Oracles
This page talks about how Rezerve uses oracles to get pricefeeds of various assets
RZR adopts Dia Data as its primary data layer.
We integrate DIA at three distinct tiers:
Treasury Mark-to-Market: Each epoch the Rebase Controller calls DIA's price feeds for USDC, BTC, and tokenised T-Bills; it also requests a virtual price feed for Curve and Balancer LPs. The sum sets the stable-asset numerator in the backing-ratio β.
LP Token Accounting: For volatile-stable pairs (e.g., RZR/USDC Uni-v3 0.05 %), DIA publishes a bound-checked TWAP with an adaptive window: 30 minutes by default, expanding to 2 h if intra-block variance is high. This mitigates the sandwich vector that required custom keepers in Olympus.
RZR Reference Price: A dedicated RZR/USD feed sourced from at least four exchange venues and re-weighted every block with liquidity score sets the reference used by external money markets like Aave forks. Lenders can therefore calculate LTV against a floor that only ratchets upward and a spot oracle.
Why Oracles Matter
Every moving part in a reserve-currency protocol: how many tokens to mint, how high to set collateral ratios, how much a bond should cost depends on unbiased, real-time asset values. An oracle is the bridge between onchain logic and those off-chain truths.
If that bridge is slow, fragile, or manipulable, the protocol can mint unbacked tokens, mis-price bonds, or even hand out free liquidations. A robust oracle mesh is therefore as critical to solvency as the treasury itself.
Interplay with Monetary Policy
A precise oracle feed feeds directly into RZR’s capped-inflation curve: if the BTC sleeve rallies, β rises, and the APR band can climb safely; if a flash crash slices 20 % off volatile holdings, the oracle reports it before the next epoch, β falls, and minting throttles to zero.
Likewise, bond discounts are applied to the DIA's RZR/USD feed, preventing under-priced minting. Because half of every inflow raises the Floor Price directly, an accurate treasury mark-to-market is the only guarantee that each 1% floor tick is fully collateralised.
