Vyper Core works as a set of smart contract which can take any SPL token and a custom payoff function, and redistribute the tokens to match the payoff upon certain conditions. For example, people can deposit farming LP tokens, which after some time (e.g. a week) are redistributed to reflect the the impermanent loss vs fees generated.
There are three main smart contracts:
- Vyper Core: manages position IOUs creation and redemption, accepts only fungible tokens (e.g. LP tokens or cTokens). It redistributes collateral deposited consuming data from the rate calculator and redeem logic contracts
- Rate Calculator: updates the fair price of the collateral deposited (e.g. USD value of LP token). Supports up to 10 different underlyings for sophisticated payoffs
- Redeem Logic: payoff formula which specifies how collateral should be distributed, based on initial collateral deposited, initial prices, final prices, and other parameters (e.g. strike, duration)
