# Oracle System

> Pyth PriceUpdateV2 with feed id, staleness, and confidence checks.

Every risk-sensitive instruction takes a Pyth `PriceUpdateV2` per priced mint.

Checks in `oracle/pyth.rs`:

* Account owner is the Pyth receiver program
* Feed id matches `AssetConfig.price_feed_id`
* Price `> 0`
* Age ≤ `max_price_age_secs`
* Confidence ≤ `max_confidence_bps` of the price

| Symbol                 | Feed role                                                                        |

| SOL / USDC             | Crypto USD                                                                       |
| TSLAx / GOOGLx / AAPLx | xStock / equity USD                                                              |
| ANTHROPIC / OPENAI     | Configured feed ids in the app (PreStocks have no canonical public equity print) |

On the Surfpool fork, Hermes may be unavailable. The app can refresh fork prices via cheatcode so health still moves. That is **demo infrastructure**, not a mainnet oracle design.

Stale or wide-confidence updates abort. The program does not "use the last good price" on a failed feed.
