# Oracles

The protocol publishes oracle data that integrating protocols can read. There are three onchain feeds, plus a pull-based Data Stream that delivers the same reUSD NAV via a DON-signed report:

## reUSD NAV oracle

Publishes the daily mint and redeem price for reUSD. Protocol-operated, updated daily at 00:00 UTC, and not derived from secondary-market pricing.

| Chain     | Oracle contract                                | Read contract                                                                                                                                                     |

## reUSD redemption rate stream (Chainlink Data Streams)

The reUSD NAV is also available as a Chainlink Data Stream: a pull-based, DON-signed report (schema v7, Exchange Rate) that integrators can fetch via the Data Streams API and verify onchain on supported chains.

| Field             | Value                                                                                         |
| ----------------- | --------------------------------------------------------------------------------------------- |

| Report schema     | v7 (Exchange Rate)                                                                            |
| Source            | reUSD NAV oracle (daily mint/redeem price, not secondary-market pricing)                      |
| Access            | Chainlink Data Streams API (allowlisted); reports verified onchain via the Chainlink Verifier |
| Chainlink catalog | <https://data.chain.link/streams/reusd-usd-exchangerate-streams>                              |
| Reference         | <https://docs.chain.link/data-streams>                                                        |

The stream ID is the canonical identifier consumers use to subscribe to and verify reports. It is chain-agnostic, not a contract address, and there is no onchain account that "is" the stream. Chainlink's DON sources the rate from the protocol's NAV oracle, signs reports against this stream ID, and serves them offchain. Any allowlisted integrator can pull those reports and verify them onchain via the Chainlink Verifier on their target chain.

## reUSDe NAV oracle

Publishes the daily mint and redeem price for reUSDe, on the same daily cadence.

| Chain    | Oracle contract                              | Read contract                                                                          |

## Offchain reserves feed (Chainlink)

Aggregate offchain reserve and §114 trust account balances, attested daily by The Network Firm and published onchain via Chainlink.
