Introducing Sauce, StableSwap Feature on Ref


  • Minimise volatility
  • Trade and save
  • Earn interest

Problem and solution

Figure 1: Comparison of StableSwap invariant with Uniswap (constant-product) and constant price invariants. The portfolio consists of coins X and Y which have the “ideal” price of 1.0. There are x = 5 and y = 5 coins loaded up initially. As x decreases, y increases, and the price is the derivative dy/dx. — [5]
  • D is the invariant
  • A is a coherent factor, which is set to 240 (can be adjusted by the DAO)
  • n is the number of stable tokens
