About Frax Finance

Frax is the first and only stablecoin with parts of its supply backed by collateral and parts of the supply algorithmic. The stablecoin (FRAX) is named after the “fractional-algorithmic” stability mechanism. The ratio of collateralized and algorithmic depends on the market’s pricing of the FRAX stablecoin. If FRAX is trading at above $1, the protocol decreases the collateral ratio. If FRAX is trading at under $1, the protocol increases the collateral ratio.

FRAX : is the stablecoin targeting a tight band around $1/coin.
Frax Shares (FXS) : is the governance token which accrues fees, seigniorage revenue, and excess collateral value.
