# Oracles

The protocol publishes oracle data that integrating protocols can read. There are protocol-operated NAV feeds, AggregatorV3Interface wrappers over those feeds (delivered via Chainlink CRE / CCIP), a pull-based Data Stream for reUSD NAV, and an offchain reserves attestation feed:

## reUSD NAV oracle

Publishes the daily mint and redeem price for reUSD. Protocol-operated and not derived from secondary-market pricing. Automated writes to the oracle are performed by the Chainlink Runtime Environment (CRE) daily.

See the canonical [reUSD NAV oracle address list](/products/smart-contracts.md#reusd-nav-oracle) for deployed networks and explorer links, and [Oracle guardrails](/transparency-and-data-show-me-the-receipts/audits-attestations-custody-structure.md#oracle-guardrails) for the onchain limits that bound every update.

## 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                                                                                         |
| ----------------- | --------------------------------------------------------------------------------------------- |
| Stream ID         | `0x00072c74e4a28e4cb93cf0551e1bd992af743db37ce791d65cccadd7556f5c40`                          |
| 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.

See the canonical [reUSDe NAV oracle address list](/products/smart-contracts.md#reusde-nav-oracle) for deployed networks and explorer links.

## Chainlink CRE / CCIP oracles

AggregatorV3Interface wrappers over the protocol NAV oracles above, so integrators can read NAV through the usual Chainlink feed interface. They are not independent Chainlink price oracles: the value is Re's NAV, delivered via Chainlink Runtime Environment (CRE) or Chainlink CCIP. Each supported chain exposes an 18-decimal and an 8-decimal reader. Tempo has token deployment only; no wrapper yet.

The canonical wrapper address lists are maintained in Smart contracts:

* [reUSD CRE / CCIP oracle addresses](/products/smart-contracts.md#reusd-cre-and-ccip-oracles)
* [reUSDe CRE / CCIP oracle addresses](/products/smart-contracts.md#reusde-cre-and-ccip-oracles)

## Offchain reserves feed (Chainlink)

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

See the canonical [reserves feed and reader contract](/products/smart-contracts.md#reserves-attestation).
