Su: A Revolutionary Money Protocol for the Sui Network

Introduction: Su is an innovative financial protocol developed for the Sui Network. It introduces a novel approach to stablecoins by decomposing the Sui coin into two distinct asset classes: Beta Coins and Leveraged Sui. This design aims to address key issues in stablecoin functionality, including volatility, scalability, and decentralization.

Core Components:

1. Beta Coins:

   • Fractional Sui: This coin has a beta of 0.1, meaning it is designed to track only 10% of Sui's volatility. It functions as a floating stablecoin, providing a less volatile investment compared to the underlying asset.

   • Sui Dollar: This is a stablecoin with a beta of 1, designed to maintain a stable value and provide reliability for transactions and DeFi activities.

2. Leveraged Sui:

   • This asset absorbs the remaining volatility that Beta Coins do not capture. By taking on this volatility, Leveraged Sui allows Beta Coins to maintain their stability while offering a perpetual contract without the risks associated with liquidations or funding rates.

Unique Features and Advantages:

• Capital Efficiency: Su's protocol is designed to be capital-efficient. Unlike traditional models that rely on over-collateralization to ensure the system's solvency, Su transfers volatility from risk-averse users to those willing to take on more risk. This approach avoids the need for excessive collateral and supports a more dynamic and scalable financial system.

• Scalability and Decentralization: Su addresses the stablecoin trilemma by balancing scalability, decentralization, and stability. Traditional stablecoins often sacrifice one of these aspects for the others. Su's design aims to offer a scalable and decentralized stablecoin solution while maintaining stability, thus unlocking new opportunities for DeFi markets.

Stablecoin Trilemma and Solutions:

• Types of Stablecoins:

  1. Cash Collateralized: These are fiat-backed tokens like USDT and USDC. They are highly stable but rely on centralized collateral.

  2. Asset-backed: These stablecoins are backed by tangible assets such as precious metals.

  3. Crypto Over-collateralized: Examples include MakerDAO’s DAI, which uses over-collateralized crypto reserves to maintain value.

  4. Algorithmic: These stablecoins use mechanisms like minting and burning to stabilize their value.

• Challenges:

  • Centralized solutions like USDT and USDC, while efficient, rely on external collateral and redemption mechanisms, posing risks in times of crisis.

  • Over-collateralized systems, such as CDPs, are capital inefficient, requiring users to maintain high collateral ratios.

  • Algorithmic stablecoins have struggled with stability and resilience, as seen in past failures.

Security Measures: Su prioritizes security with multiple layers of protection, including:

• Comprehensive unit test coverage.

• Formal verification tools.

• Security audits before deployment.

• Bug bounties and secure oracles.

• Upgradeable contracts for post-deployment fixes.

• Multi-signature wallets and time locks to protect against future changes.

Open Source Commitment: Su adheres to open-source principles, promoting transparency and trust. The open-source nature ensures that vulnerabilities can be quickly identified and addressed, fostering a collaborative development environment.

Interest Protocol CLAMM: The CLAMM (Concentrated Liquidity Automated Market Maker) is a decentralized exchange with several advanced features:

• Stable Curve: A bonding curve designed for correlated assets that combines constant product and constant sum invariants to provide a stable trading environment.

• Volatile Curve: Concentrates liquidity around the price of assets using internal oracles and exponential moving averages.

• Customizable Hooks: Allows pool deployers to implement custom computations for various actions such as swaps and liquidity changes.

• Public Good: Swap fees are controlled by the pool deployer, not Interest Protocol, making it a venue for projects to benefit from their own revenue.

• Passive Liquidity Management: CLAMM automatically manages liquidity, reducing the need for active involvement from liquidity providers.

• One-Sided Liquidity: Liquidity providers can contribute only one type of coin, simplifying the process.

• Multi-Coin Pools: Supports pools with more than two coins, allowing for diverse and concentrated trading pairs.

Su’s innovative approach addresses critical issues in stablecoin design, aiming to provide a more scalable, efficient, and secure solution for the DeFi ecosystem.
