How Do Decentralized Exchanges Mitigate the Risk of Single-Exchange Price Manipulation?
Decentralized exchanges (DEXs) mitigate the risk of single-exchange price manipulation by using oracles that aggregate data from multiple, high-liquidity exchanges. By calculating a Time-Weighted Average Price (TWAP) across numerous sources, they ensure that a temporary price spike on one low-volume exchange does not affect the final price feed.
This multi-source aggregation makes it prohibitively expensive for an attacker to manipulate the price across all necessary venues simultaneously.
