# Introduction to $RUSD

### **What is $RUSD?** 

$RUSD is the native decentralized stablecoin of the RealFI ecosystem, pegged 1:1 to the US Dollar. Unlike other stablecoins, the value of $RUSD is over-collateralized by a meticulously designed, diversified treasury of yield-generating assets. This treasury not only includes highly liquid on-chain assets from mature DeFi protocols on the BNB Chain (like Venus, Aave) but also innovatively incorporates over-collateralized, off-chain Real World Asset (RWA) loans, rigorously vetted through our RealFI Launchpad platform. This makes $RUSD not just a stable medium of exchange, but an engine of continuous value creation from its underlying assets.

### **The Dual-Token Model: $RUSD vs $sRUSD** 

To clearly separate the "transactional" and "savings" attributes of the stablecoin, we have designed a dual-token model:

* **$RUSD (RealFI USD):**
  * **Positioning:** A stable unit of account and medium of exchange.
  * **Value:** Its value is strictly pegged to approximately $1.00.
  * **Use Case:** Designed for transactions and payments, such as subscribing to assets on the Launchpad or being used as a base currency in other DeFi protocols. It does not generate interest itself, much like digital cash in your wallet.
* **$sRUSD (Staked/Savings RUSD):**
  * **Positioning:** The protocol's yield-bearing certificate and investment vehicle.
  * **Value:** Its value is not equal to $1.00. Instead, as the protocol's treasury continuously accumulates yield, its value relative to RUSD will consistently grow.
  * **Use Case:** Designed for earning real yield and long-term savings.

You can understand it this way: $RUSD is the dollar bill, while $sRUSD is a deposit receipt for a high-yield savings account that appreciates in value over time.
