulate prices or drain liquidity, making them a double-edged sword for protocol stability.
