Clearstar Boring USDC
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.
You deposit USDC and Clearstar lends it out to borrowers who put up Bitcoin (cbBTC, WBTC) and Ethereum staking tokens (wstETH) as collateral. Borrowers pay interest on the USDC they've drawn; that interest flows to you. The interest rate adjusts based on how much USDC is borrowed relative to how much is available.
Clearstar runs this vault with a narrow focus: nearly all lending (95%) goes against cbBTC, a Bitcoin wrapper, with tiny positions in WBTC and wstETH.
The 3.21% APY comes from borrowing demand against Bitcoin collateral. The vault is fully deployed (0% idle cash), so all deposited USDC is lent out.
The risk is Bitcoin price movement. cbBTC makes up 95% of the book; if Bitcoin falls sharply, those loans move toward the liquidation threshold (86% LLTV). There are no elevated-severity flags, but single-asset concentration is the defining feature.
Good fit for an allocator seeking simple stablecoin yield backed by Bitcoin, if they're comfortable with Bitcoin volatility and a single curator's collateral bet.

The Clearstar Boring USDC vault maximizes USDC yields and allocates exclusively to bluechip and highly liquid assets.
Morpho V2 vault — wraps downstream Morpho markets and V1 vaults via adapters.
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.

March 2023 SVB episode: USDC traded as low as $0.88 before banking exposure was clarified. Mark-to-market loss on 100% of vault TVL (the loan asset is USDC).
V2 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.
Vault 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.
