NFT Call options are created by using modified UMA Long Short Pair Library. After Minting the user will get a Long NFT (Call Option) and a Short NFT (Covered Call after selling Option).

Users can sell the NFT using any NFT marketplace such as opensea.io to collect premium.

After expiry users can settle and get the amount by depositing the corresponding NFT. The price of the long token will be (settlement price - strike price) / strike price. The short token will be 1 - price of long token.
