Frax Finance is a decentralized lending platform which issues the FRAX stablecoin. Frax Finance algorithmically sustains the value of FRAX through the use of fractional collateral reserves. The collateral used on Frax Finance is split between an accepted collateral (e.g. stablecoins) and Frax Finance’s governance token, FXS. The collateralization ratio for FRAX changes based on its price.
FXS is an ERC-20 token built on the Ethereum network. Its primary uses include governance, minting, staking, and redeeming FRAX, as well as providing liquidity incentives. To participate in Frax Finance governance, FXS can be locked in vote-escrowed FXS (“veFXS”), where voting power increases the longer a token is locked.
