Clearstar USDC Reactor
- Unrecognized Collateral AssetYELLOWsYUSD / vbUSDC
Morpho has flagged the sYUSD / vbUSDC market: unrecognized_collateral_asset.
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.
Depositors put in vbUSDC (a Katana-wrapped stablecoin) and the vault lends it out on Morpho Blue against borrowers who post yvAUSD as collateral. The vault earns interest paid by those borrowers plus a small boost from Morpho incentive programs; the interest rate is set by supply and demand between lenders and borrowers on each market.
Clearstar runs the vault and currently deploys 100% of capital into a single yvAUSD market at high utilization (86%), with no cash buffer.
The 4.63% APY comes from 3.94% in borrowing demand against yvAUSD collateral and 0.69% from Morpho protocol incentives on that market.
The vault has zero diversification—all capital is lent against one collateral type (yvAUSD). yvAUSD itself carries unrecognized collateral status according to Morpho's official warnings (yellow flag), and the 86% loan-to-liquidation-value ratio leaves limited margin if that collateral loses value. No idle cash means any redemption pressure would force asset sales or delays.
Avoid unless you have high conviction on yvAUSD's stability and can tolerate single-asset concentration and Morpho's unrecognized-collateral warning.

The Clearstar vbUSDC Reactor vault maximizes vbUSDC yields while fostering the growth of high-quality collateral assets. By combining strategic asset selection with intelligent routing across efficient lending markets it creates a flywheel of liquidity and sustainability.

The honest version. Every structural failure mode this vault is exposed to, ranked by severity. If you want to know whether to invest, start here.
A market (sYUSD / vbUSDC) is reporting supply APY at or above 50% — peak 1434% on sYUSD / vbUSDC. This is almost always a degenerate IRM state (100% utilization, dust-sized supply, or a stale post-liquidation snapshot) rather than real lending demand. The vault's headline APY is being averaged up by these positions; treat it as transient. 0.0% of TVL sits in the affected market.
Cap-weighted utilization is 85.7%, leaving little idle buffer. Large same-day redemptions may queue behind active loan repayments.
What this vault is actually exposed to — including dependencies that are not visible from the strategy name.
Every market the vault has supplied into, with current LTV, LLTV, oracle, and IRM. Idle balances are listed explicitly.
Modeled NAV impact under historical and hypothetical tail events. Each impact = − (shock magnitude) × (vault exposure) × (pass-through). Hover the calculator icon for the per-scenario formula.
Tail-case: a vulnerability surfaces in Morpho Blue that affects the vault's largest single market (100% of TVL). Modeled at 50% loss on that exposure; full vault is not assumed at risk since markets are isolated.
Curator routes into a market that develops bad debt or an oracle break. Worst single position is 99.9% of TVL; top-3 concentration is 100%. Modeled at 50% bad-debt recovery on the worst position.
100% of TVL is in markets running >85% utilization. Redemption requests on that slice queue until borrowers repay; remaining LPs absorb a small forced-exit discount.
Vault has $0M idle buffer (14% of $0M TVL). $50M of the $50M request queues; the redeemer takes a ~0.50% forced-exit discount weighted across collateral mix plus 12-day TVM cost. $50M of the request exceeds the vault's $0M TVL and cannot be redeemed at all.
48h sequencer halt on Katana. Collateral drifts while liquidations are frozen; the LLTV buffer absorbs liquidation-clearable moves, the excess accrues as bad debt. Plus a small forced-exit discount on the 100% of TVL sitting in markets above 85% utilization. Total -0.50% NAV loss.
