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

Aegis issues YUSD and pays holders from funding-rate arbitrage: delta-neutral positions across spot and perpetual markets, with funding fees disbursed three times daily. TVL was $35.9M at the 2026-08-14 survey, below the $100M materiality line, and size alone rejects it: one practice advising 100 households moves $1M to $8M into a venue on the same research, and at this size that book becomes the exit crush, whatever the protocol’s quality. Above the line it would be reviewed as a basis-trade dollar, the structure whose yield inverts when funding turns negative.

The research file

Mechanism applicability

Aegis describes YUSD as a synthetic dollar whose reserves pair Bitcoin spot held through institutional custody and off-exchange settlement with matched short BTC perpetual positions; staking YUSD produces sYUSD and distributes strategy yield. That establishes a basis-trade stablecoin with custody, exchange, hedge and reserve-management dependencies. It does not validate reserve segregation, hedge completeness, counterparty exposure or the advertised peg.

Current observation and scope

The DefiLlama protocol API read on 2026-08-15 showed about $35.8M of tracked Aegis YUSD TVL across Ethereum and BSC, below the shared v1 dossier’s $100M line. The official site and application remained available and described current YUSD minting and staking. Hedge distribution, custody agreements, reserve liabilities, governance, audits, incidents and realized funding performance remain deferred rather than inferred from the product description.

Exit applicability

Aegis advertises minting and liquid access through its application, but an economic exit ultimately depends on YUSD market liquidity and on the system settling or transferring its custody and derivatives exposures. At roughly $35.8M of aggregate TVL, a practice-sized allocation could be material to available redemption or secondary liquidity. The class decision therefore rests on observable capacity, not a claim that the hedge or peg has already failed.

Why the class rule decides

The shared v1 below-materiality dossier controls this application. Reopen only after reproducible surveys show at least $100M of protocol TVL continuously for 30 days and the reserve and hedge system remains observable. Then verify reserve assets and liabilities, custody segregation, exchange and settlement counterparties, hedge matching, governance and upgrade control, audits and incidents, fees, peg behavior, and stressed redemption liquidity. Passing the threshold would begin review, not confer approval.

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.
