Frax (FRAX) is a stablecoin with a fractional-algorithmic stability mechanism. The open-source Frax protocol offers scalability, decentralization, and on-chain transactions. It addresses issues in existing stablecoin protocols by combining collateralization and algorithmic design. Frax stablecoin (FRAX) is the liquidity pool token, redeemable for traditional currency, while Frax Shares (FXS) serves as the governance token. The protocol accepts various collateral types and promotes stability. Sam Kazemian, with support from Stephen Moore, founded Frax in 2019.
