O

This repository contains contracts used to resolve Polymarket prediction markets via UMA's optimistic oracle.

Architecture

The Adapter is an oracle to Conditional Tokens Framework(CTF) conditions, which Polymarket prediction markets are based on.

It fetches resolution data from UMA's Optmistic Oracle and resolves the condition based on said resolution data.

When a new market is deployed, it is initialized, meaning:
1) The market's parameters(ancillary data, request timestamp, reward token, reward, etc) are stored onchain
2) The market is prepared on the CTF contract
3) A resolution data request is sent out to the Optimistic Oracle

UMA Proposers will then respond to the request and fetch resolution data offchain. If the resolution data is not disputed, the data will be a to the Adapter after a defined li period(currently about 2 hours).

The first time a request is disputed, the market is automatically reset, meaning, a new Optimistic Oracle request is sent out. This ensures that *ob incorrect disputes do not slow down resolution of the market*.

If the request is disputed again, this indicates a more fundamental disagreement among proposers and the Optimistic Oracle falls back to UMA's DVM to come to agreement. The DVM will return data after a 48 - 72 hour period.

After resolution data is a, anyone can call resolve which resolves the market using the resolution data.
