The problem Decentralized Derivatives solves

1.The Platform is American Options based Platform to Purchase and Sell XTZ Call Options.
2.Underlying Asset used for the settlement is XTZ.
3.Call Option Sellers would also be receiving Staking Rewards since Tezos is Liquid Proof-of-Stake Blockchain.
4.OrO Oracle would be updating the XTZ/USD Pair price every 1 hour.

writeXTZ is the LP Token for the Pool to represent one's share in the Automated Market Maker Option Contract.
The Pool contract would be fetching price of XTZ/USD pair on the Purchase and Exercise of Call Options.
