What is Frax Finance

Frax is an innovative DeFi protocol that issues and supports three stablecoins: FRAX, pegged to the USD; Frax Price Index (FPI), tethered to a basket of consumer goods; and FraxEther (frxETH), anchored to ETH. The protocol utilizes three interconnected subprotocols: Fraxswap for collateral rebalancing and liquidity deployment, Fraxlend for loan origination and collateral asset onboarding, and Fraxferry for token transfers across multiple blockchains. The protocol is governed through the native token Frax Share (FXS) and FPIS tokens, which manage the Frax ecosystem and FPI, respectively.

An essential feature of Frax Finance is the Algorithmic Market Operations Controller (AMO), a system of autonomous central banking legos enabling open market operations without affecting the FRAX peg. Paired with the fractional-algorithmic stability mechanism, the AMO maintains a balance between supply and demand for FRAX, ensuring a tight price peg and promoting a robust and efficient platform for decentralized finance transactions.

What is FRAX?

FRAX is a stablecoin launched by Frax Finance, a decentralized finance protocol. Pegged to the United States dollar (USD), FRAX is designed to maintain a 1:1 value ratio, aiming for $1 FRAX per $1 USD.

The protocol employs a combination of on-chain assets and algorithmic mechanisms to ensure this peg. Should FRAX's price deviate from $1, the system adjusts by manipulating the collateral ratio, working to bring the value back to parity. As such, FRAX offers the benefits of cryptocurrencies, like decentralization and transparency, while mitigating high price volatility making it a safe stablecoin to earn yields in DeFi.

What is frxETH?

In the Frax Finance ecosystem, Ethereum (ETH) exists as liquid staking derivative under the names frxETH and sfrxETH. frxETH, a stablecoin, is designed to mirror the value of ETH on a 1:1 basis, maintained within a target range of 0.9900 to 1.01 ETH per 1 frxETH. It's minted in equal amounts whenever ETH is contributed to the system.

Meanwhile, sfrxETH is a yield-earning variant of frxETH. Users can convert their frxETH into sfrxETH to gain staking rewards. As these rewards are accrued, additional frxETH is minted and added to a vault. Hence, sfrxETH holders own a share of an ever-growing frxETH pool, mirroring systems like Aave's aUSDC or Compound's cUSDC.


What can I do with frxETH and FRAX?

frxETH and FRAX, tokens from the Frax Finance ecosystem, have important roles in decentralized finance (DeFi). On platforms like Convex Finance and Curve Finance, you can deposit these tokens as collateral to earn yield. 

You can also provide liquidity with these stablecoins in various pools, earning transaction fees in return. Additionally, staking and yield farming opportunities exist, letting you lock tokens for rewards. These tokens thus offer a mix of stability and income-generation within DeFi.

What is Frax Shares (FXS)?

Frax Shares (FXS) is the governing and utility token of Frax Finance, a cornerstone of the ecosystem. It allows holders to vote on key parameters and its supply is deflationary with growing FRAX demand. FXS can be locked into veFXS, unlocking additional privileges. With a market capitalization of $500 million, FXS stands within the top 100 crypto assets globally.
