sUSDS/USD price feed
sUSDS is the savings form of USDS: a dollar that accrues a rate while it sits still. Its letters land one character away from another savings dollar run by an entirely different protocol, which is a hazard for anyone resolving assets by symbol.

Over half the weight sits in the largest pool right now, with the rest divided among smaller venues.
Two savings dollars, one letter apart
Two savings dollars carry names that differ by a single character. They are not related in any way: different issuers, different mechanisms, different sources of yield.
For a person reading carefully the difference is obvious. For a system matching on symbols it is a genuine hazard, since the wrong dollar can be priced against the wrong book without anything looking broken.
This page prices the Sky savings dollar from its own pools. The pair name is the key that keeps that unambiguous.
A dollar that moves for a different reason
A savings token is not pegged to a dollar in the way a plain stablecoin is. It represents a dollar plus whatever has accrued to it, so its value against a dollar drifts upward by design.
Reading it as though it should sit at one dollar produces a permanent apparent deviation. What matters is the rate at which it moves, not the distance from a peg it was never meant to hold.
Who runs on this rate
Treasuries parking idle balances
A savings dollar has to be marked at what it is now, since what it was at deposit stops being accurate immediately.
Systems matching assets by symbol
Two savings dollars a letter apart is the kind of collision that only shows up after it has already gone wrong.
