FRAX (Frax Finance) pioneered the fractional stablecoin model and continues to evolve. Now paired with a multi-product DeFi suite (frxETH LSD, sfrxUSD savings stable, Frax Convex). Sophisticated design but circulation smaller than USDC/USDT.
FRAX design evolution
FRAX started as a fractional stablecoin — partially collateralized, partially algorithmic. Over multiple protocol versions, FRAX has moved toward more collateralization. Current design uses over-collateralization + algorithmic components.
Frax multi-product ecosystem
- FRAX — the base stablecoin
- sfrxUSD — yield-bearing FRAX wrapper
- frxETH/sfrxETH — Frax's ETH LSD
- Frax Convex — Curve boost specialization
Verdict
FRAX is a sophisticated multi-product stablecoin suite. Smaller than tier-1 stables but well-designed and continually evolving.
