sUSDai: redemption value, spread and APY
sUSDai is the staked, yield-bearing form of USDai from USD.AI (Permian Labs). ArbScreener compares what sUSDai costs on a DEX with the USDai it redeems for on-chain, and shows the gap as a spread and an APY — priced in USDai, not USD.

How ArbScreener prices sUSDai
sUSDai is an ERC-7540 asynchronous-redeem vault. Its value comes from redemptionSharePrice(), the conservative price the USD.AI app uses, not convertToAssets, which overstates it. Unstaking requests are processed in batched windows; the next window is read live from the contract.
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 USDai, never USD.
