ETHWaterloo Hackathon 2019 submission: https://devpost.com/software/muh-options
Note on tickers: poETH = put-option-ETH for example.
A peer-to-peer call and put options on Ethereum powered by UMA and 0x. Generally the user interacts with an issuance and/or and exchange interface. In Issuance page, the user can create a "put" or "call" option on any finance asset that can have a price feed. For example, Alice can create an option that says "I would like to have the option to buy ETH at $200 6 months from now". That option is a tokenized derivative (ERC20) that automatically gets listed on the DEX: the exchange interface (DEX = decentralized exchange). A counterparty can see that "option" and satify it, for a fee of course. So the counterparty "buys" that option, effectively earning a fee while pledging to deliver the ETH to Alice 6 months from now.
A "put" option is the reverse: Alice buys the option to sell an asset at some point in the future.
