We are building an MVP for a prediction market platform designed for the Pi Network community. Users will access the platform through the Pi Browser and place predictions using Pi Network’s native coin (Pi).
All the actual market logic—creating markets, placing predictions, resolving results—will run on the Polygon blockchain. We will be using UMA Protocol (LongShortPair and Optimistic Oracle) to ensure secure and transparent resolution, but users will never interact directly with Polygon or need MATIC; everything is handled by the backend.
We need an experienced blockchain developer to help us complete the MVP by:
Deploying UMA contracts on Polygon (testnet first, then mainnet).
Connecting the backend so Pi user actions are processed on Polygon automatically.
Setting up a secure gas wallet to handle Polygon transaction fees.
Running full end-to-end testing with live Pi transactions.
Providing basic documentation for future updates.
If you have experience with Polygon smart contracts and backend integration, and ideally have worked with UMA Protocol or similar Oracle-based prediction markets, we’d love to hear from you.
