Frax is the first fractional 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 US Consumer Price Index). The Frax Finance economy is composed primarily of the two stablecoins, a native AMM (Fraxswap), and a lending facility (Fraxlend).
