Asymmetry USDaf

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 size floor. Its direct redemption returns a changing collateral mix rather than a chosen cash asset, and collateral, oracle and market-liquidity dependencies remain relevant, but size decides here. One practice’s $1M to $8M same-research book would exceed the venue, so the file remains rejected because it is too small, not because of an individual finding about protocol quality. We do not open that individual review until it clears the size floor.

Review triggers: events that reopen the verdict
• TVL sustained above the retired TVL threshold for 30 days

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 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 change the decision that it is below the size floor or open an individual review.

Control and dependency applicability

The core deployment is documented as immutable, permissionless and non-upgradeable, which reduces administrative upgrade risk. It does not remove reliance 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 changing 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 exit facts would matter in an individual review, but the measured $424,000 venue is already too small for advised-client sizing, so we do not open that review.

Why the dossier still applies

DefiLlama measured approximately $424,000 on Ethereum on 2026-08-16. That is 0.42% of the size floor, so the shared below-materiality dossier decides regardless of the immutable design. Do not open the individual review until TVL remains above the size floor for 30 days. Then review collateral concentration, oracle resilience, liquidation capacity and executable USDaf exit depth.

Research status

This is a capacity-unproven record for Asymmetry USDaf, not a quality rejection or approval. Reported TVL says how big the venue is, not what the client owns, who can change the rules, or how a position exits at a proposed size. The individual review opens when the protocol clears the size floor.

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.
