How Does a Centralized Exchange (CEX) Price Feed Differ in Risk from a DEX Feed?
A CEX price feed is determined by its internal order book and is generally more resistant to single-transaction manipulation than a low-liquidity DEX. However, a CEX feed is subject to counterparty risk, regulatory risk, and potential manipulation by the exchange itself.
A DEX price feed, while more susceptible to flash loan attacks, is transparent and decentralized, but only as robust as its pool liquidity.
