Frax Ether review

Splitting liquidity from yield

Frax separates the position into a liquid token and a yield-bearing one, which concentrates rewards for holders who want them and leaves a clean liquid asset for everyone else. Financially it is elegant; practically it confuses users who expected a single LST that simply accrues, and that confusion is a cost.

Where it lives

The token is deeply integrated in its own ecosystem's pools and much less so elsewhere, so both the yield and the exit route depend on Frax's continued health. Contracts have run since 2022 with published audits and no exploit of the staking contracts on record.

Validators

Run by the protocol and selected partners rather than a permissionless set, which places it with the curated designs rather than with Rocket Pool.

Who it is for

Users already active in the Frax ecosystem who understand the two-token split and want the concentrated yield. Outside that context, a simpler LST with deeper liquidity is the better instrument.

What to watch

Integration and exit liquidity outside its own pools. Both are what would turn the design's elegance into a practical problem if the wider ecosystem contracts.

If you are choosing between this and a plain liquid staking token, the question is whether you will actively use the split. Holders who simply want staked ETH that trades everywhere gain nothing from the extra token and inherit the extra dependency.
