Summary of Frax Ether
- Frax Ether is a liquid ETH staking derivative designed to maximize staking yield and simplify the Ethereum staking process.
- The Frax Ether system consists of three primary components: Frax Ether (frxETH), Staked Frax Ether (sfrxETH), and the Frax ETH Minter.
- frxETH is a stablecoin loosely pegged to ETH, while sfrxETH is the version that accrues staking yield.
- Frax ETH Minter allows the exchange of ETH for frxETH, bringing ETH into the Frax ecosystem.
- ETH in the Frax ecosystem comes in two forms: frxETH and sfrxETH.
About Frax Finance – Frax Ether: Pioneering the Frontier of Decentralized Finance
Frax Ether is a pioneering, liquid ETH staking derivative that harnesses the full potential of the Frax Finance ecosystem to optimize staking yields and streamline the Ethereum staking process, providing a seamless, secure, and DeFi-native avenue for earning interest on ETH.
The Frax Ether ecosystem is comprised of three integral components: Frax Ether (frxETH), Staked Frax Ether (sfrxETH), and the Frax ETH Minter, which collectively form a harmonious trifecta.
frxETH serves as a stablecoin, loosely pegged to ETH, harnessing Frax’s proven expertise in stablecoins and seamlessly integrating ETH into the Frax ecosystem.
sfrxETH is a yield-accruing variant of frxETH. All profits generated by Frax Ether validators are distributed to sfrxETH holders. By exchanging frxETH for sfrxETH, one becomes eligible to receive staking yields, which are redeemable upon converting sfrxETH back to frxETH.
The Frax ETH Minter (frxETHMinter) facilitates the seamless exchange of ETH for frxETH, effectively integrating ETH into the Frax ecosystem. This process triggers the deployment of new validator nodes as needed, while concurrently minting an equivalent amount of frxETH corresponding to the ETH sent.
In the Frax ecosystem, Ether (ETH) exists in two distinct forms: frxETH, also known as Frax Ether, and sfrxETH, referred to as Staked Frax Ether.
frxETH functions as a stablecoin, loosely pegged to ETH, ensuring that 1 frxETH consistently represents 1 ETH, with the circulating supply of frxETH mirroring the amount of ETH within the Frax ETH ecosystem. When ETH is deposited into the frxETHMinter, a corresponding amount of frxETH is minted. It is essential to note that holding frxETH independently does not qualify for staking yield, and its utility is analogous to holding ETH itself.
sfrxETH is an ERC-4626 vault meticulously designed to accumulate the staking yield generated by Frax ETH validators. At any given time, users can seamlessly exchange their frxETH for sfrxETH by depositing it into the sfrxETH vault, thereby enabling them to earn staking yield on their frxETH holdings. Over time, as validators accrue staking yield, an equivalent amount of frxETH is minted and added to the vault, allowing users to redeem their sfrxETH for a greater amount of frxETH than they initially deposited. The exchange rate of frxETH per sfrxETH increases over time as staking rewards are added to the vault. By holding sfrxETH, you effectively hold a percentage claim on an increasing amount of the vault’s frxETH, with staking rewards distributed proportionally among sfrxETH holders based on their share of the total sfrxETH supply. This mechanism is reminiscent of other autocompounding tokens, such as Aave’s aUSDC and Compound’s cUSDC.
