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.

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.

Is sFRAX safe?
sFRAX (Staked FRAX) scores 50/100 on the independent RWTS Trust Score, which places it in Synthetic & Structured (Tier 4). Tier 4 is the highest-risk tier: synthetic or structured backing where the yield comes with genuine structural risk, not a hard claim. Backing: FRAX (hybrid algorithmic + collateralized). It is independently audited. The score reflects backing, verification, redeemability, audit, regulatory standing, and track record, not headline yield. We rate. You decide.
