Description

Experience Level: Expert
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.

Estimated Duration: 3–4 weeks
Start Date: Immediate
Budget: $1,250–$1,500 CAD (milestone-based)

Please share your experience, similar projects you’ve worked on, and your estimated cost and timeline.

    Hi Tommy! How are you?

    Thanks for your job posting and I have some questions for your project.

    Have you deployed UMA’s LongShortPair and Optimistic Oracle contracts on Polygon before? If so, how did you configure them?

    How would you automate Pi user actions (e.g., placing predictions) to trigger Polygon smart contract functions from the backend?

    What’s your approach for securely managing a gas wallet that handles MATIC fees for backend-triggered transactions?

    I would like to discuss in more details with you.

    Best regards.

    Zack

    Hi Tommy,
    Do you already have a backend system in place to authenticate Pi users and manage their prediction actions, or would you need help setting that up as well?

    For deploying UMA on testnet/mainnet, do you have the specific market parameters (collateral type, expiry, price identifier, etc.) finalized, or will you need assistance defining those configurations?
