To meet these requirements, zkDX has developed a hybrid oracle architecture that ensures real-time and accurate prices while avoiding potential attacks. The hybrid oracle utilized by zkDX combines the strengths of Chainlink, Pyth, and other well-established price oracles, alongside a self-feeding price system. This approach enables zkDX to cover both widely traded assets and long-tail assets. For trading products with sufficient liquidity, zkDX leverages Chainlink and Pyth to provide technical support and obtain reliable intermediate prices, ensuring the accuracy of trading. Regarding long-tail assets with lower liquidity, zkDX relies on price nodes which is a combination of the oracle price, and the average price from several major DEXs or CEXs of the trading assets to determine the most precise matching price. This approach facilitates close monitoring of prices, and if the price deviates by more than 0.5%, the node is excluded from the average calculation. As a result, even in extreme situations, any potential loss is controlled within a limited range. By leveraging the zkDX hybrid oracle solution, users can have utmost confidence in their trading activities and the security of their assets. This architecture guarantees real-time and accurate pricing, enabling seamless execution of limit orders and stop-loss orders, and delivering a user experience comparable to the major CEXs. --- # Agent Instructions This documentation is published with GitBook.
