Frax is a fractional-algorithmic stablecoin protocol. Frax is open-source, permissionless, and entirely on-chain – currently implemented on Ethereum and 12 other chains. The end goal of the Frax protocol is to provide a highly scalable, decentralized, algorithmic money in place of fixed-supply digital assets like BTC. The Frax ecosystem has 2 stablecoins: FRAX (pegged to the US dollar) & FPI (pegged to the Consumer Price Index).
