Vault Street primeUSD

Vault Street primeUSD is a permissioned Ethereum carry vault. Valiant allocates USDC into tokenized Treasury and investment-grade credit funds, pledges those positions in DeFi lending markets and reinvests borrowings toward an indicative 8x leverage target. The protocol API read on 2026-08-15 reported about $6.36M, but size does not decide: recursive collateral and debt amplify fund, rate, liquidation, NAV and unwind risk. The shared v1 leveraged-looping dossier controls.

Review triggers: events that reopen the verdict
• Ships an economically separate product whose return does not depend on pledged collateral, borrowing and reinvestment
• The unleveraged product publishes controlling eligibility and redemption terms, independently reconciled NAV and custody, complete authorities and a proposed-size stressed exit against named Treasury and credit alternatives

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

The research file

Applicability to the surveyed record

Vault Street documents primeUSD as a permissioned Ethereum vault token for a leveraged carry strategy: KYB-approved users deposit USDC, the company allocates into tokenized Treasury and investment-grade credit funds, pledges those positions in DeFi lending markets, and reinvests borrowings. This establishes the surveyed RWA allocator and its receipt-token mechanism without converting the class application into an individual approval review.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-15 classified Vault Street primeUSD as RWA, reported only Ethereum, and showed approximately $6.36M TVL. That figure describes reported accounting scale, not quality or executable capacity. The current vault schedule identifies the same Ethereum token and an indicative 8x leverage target; the recursive debt structure, not venue size, determines this class application.

Control, liquidation, NAV and exit applicability

Valiant Digital Assets retains discretion over fund providers, lending integrations, collateral mix and leverage. Borrowed assets are reinvested, so adverse fund pricing, borrowing-rate changes, collateral haircuts or liquidation thresholds can force deleveraging and transmit loss through the reported NAV. Deposits, transfers and redemptions are allowlist-gated; standard redemption targets five business days, can extend to twenty in stress, and express next-day processing is non-binding and limited by available liquidity and a 10%-of-NAV aggregate cap. Exit therefore requires company execution, fund-wrapper liquidity and a lending-market unwind.

Why the class rule decides

The shared v1 leveraged-looping dossier controls because primeUSD recursively uses pledged yield assets and reinvested debt to amplify carry toward an indicative 8x target. That payoff is out of scope regardless of scale or disclosure quality. Reopen only for an economically separate unleveraged product; then review legal recourse and eligibility, issuer and contract control, NAV, underlying funds and custody, audits and incidents, allowlisted redemption performance, proposed-size stressed exit and named unleveraged Treasury and credit alternatives.

Class rule

The leveraged looping class is outside the approved structures, so every protocol in it is not approved until the rule changes. The rule is about the structure, not an adverse finding about this protocol, and it is not a client instruction. The events that would reopen it are listed with the memo.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
