Plain-English summary of this vault — what it does, who runs it, where the yield comes from, and what could break it. Generated from the same deterministic inputs shown elsewhere on this page; the numbers are the source, this is just the explanation.
What this vault does
Depositors put in USDT and earn 2.19% APY as SparkDAO lends it out fully deployed across four blue-chip collateral types—Bitcoin (WBTC and cbBTC), Ethereum staking tokens (wstETH), and a USD stablecoin (sUSDS). Borrowers post these assets as collateral, and the rate is set by supply and demand on Morpho Blue's matching engine; no idle cash buffer exists.
Who runs it
SparkDAO runs this vault with a focused, collateral-conservative approach: 100% of the USDT is lent against highly liquid, major assets across a balanced four-way split.
Where the yield comes from
The 2.19% APY comes entirely from borrowing demand against WBTC, wstETH, sUSDS, and cbBTC collateral, with all deposited USDT deployed (0% idle). No incentive programs are listed.
What could break it
The main risks are price moves in the four collateral types, especially given tight liquidation thresholds (LLTV 86–97%); if Bitcoin or Ethereum price falls sharply, collateral may approach liquidation levels. sUSDS carries depeg risk, though the depeg signal currently shows "healthy" status.
Who this is for
Good fit for conservative allocators seeking simple, fully deployed USDT yield backed by blue-chip collateral if comfortable with liquidation-driven volatility in Bitcoin and Ethereum prices.
USDT is trading within normal range. Both market spot and Chainlink agree this vault's loan asset is on peg — no peg risk affecting NAV right now.

Warning floorfloor
Hard min from Morpho's own flags on the vault or its active markets.
Structuralweight 28%
Share-weighted collateral quality + LLTV buffer adequacy. Correlation-aware.
Liquidationweight 20%
Headroom (1 − LLTV) measured in σ-units of 30d realized vol, amplified by utilization.
Yield anomalyweight 20%
Peer-cohort z-score plus absolute-yield band. Excess yield is risk you may not yet model.
Concentrationweight 12%
Market HHI + asset-class HHI + curator's universe TVL share.
Liquidityweight 10%
Util curve position, share locked above 95%, idle buffer.
Maturityweight 10%
Vintage + TVL-time integral. V2 vaults carry an opacity surcharge.
Depeg floorfloor
Hard min from active depeg signal on the loan asset.
Composite = max(Σ weighted + floors). Warning and depeg floors are hard minimums; the weighted sum of the structural factors is the base. A floor highlighted in amber means it is what determines the final score — the protocol or peg signals are louder than our structural model.

What this vault actually does
Spark blue-chip USDT vault. Lending against the lowest risk crypto and real-world assets. Curated by Spark which allocates billions in assets across all of DeFi. See data.spark.fi for more details.
Where the yield comes from
Morpho V2 vault — wraps downstream Morpho markets and V1 vaults via adapters.
Why they may not
Some V2 adapters point at Morpho Blue markets directly; their underlying market detail isn't resolvable in the universe-level fetch, so this vault carries a V2 opacity surcharge in the risk model.
Hidden exposure map
What this vault is actually exposed to — including dependencies that are not visible from the strategy name.

StablecoinLoan asset supplied by the vault.
Reading this map. Direct exposures are the assets the vault holds or lends against. Indirect dependencies (Tab 3) include the protocols that mint those assets, the oracles pricing them, and the bridges that move them. An incident at any indirect dependency can damage the vault even when the direct collateral looks healthy.

V2 adapter routing failure
rare
computedV2 vaults route through adapters into downstream venues. A misbehaving adapter (paused, drained, or pointing at a compromised target) can lock or mismark a portion of the vault until governance acts.

$50M same-day redemption
possible
computedVault has $0M idle buffer (100% of $0M TVL). $50M of the $50M request queues; the redeemer takes a ~0.50% forced-exit discount weighted across collateral mix plus 0-day TVM cost. $50M of the request exceeds the vault's $0M TVL and cannot be redeemed at all.
