Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

REJECTED. The original thesis correctly identified mutable redemption terms but overstated several incident facts that the available primary record does not prove, including a January 10 effective date, more than $200M of Morpho borrows and losses to unlevered holders from liquidations. Usual announced on January 9, 2025 that the unconditional early 1:1 USD0++ exit would be replaced by a 0.87 USD0 floor plus a 1:1 route requiring USUAL-token contribution. Its January 14 update acknowledged that exit liquidity had been heavily impaired and residual USD0/USD0++ pool liquidity had remained below $20M after sell-offs and withdrawals. The product later became bUSD0 under UIP-12, but the decision variable did not disappear: current governance documentation says the DAO can set the early-exit floor, presently 0.92 USD0, and redemption fees. A locked, governance-administered RWA-backed claim is not equivalent to USD0 at par. Direct USD0, USDC or a separately approved savings token provides a clearer exit. Audits cannot make mutable economic terms immutable.

The research file

Mechanism and lifecycle

USD0 is Usual’s fiat stablecoin claim backed through approved tokenized real-world assets. USD0++ was created by locking USD0 until June 30, 2028 in exchange for USUAL rewards and protocol-yield economics. Early 2025 primary materials described two pre-maturity exits: a floor redemption for less than one USD0, initially 0.87, or a 1:1 early unstake that required contributing a dynamically calculated amount of USUAL. UIP-12 later renamed USD0++ to bUSD0 and introduced rt-bUSD0 as a separate early-exit right token. The current technical documentation still exposes an early redemption function that transfers USUAL. This memo follows that successor instrument because the economic claim and governance-controlled exit surface persist; it does not treat the old ticker as a second allocation.

Governance and control

Usual documentation identifies USUAL and staked USUALx as the principal governance assets and describes proposal, discussion, voting and execution stages. Governable surfaces include token emissions, redemption and unstaking fees, collateral-provider rewards, collateral-provider admission, insurance-fund parameters and the minimum primary-market bUSD0 early-exit value, currently documented as 0.92 USD0. The January 2025 roadmap described a proto-governance model in which contributor proposals would take effect unless vetoed; current documents describe the later transition toward holder governance. The lifecycle is relevant but does not change the holder’s dependency: authorized governance can change the price or cost of an early primary exit, the asset set backing USD0 and treasury support policies.

January 2025 terms event

On January 9, 2025 Usual publicly announced dual primary exits for USD0++: a 0.87 USD0 floor in the application and a forthcoming 1:1 early unstake requiring USUAL burn. It warned highly leveraged USD0++/USDC Morpho users to increase health factor during expected volatility and distinguished hardcoded-price markets scheduled for migration. On January 14, Usual said the 1:1 burn route was live, its USUAL cost would vary with rolling net redemptions and was capped by six months of rewards. The same update stated that residual liquidity in the USD0/USD0++ pool had stayed below $20M after large sell-offs and liquidity withdrawals. These are issuer-authored facts. They support a governance-and-liquidity event, but not every liquidation or loss number circulated in secondary commentary.

Backing, assurance and unresolved record

The terms event was not evidence that USD0 reserve assets had defaulted or that the token contracts were exploited. Usual said USD0++ remained backed by USD0 and continued to describe USD0 as collateralized by approved tokenized Treasury assets. The risk was a mismatch between a locked claim’s economic redemption terms and a market expectation of par liquidity. Smart-contract reviews can assess access control and implementation, but they cannot prevent a permitted governance action from changing a governable floor, fee or collateral policy. Current documentation also shows the product evolved through UIP-6 and UIP-12. A future review must trace every successor contract and proposal rather than infer that the USD0++ terms or ticker remained static after the 2025 event.

Exit, liquidity and alternatives

A holder may sell on a secondary pool, accept the governance-set floor, use the USUAL-funded early redemption route, hold to maturity, or use any successor rt-bUSD0 mechanism whose exact rights are verified. Each path carries a different cost: secondary slippage and depth, a haircut to USD0, exposure to the price and availability of USUAL, or time lock. A token used as collateral can also be liquidated when its market or oracle value falls, but leverage losses belong to the borrower and lending-market design rather than proving loss of reserve backing. Direct USD0 is the closest same-ecosystem alternative because it removes the locked reward layer. USDC supplies a more liquid issuer-controlled dollar alternative; an approved sUSDS position is the relevant savings-token comparison where yield is required. All still need their own issuer and protocol review.

Observable reopening conditions

Reopen for bUSD0 only after a complete executed-rights package identifies the live token, maturity, floor, rt-bUSD0 rights, fee formula, governance delay and every pause or upgrade authority. The minimum primary exit must remain at one USD0 net of all fees for at least twelve consecutive months, or an immutable holder-controlled right must enforce that result without buying or burning another volatile token. Publish daily reserve composition and liabilities, independent attestations, and proposed-size primary and secondary redemption tests through a stressed market. Any future change must have an enforceable notice and holder exit window before it binds existing positions. Without those observations, the rejected allocation and zero sleeve remain the defensible decision.

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.
