SUSDAI/USD price feed
The pools behind sUSDai are built like reservoirs: vault-style venues that hold far more capital than they keep standing near the current price. Deep reservoirs, narrow taps; the level on this page forms at the taps.

Book composition · auto-observed
This book is shared across chains at the moment, with one pool holding the largest single slice.
Deep reservoirs, narrow taps
The gap is the first thing to understand about this book. Vault-style venues spread their liquidity across wide price ranges, so a pool can hold tens of millions of dollars while keeping a comparatively thin band near the current price. Both figures are true; they answer different questions.
Total value answers how much capital lives with the token. Depth within one percent answers what a trade can move through right now without shifting the level. On most books the two rhyme; on vault-shaped books like this one they can diverge sharply, which makes quoting either number alone misleading.
The feed therefore publishes both, per venue, per side, per block. Readers who mark size against this token can pick the figure that matches their question, with the block attached.
New collateral, new chain
sUSDai is the staked, yield-accruing form of USDai, a synthetic dollar collateralized by loans against AI computing hardware. That is a new kind of backing for this catalog, stated here as a design fact rather than a verdict either way.
The geography is young too: this token built one of the first real markets this catalog observed on Plasma, a chain that joined the observed set recently, alongside footing on more established rails. New collateral on new rails; the measurement style stays the old one.
Whatever dollar legs the book carries clear through their own markets before this level forms. The underlying USDai reports a net asset value of its own; the wrapper's climbing level is the market's running answer to what that stake is worth.

Treasuries screening frontier collateral
A dollar backed by hardware loans is a new category; a block-pinned market level is how a desk evaluates it without taking anyone's brochure.
Risk desks comparing TVL to depth
This book is a textbook case of reservoir versus tap; the per-venue figures make the distinction usable.
Desks routing on Plasma
This token was early to build a market on Plasma; anyone moving dollars on young rails gets the same measured reference there as anywhere else.
