The memo
REJECTED FOR BOTH SYMBOLS, though the two do not fail for the same reason and one is more reopenable than the other. The prior thesis was factually wrong: current Frax materials do not identify Maple, Ondo or Mountain as frxUSD reserves. Frax says the present backing consists of BlackRock BUIDL and Superstate USTB, while its documentation permits a wider set of cash-equivalent custodian assets and delegates reserve composition to Frax Inc. The more important error was treating frxUSD and sfrxUSD as one risk. frxUSD is a fully collateralized stablecoin redeemable against available enshrined-custodian assets. sfrxUSD is a managed yield vault whose Benchmark Yield Strategy may rotate all staked frxUSD among Ethena carry trades, DeFi AMOs and Treasury/IORB strategies. That is not Treasury exposure and can import venues this registry rejects — sfrxUSD is rejected on that design fact and stays rejected absent a hard mandate exclusion of those venues, a standing condition rather than a temporary evidence gap. frxUSD is different: Frax publishes the permitted designs and current headline backing, but this review could not reproduce a dated, line-by-line reserve report with custodian values and encumbrances — no single Frax-published document gives that, and a Chaos Labs review confirms directly that "no comprehensive unified attestation covering all frxUSD reserves" exists. This registry has no per-symbol verdict field, so a single entry covering both symbols cannot record "reject sfrxUSD, hold frxUSD to a materially higher bar than most tokenized-RWA approvals get" without either overstating frxUSD or understating sfrxUSD; a `project` id split was considered and rejected because `project` is the exact join key against the live DefiLlama feed; a fabricated `frax-frxusd` slug would silently never match live pool data. Rejecting the whole entry is therefore the honest position: unproven is not approved. frxUSD alone has a real path back once the schema supports a per-symbol verdict, or once a reproducible reserve report exists and is checked against a standalone entry built for it.
What would reopen the file
- Any reserve asset outside cash, insured deposits, short government securities, or approved tokenized Treasury funds
- Reserve composition or sfrxUSD allocation not reproducible from dated public reporting
- frxUSD backing below 100% or a custodian redemption failure
- Any sfrxUSD allocation to an unapproved carry, lending, liquidity or private-credit strategy
- Proposed-size frxUSD or sfrxUSD exit exceeding the written cost or timing limit
