RWIV

Custom price feed for the Nexus Mutual Real-World Investments Vault (RWIV).

Custom price feed for the Nexus Mutual Real-World Investments Vault (RWIV). RWIV is an ERC-4626 vault share backed by USDC. The price is derived from the vault's current share-to-asset conversion rate multiplied by the USDC/USD price read from the NAV's own primary feed.

Source: RWIV_CustomPriceFeed.sol

The USDC/USD term is sourced from the NAV's own selector — see Base/USD from the NAV's own selector.

Approach

RWIV.convertToAssets(1 RWIV) × USDC/USD (from the NAV's primary feed via getPriceDataNoDivergence(USDC))

RWIV price feed — how its oracle inputs compose into a USD price, with the staleness gate.

Price calculation

decimals = RWIV.decimals()                        // vault share decimals
rate     = RWIV.convertToAssets(10^decimals)       // USDC per 1 RWIV (vault decimals)
price    = rate × USDC_USD / 10^decimals

Input	Source	Description
convertToAssets()	IERC4626(RWIV)	USDC backing per 1 RWIV share at the current vault rate
USDC_USD	NAV base — getPriceDataNoDivergence(USDC) (8 dec)	the NAV's primary USDC/USD price

The ERC-4626 convertToAssets call returns the current exchange rate. The vault decimals are read once at deploy. Result carries the feed's 8 decimals. The USDC/USD base term is read from the NAV's primary feed rather than a hardcoded oracle.

Constructor

constructor(
    address rwiv_,
    address nav_,
    address baseAsset_
)

Parameter	Description
rwiv_	The RWIV vault address (also used to read vault decimals)
nav_	NAVCalculator (proxy) — supplies the base stablecoin's USD price via getPriceDataNoDivergence
baseAsset_	The registered base stablecoin whose USD price is read (USDC); must equal the vault's asset() — reverts BaseAssetMismatch otherwise

---

Staleness

The price is stale if the base USD price is ≤ 0, or if the NAV reports the base asset (USDC) stale — all its feeds stale. The base leg's updatedAt comes from the NAV's selected USDC feed. The convertToAssets rate has no heartbeat — it is a live view on the ERC-4626 vault.
