What is f(x) rUSD (RUSD)?
The f(x) Protocol, developed by AladdinDAO, is a decentralized finance project that introduces a unique approach to stablecoins and leveraged trading. A key asset within this ecosystem is rUSD, a decentralized stablecoin designed to maintain a one-to-one peg with the US Dollar. It is a specialized version of the protocols flagship stablecoin mechanism, specifically tailored to utilize Liquid Restaking Tokens as its underlying collateral. The core functionality of rUSD relies on a volatility splitting mechanism. When users deposit collateral into the protocol, the asset is divided into two distinct components: a low-volatility stable asset and a high-volatility leveraged asset. In this system, rUSD represents the stable portion, while the leveraged side allows other users to gain amplified exposure to the price movements of the underlying collateral. This structure is intended to create a capital-efficient stablecoin that is fully backed by on-chain assets. While the protocol's primary stablecoin, fxUSD, typically uses Liquid Staking Tokens like staked Ether, rUSD specifically focuses on Liquid Restaking Tokens such as eETH from Ether.fi or ezETH from Renzo. By using these restaked assets as collateral, rUSD allows participants to benefit from the yields and incentives associated with the restaking ecosystem while holding a stable asset. Users can interact with rUSD in several ways. They can mint the token by depositing accepted collateral, or they can participate in the Stability Pool. The Stability Pool is a critical component of the protocol that ensures solvency by acting as a liquidity source for liquidations. Those who provide rUSD to this pool earn rewards derived from protocol revenue and emissions. Additionally, the project features arUSD, which is an auto-compounding version of rUSD that automatically reinvests gains for the user. Governance within the protocol is handled through a vote-escrow system. By locking tokens, users receive voting power that allows them to participate in decision-making processes, such as determining the allocation of protocol emissions and influencing the future direction of the platform. The project is built on the Ethereum network and focuses on providing a decentralized alternative to centralized stablecoins by leveraging the security and yield-generating potential of the Ethereum staking and restaking markets.

f(x) rUSD (RUSD) FAQ
rUSD is a decentralized stablecoin within the f(x) ecosystem that is specifically backed by Liquid Restaking Tokens (LRTs). It allows users to earn restaking yields and ecosystem points while holding a stable asset. In contrast, fxUSD is the protocol's flagship stablecoin, primarily backed by liquid staking tokens. While rUSD focuses on the restaking market, fxUSD is designed for broader liquidity and integration into newer leverage modules within the ecosystem.
No, rUSD is not an algorithmic stablecoin. It is a fully collateralized, and often over-collateralized, asset. It utilizes a specific mathematical invariant to split the volatility of the underlying collateral. This mechanism separates the asset into two parts: rUSD represents the low-volatility "stable" portion, while associated leverage tokens capture the high-volatility movements of the underlying collateral.
rUSD is the standard stablecoin which requires users to manually stake it in a Stability Pool to earn rewards. arUSD is the auto-compounding version of the token. It is designed for a "set-and-forget" experience, automatically reinvesting rewards and accruing points for the user. While rUSD is highly liquid and suitable for active trading, arUSD is tailored for passive yield seekers who want automated reward aggregation.
By using rUSD in the Stability Pool or through arUSD, users can simultaneously earn multiple layers of rewards. These include protocol-specific points, loyalty points from the underlying restaking providers, and EigenLayer points. Additionally, the protocol frequently runs campaigns where a portion of the native token supply is distributed to users who accumulate these points through the stablecoin pools.
Since rUSD is backed by Liquid Restaking Tokens, a significant de-peg of the underlying collateral could impact the collateral ratio. However, the protocol utilizes stability and liquidation triggers to protect the peg. If you simply hold rUSD, you are not at risk of liquidation. If you stake rUSD in the Stability Pool, your balance may be used to buy back liquidated collateral at a discount, which could decrease your rUSD balance while increasing your holdings of the underlying collateral.
Users can mint rUSD by depositing accepted Liquid Restaking Tokens into the protocol's official platform. It can also be acquired through supported decentralized exchanges and trading platforms. Currently, rUSD is native to the Ethereum Mainnet, which hosts the primary liquidity and point-earning mechanisms. The staking yield is variable, consisting of native restaking yields, protocol emissions, and potential gains from liquidation events.
