PRICE FEEDS FROM MEDIAN TO OSM TO SPOT Every collateral type in USDD has its own oracle module feeding prices to the Vat. Each module has three contracts working in sequence: Median, OSM and Spot. The Median computes a price from a list of supported feeds. The OSM then updates the current and next price from that value, and the Spot reads the current price to update the Vat. WHY THE DELAY LAYER MATTERS The OSM keeps new prices from being used until a set delay has passed, with the default time between updates at one hour. Chainlink and WinkLink Data Feeds serve as the primary oracles. ✅ Median computes a price from whitelisted feeds ✅ OSM holds the next price until the delay passes ✅ Spot updates the collateral price in the Vat ✅ Chainlink and WinkLink Data Feeds are the primary oracles Layered price checks give Vault safety a strong footing as new collateral types arrive. @justinsuntron @usddio_cn #TRONEcoStar
