Asymmetry USDaf
Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.
USDaf is an overcollateralized Liquity V2 stablecoin on Ethereum, borrowed against BTC and yield-bearing stablecoins through immutable contracts. The 2026-08-16 survey measured about $424,000, less than one percent of the $100M materiality floor. Its direct redemption returns a dynamic collateral mix rather than a chosen cash asset, and collateral, oracle and market-liquidity dependencies remain relevant, but size is dispositive here. One practice’s $1M to $8M same-research book would exceed the venue, so the file remains rejected on materiality rather than presented as an individual protocol-quality finding.

The research file
Mechanism applicability
Asymmetry identifies USDaf as a Liquity V2 deployment. Borrowers open overcollateralized positions against BTC and yield-bearing stablecoins, choose an interest rate and remain subject to collateral-specific loan-to-value limits and liquidation. Stability Pools absorb liquidated debt and collateral before just-in-time liquidation or redistribution. Those facts establish a CDP stablecoin; they do not alter the below-materiality decision.
Control and dependency applicability
The core deployment is documented as immutable, permissionless and non-upgradeable, which narrows administrative upgrade risk. It does not remove dependency on each accepted collateral, its oracle and secondary-market liquidity. Asymmetry’s risk disclosure says a sudden collateral collapse can defeat orderly liquidation and that withdrawal can be restricted while a loan is unsafe.
Exit applicability
A USDaf holder can redeem at face value less a fee, but receives a dynamic mix drawn from the system’s collateral rather than selecting one asset. A borrower must repay debt and restore a safe position before withdrawing collateral. These are decision-grade exit facts, but the measured $424,000 venue is already too small for advised-client sizing.
Why the dossier still applies
DefiLlama measured approximately $424,000 on Ethereum on 2026-08-16. That is 0.42% of the $100M floor, so the shared below-materiality dossier remains fundamental regardless of the immutable design. Reopen only after TVL remains above $100M for 30 days; then review collateral concentration, oracle resilience, liquidation capacity and executable USDaf exit depth.
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.
