Introducing Su: A Decentralized Money Protocol for Sui Network
Su is a revolutionary money protocol designed for the Sui Network, offering a new way to manage volatility and stablecoin creation. Built on a set of smart contracts, Su transforms Sui (SUI) coins into two distinct asset classes: Beta Coins and Leveraged Sui (xSui), providing users with stability or leverage depending on their risk preferences. The protocol allows for the creation of stablecoins and offers capital efficiency without requiring over-collateralization.
Beta Coins:
Sui Dollar (SD): A stablecoin with a beta of 1, pegged to the US Dollar, offering stability.
Fractional Sui (fSui): A "floating stablecoin" with a beta of 0.1, tracking 10% of Sui's price volatility, giving it low volatility but exposure to Sui's price movements.
Leveraged Sui (xSui): This asset absorbs the remaining volatility from Beta Coins, enabling users to take leveraged positions on Sui without liquidations or funding rates. It allows risk-seeking users to profit from price fluctuations.
The stablecoin market typically faces the trilemma of having to sacrifice decentralization, scalability, or stability. Centralized stablecoins (like USDT) offer scalability but at the cost of decentralization, while over-collateralized solutions (like DAI) sacrifice capital efficiency. Su aims to solve these issues by offering decentralized stablecoins (SD and fSui) without requiring over-collateralization, thanks to the volatility absorption by xSui.
Decentralized Stablecoins: SD and fSui are decentralized, free from reliance on off-chain assets, ensuring resilience against third-party risk.
Capital Efficiency: Unlike traditional stablecoin models, Su doesn’t require excessive collateral to maintain solvency. Instead, it transfers volatility to xSui users, allowing the system to remain liquid and capital-efficient.
Liquid Staking: Su stakes Sui collateral with validators, providing SD holders a higher APY than traditional savings options like U.S. T-Bills.
Su introduces a novel approach to creating decentralized, scalable, and stable assets on the Sui Network. By dividing Sui into Beta Coins and Leveraged Sui, the protocol provides both stability for risk-averse users and leverage for those seeking to profit from volatility, making it a promising solution for DeFi’s stablecoin challenges.
