Time-Weighted Average Price Oracles
Time-Weighted Average Price Oracles provide a price feed based on the average price of an asset over a specified period. This smoothing effect makes it significantly harder for an attacker to manipulate the price using a single large transaction, as the average is resistant to short-term spikes.
It is a standard industry practice for protocols that require robust, manipulation-resistant price data. While they provide better security against flash loans, they are less responsive to sudden, legitimate market crashes.
Finding the right balance between responsiveness and security is a major design challenge for protocol architects. It is a foundational component of modern DeFi security.
