f(x) Protocol fxUSDPrice

(FXUSD)

fxUSD is a decentralized, scalable stablecoin pegged to the US Dollar. It is created by 'decomposing' yield-bearing assets, such as staked Ethereum (stETH), into two distinct parts: a stable component, which is fxUSD itself, and a leveraged component called xPOSITION. It stands out by being 100% over-collateralized by high-quality, exogenous DeFi assets like wrapped staked Ethereum (wstETH) and Wrapped Bitcoin (WBTC), a design choice that explicitly differentiates it from algorithmic stablecoins.

No, fxUSD is explicitly not an algorithmic stablecoin. This is the most frequently asked question, often due to past events in the DeFi space. fxUSD is rigorously 100% over-collateralized by high-quality, exogenous DeFi assets such as wstETH (Lido) and WBTC. Its stability and peg to the US Dollar are maintained through a robust, multi-layered mechanism. This includes a Stability Pool, automatic rebalancing, redemption functionalities, and funding fees, all working in concert to absorb volatility and protect the fxUSD peg.

The yield for fxUSD is considered 'real yield' and originates organically from four primary sources. Firstly, the underlying collateral, such as staked Ethereum (stETH), continuously earns Ethereum staking rewards. Secondly, the protocol generates trading fees from users opening and closing leveraged xPOSITIONS. Thirdly, Stability Fees are paid by leverage traders to the Stability Pool during specific market conditions. Finally, FXN emissions provide native protocol rewards, which are distributed to various pool participants, ensuring a diversified and sustainable yield generation strategy.

The 'Liquidation Brake' is a unique rebalancing mechanism within the f(x) Protocol, designed to protect users from the severe outcomes of traditional hard liquidations. Unlike typical perpetual futures where users can lose 100% of their position, the Liquidation Brake prevents this for xPOSITION holders. Instead, the protocol automatically 'rebalances' a user's leverage by burning a certain amount of fxUSD from the Stability Pool. This action pays down a portion of the user's debt, effectively resetting their leverage to a safer level without forcing a complete loss of their position.

The $FXN token is the native governance token of the f(x) Protocol. Holders can lock their FXN to obtain veFXN, which grants significant utility and benefits. These benefits include the ability to vote on which liquidity pools receive higher rewards through a gauge system, capturing a substantial 75% of the protocol's generated revenue, and boosting their own yields in the Stability Pools by up to 2.5 times. This mechanism aligns incentives, decentralizes control, and rewards active participation in the ecosystem.

V1 of the f(x) Protocol focused on 'Stable-Leverage Pairs,' splitting a single token into two components, exemplified by fETH and xETH. V2 represents a major evolution, introducing the concept of xPOSITION. This allows for more flexible collateral types and offers fixed leverage options up to 10x. V2 also integrated flashloan-assisted leverage and established fxUSD as an omni-stablecoin, backed by multiple sub-pools. This design provides greater versatility, robustness, and enhanced capital efficiency by isolating risks across different collateral classes, making the system more adaptable and secure.
