Staked FRAX (sFRAX) is the savings token of Frax Finance, letting holders of the FRAX stablecoin earn a yield benchmarked loosely to the US policy rate and funded by Frax protocol revenue and treasury assets. It can be redeemed for FRAX at any time with no lock-up. sFRAX scores 50/100 (Tier 4) on the RWTS Trust Score, our lowest stablecoin band, because FRAX's hybrid collateralised-and-algorithmic design and the protocol's reliance on its own revenue carry more structural risk than a fully reserved dollar. The yield is modest and varies with Frax policy.

Staked wrapper around FRAX; FRAX is a hybrid algorithmic/collateralized stablecoin currently ~92%+ collateralized but the algorithmic component remains in the structural design. Closest rubric band for hybrid-mechanism design.
Frax publishes protocol-state dashboard (facts.frax.finance) with full collateralization breakdown; Chainlink price feeds active; on-chain transparency framework.
sFRAX to FRAX is instant via the Frax Savings vault; FRAX to USDC convertible via Curve and other AMMs at par with deep liquidity. Sub-minute end-to-end USDC convertibility.
Multiple smart contract audits (Trail of Bits, Code4rena competitive audits, others); active bug bounty; protocol security operations matured over multiple years.

sFRAX launched September 2023 (~20 months as of May 2026). No material incidents specific to sFRAX. Note: parent FRAX briefly traded slightly below peg during March 2023 USDC depeg event (parent FRAX was 92% USDC-backed at the time; recovered fully when USDC repegged); sFRAX itself launched after this event.
HYBRID_MECHANISMFRAX maintains a hybrid algorithmic/collateralized design. Algorithmic component is small (~8%) but structurally present. Yield rate (Frax Savings Rate) is highly variable based on AMO performance; data.ts notes recent rate at 1.25% vs historical 5-10%.
PARENT_FRAX_HISTORICAL_DEPEG_USDC_2023Parent FRAX briefly traded below peg during March 2023 USDC depeg (FRAX was ~92% USDC-collateralised). Full recovery within hours when USDC repegged. sFRAX launched September 2023 after this event.
Caveats document operational realities that don't change the dimensional score but shape practical use.
Beyond sFRAX's own score, two structural questions matter: what is it built on, and what has broken before in this part of the market. A high score in isolation can still carry hidden, shared exposure.
What this and similar assets are built on, and where contagion could spread.
The depegs, defaults, and exploits that inform the Track Record dimension.
Liquidity read: TVL of $65.28M indicates developing on-chain liquidity. Lock-up: None.
