Novel DeFi on Sui

Su (Alpha)

Su is a DeFi application designed to mint and burn coins backed by Sui with different beta values. It issues two coins:

• fSui - It has a beta of 0.1. When the Sui USD price goes up by 1 USD, fSui goes up by 0.1 USD.
• xSui - It has a variable beta value. It absorbs the price volatility of fSui to ensure it keeps a beta of 0.1.
