sGHO

Custom price feed for Aave Savings GHO (sGHO).

Custom price feed for Aave Savings GHO (sGHO). sGHO is an ERC-4626 vault share that accrues value as GHO savings yield accumulates. The price is derived from the vault's current share-to-asset conversion rate multiplied by the Chainlink GHO/USD feed.

Approach

sGHO.convertToAssets(1 sGHO) × GHO/USD (from the NAV's primary feed)

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

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

Price calculation

decimals = sGHO.decimals()                        // vault share decimals
rate     = sGHO.convertToAssets(10^decimals)       // GHO per 1 sGHO (vault decimals)
price    = rate × GHO_USD / 10^decimals

Input	Source	Description
convertToAssets()	IERC4626(sGHO)	GHO backing per 1 sGHO share at the current savings-accrued rate
GHO_USD	NAV base — getPriceDataNoDivergence(GHO) (8 dec)	the NAV's primary GHO/USD price

The ERC-4626 convertToAssets call returns the current exchange rate including all accrued savings yield. The vault decimals are read once at deploy. Result carries the feed's 8 decimals. The GHO/USD term is read from the NAV's primary feed.

Constructor

constructor(
    address sGho_,
    address nav_,
    address baseAsset_
)

Parameter	Description
sGho_	The sGHO 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 (GHO); must equal the vault's asset() — reverts BaseAssetMismatch otherwise

---

Staleness

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