txSync’s Paymaster operations are enabled by a custom oracle provided by DIA, delivering robust, real-time asset price feeds for the STORJ token.
Additionally, txSync leverages a custom DIA oracle for real-time USDC pricing, enabling users to pay gas fees with USDC on txPortal and txBridge, enhancing transaction convenience.
This oracle utilizes a high-frequency, 120-second data aggregation window and fetches data from a curated list of high-volume exchanges. You can view the feed’s data sources in real-time on the DIA APP, by visiting the corresponding asset’s detail page.
The asset’s price calculation employs the Moving Average Price with Interquartile Range (MAIR) methodology. For an in-depth explanation of the pricing mechanisms, consult DIA's Technical Documentation.
The smart contract for this oracle employs a deviation-based update mechanism with a 5% threshold for tokens STORJ and ETH and 1% for USDC. Any price change greater than this value triggers an immediate on-chain update.
Additionally, the price feeds update every 24 hours if there are no deviation-based updates.
