Book composition · auto-observed
The book rests on a single active pool at present; there is nothing to weight it against.
The exit price stakers actually pay
A staking protocol can tell you what one stSUI should be worth in SUI. The pool market tells you what it is worth right now, to someone who wants out before the unbonding queue clears.
The gap between those two numbers is real information. A discount means immediate liquidity costs something; a premium means demand for the yielding form is outrunning fresh deposits.
ML Data reads stSUI at its traded rate instead of the protocol's stated conversion, so the premium or discount shows up in the series rather than being defined away.
Who runs on this rate
Risk desks
Collateral marked at a stated conversion hides exactly the stress a risk model exists to catch. The traded rate keeps the mark honest.
Protocols accepting stSUI
Lending markets listing a staked asset need its market level, since liquidations happen at pool prices, not at theoretical ones.
