Technical details

Seller

When a user sells options into the pool, an ERC721 will be minted for the user to record the share of the liquidity they provided. This is used to keep track of the rewards and premiums when a buyer uses the liquidity.

Buyer

When a user buys options, an ERC20 option token is minted for the user. At expiration, they will be able to use the ERC20 option token to settle their position if it's in the money.
