Promise Protector

This project uses UMA's Optimistic Oracle to allow people to invest in whether they believe governments will reach their Carbon emission targets of 2030. It uses an Event-based Prediction Market, for instance, if someone believes Canada's 2030 carbon emissions will be 30% lower than 2022 levels then someone could hold a long token, until the expiry. They can do the NO query if someone believes emissions won't be lower than 30% by 2030.

It uses UMA's Optimistic Oracle to create an Event-based Prediction Market using a YES_OR_NO_QUERY to allow users to say Yes or No for the event of a certain event. UMA's protocol helped with creating an exchange where people can verify the truth after the event on a date like 'January 1st, 2023'. You can write to the contract and issue something like 10,000 tokens, and try to add different parameter information such as ancillaryData.
