stUSDT

stUSDT does not meet our size floor. It is a real-world-asset product on Tron and Ethereum: holders deposit stablecoins and receive a token said to earn yield from tokenized off-chain assets. At $62M TVL at the 2026-08-14 survey, an advisory book moved into a venue this size on the same research could overwhelm its exits, whatever the product’s quality. We do not open an individual review until it clears the size floor. A reopened memo would need to verify what the token actually holds and who keeps the assets. Tron would also need to pass chain-level vetting, which it has not. The more accurate basis is off-chain credit: the published design relies on an RWA arranger, custodian and performance oracle rather than assets a holder can inspect or liquidate on-chain.

Review triggers: events that reopen the verdict
• Publishes independently audited holdings, legal claim and seniority, custodian reconciliation, concentration and loss history, and stressed redemption outcomes on an approved chain

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

Mechanism

Users stake supported stablecoins and receive rebasing stUSDT. An RWA arranger puts the backing into off-chain assets, and a performance oracle reports the returns used for rebase accounting. The token is an on-chain receipt for an off-chain investment program. It does not give direct title to disclosed Treasury securities.

Control and operating evidence

The white paper gives asset selection and management to the RWA arranger, custody to an outside custodian and reporting to a performance oracle. Public material does not show position-level obligors, legal seniority, custody records checked by an independent party or a complete history of realized losses. The product also depends on settlement through Tron, a rejected chain.

Exit consequences

Redemption depends on protocol liquidity and the liquidation or maturity of the underlying RWAs, not the automatic seizure of on-chain collateral. An oracle delay can separate the displayed balance from the proceeds a holder can realize. A run can force gates or delayed settlement. A secondary sale locks in any discount to USDT.

Why the class rule decides

The holder lends through an opaque off-chain allocation and depends on a central arranger, custodian and oracle. That fits the off-chain-credit class more directly than today’s $62.8M size. A review requires audited holdings, legal claims, custody records checked against the assets, concentration, losses and stressed redemptions. It also requires an approved settlement chain.

Class rule

The off chain credit 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.

Sources

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

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.
