What Is the Impact of “Flash Loans” on the Stability of Liquidity Pools in DeFi?

Flash loans allow users to borrow uncollateralized assets instantly, provided the loan is repaid within the same transaction block. While not directly causing slippage, they enable large-scale, near-riskless arbitrage and manipulation, such as draining a liquidity pool or executing a massive trade that causes extreme, temporary price impact.

This sudden, massive liquidity removal or trade execution can lead to high slippage for other concurrent transactions, challenging the pool's stability.
