fxSAVE: redemption value, spread and APY
fxSAVE is the savings vault of the f(x) Protocol (AladdinDAO), holding fxBASE (fxUSD Save). ArbScreener compares what fxSAVE costs on a DEX with the fxUSD it redeems for on-chain, and shows the gap as a spread and an APY — priced in fxUSD, not USD.

How ArbScreener prices fxSAVE
fxSAVE is an ERC-4626 vault whose asset is fxBASE (fxUSD Save), not a $1 token. The vault's convertToAssets amount is converted with fxBASE's net asset value, and the result is treated as dollars.
The redemption spread is what redeeming returns minus what buying costs on a DEX, as a fraction of the cost, at a standard quote size and net of the protocol's fee. The APY annualizes that spread over the redeem wait (counted as at least one day), so a discount that takes weeks to collect ranks below the same discount collected today. Everything is in fxUSD, never USD.
