DIA

Meridian Finance's USDM stablecoin is powered by a custom price oracle provided by DIA, designed for robust, real-time asset pricing.

Data Sourcing

This oracle utilizes a high-frequency, 120-second data aggregation window and fetches data from a curated list of over 20 exchanges. You can view the feed’s data sources in real time on the DIA APP.

Pricing Methodology

The 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.

Update Mechanism

The smart contract for this oracle employs a deviation-based update mechanism with a 0.5% threshold. Any price change greater than this value triggers an immediate on-chain update.

To view the oracle’s most up-to-date configuration, always refer to the DIA Forum, under Custom Delivery Request CDR #058
