What is Frax Finance?

Frax Finance stands out in the decentralized finance sector by issuing three distinct stablecoins: FRAX, which is pegged to the US dollar; FPI, linked to a basket of consumer goods for a novel unit of account; and frxETH, tied to Ethereum for smart contract integration. These stablecoins aim to offer stability and diversity in financial transactions, responding to the need for reliable digital assets in a fluctuating cryptocurrency environment.

The ecosystem is reinforced by subprotocols that extend its functionality: Fraxlend facilitates lending and borrowing within the Frax ecosystem; Fraxswap, an Automated Market Maker, ensures liquidity and enables efficient trading; and Fraxferry allows for the movement of tokens across blockchains, broadening the protocol's usability and access.

FRAX v3 represents the protocol's evolution towards full collateralization and a steadfast USD peg, employing smart contracts and governance for a robust and secure stablecoin offering. This iteration underscores Frax Finance's commitment to providing a secure, versatile financial infrastructure that addresses the inherent challenges of the cryptocurrency market.

How Does Frax Finance Work?

Frax Finance stabilizes its FRAX stablecoin using a hybrid model that mixes collateral assets with algorithmic techniques. This system dynamically adjusts the collateralization ratio based on market conditions to ensure FRAX's value remains pegged to the US dollar. The protocol incorporates specialized subprotocols:

  • Fraxlend: A lending platform for creating and managing loans within the Frax ecosystem.
  • Fraxswap: An Automated Market Maker (AMM) that enhances liquidity and supports trading activities.
  • Fraxferry: Facilitates the transfer of Frax tokens across different blockchain networks, promoting wider usability and interoperability.

Governance by FRAX stakeholders guides protocol adjustments and strategic decisions, ensuring the system remains responsive to the evolving financial landscape. This structure allows Frax to maintain stability and scalability, serving as a cornerstone for decentralized finance by balancing traditional financial mechanisms with innovative DeFi solutions.

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.
