Staked Frax Ether (sfrxETH) is the yield-bearing liquid staking token of Frax Finance, representing ETH staked through Frax's validators with rewards compounding into the token's value. It concentrates the staking yield into a single accumulating token while frxETH handles the liquid, non-yield leg. sfrxETH scores 61/100 (Tier 3) on the RWTS Trust Score: a functioning two-token staking design with reasonable liquidity, set against smart-contract risk, a smaller validator footprint than Lido or Rocket Pool, and dependence on Frax's broader protocol health. The yield tracks Ethereum staking rewards.

Caveats document operational realities that don't change the dimensional score but shape practical use.
Beyond sfrxETH'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 $97.75M indicates developing on-chain liquidity. Lock-up: None (liquid).
