stUSDT
Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.
stUSDT 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 it sits below our $100M materiality line. Rejected on size: an advisory book moved into a venue this size on the same research becomes the exit crush, whatever the product’s quality. A reopened memo would need to verify what the token actually holds and who custodies it, and would also need Tron 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.
- Publishes independently audited holdings, legal claim and seniority, custodian reconciliation, concentration and loss history, and stressed redemption outcomes on an approved chain
The research file
Mechanism
Users stake supported stablecoins and receive rebasing stUSDT; an RWA arranger allocates the backing into off-chain assets and a performance oracle reports returns used for rebase accounting. The token is an on-chain receipt for an off-chain investment program, not direct title to disclosed Treasury securities.
Control and operating evidence
The white paper assigns asset selection and management to the RWA arranger, custody to an external custodian and reporting to a performance oracle. Public material does not provide position-level obligors, legal seniority, independently reconciled custody or a complete realized loss history. Tron settlement is an additional rejected-chain dependency.
Exit consequences
Redemption depends on protocol liquidity and liquidation or maturity of underlying RWAs rather than autonomous on-chain collateral seizure. Oracle delay can separate the displayed balance from realizable proceeds, and a run can force gates or delayed settlement. Secondary sale realizes any discount to USDT.
Why the class rule decides
The holder lends through an opaque off-chain allocation and depends on centralized arranger, custodian and oracle performance. That matches the off-chain-credit class more directly than today’s $62.8M size. Review requires audited holdings, legal claims, custody reconciliation, concentration, losses and stressed redemptions, plus an approved settlement chain.
Sources
The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls
The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
| Chain | Verdict | Grade | Control constraint |
|---|---|---|---|
| Tron | Rejected | freezable | governance has been bypassed at nine-figure scale without a vote; treat it as centrally directed. |
| Ethereum | Approved | sovereign | No sequencer, no upgrade key, no operator who can be compelled — rule changes require social consensus. |
