• Frax (FRAX) is a fractional algorithmic stablecoin partially backed by collateral and partially stabilized algorithmically. The ratio of collateralization and algorithmic depends on the market price of the FRAX stablecoin. If FRAX is trading at above $1, the protocol decreases the collateralization ratio. If FRAX is trading at under $1, the protocol increases the collateralization ratio.

  • Frax Share (FXS) is the non-stable, ERC-20 governance token of FRAX with the following use cases:

    • Governance: Grants holders governance rights to add/adjust collateral pools, set minting/redemption fees, and to change the refresh rate of the collateralization ratio.

    • Staking: Stake in various pools to earn interest with preferred APY.

    • Minting & Redeeming: FXS will be burned when minting FRAX and minted when redeeming FRAX.

    • Rewards: FXS rewards will be claimable for users who deposit Uniswap LP tokens to incentivized pairs.

  • At genesis, FRAX is 100% collateralized, meaning that minting FRAX only requires placing collateral into the minting contract. During the fractional phase, minting FRAX requires placing the appropriate ratio of collateralization and burning the ratio of FXS.

  • As of February 18th 2021, the total supply of FXS is 100,000,000 and the current circulating supply is ~5.34%.
