# Collateralisation Polynomial Earn will be the first ever option vaults to implement partial collateralization. Partial collateralization will allow us to sell 1 call option with less than 1 underlying asset as collateral. Similarly, we'll be able to sell put options with less than the strike price worth of sUSD as collateral. The collateralisation ratio ranges from .8 to 1 according to the strategy. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
