MVP Smart Contract & Backend on Polygon (UMA Protocol)

PredictPiX is a decentralized prediction market platform where all user transactions are conducted using Pi Network's native currency. Users engage with the platform through the Pi Browser, and all prediction market logic, including creation, resolution, and settlement, is powered by smart contracts deployed on the Polygon network. UMA Protocol's Optimistic Oracle and LongShortPair contracts will be used to ensure secure, decentralized resolution, unless the selected developer has another option that they are more familiar with. We have no interest in AMMs or liquidity pools.

All blockchain gas fees are paid from a dedicated wallet owned by us, which is auto-funded via a % of platform fees.

Objective:
We are seeking a qualified blockchain developer to:
Deploy UMA's LongShortPair smart contracts and Optimistic Oracle on Polygon.
Integrate smart contract calls into our existing backend.
Implement backend wallet logic to pay Polygon gas fees from our owned wallet.
Ensure full alignment with Pi-only frontend logic (users never interact with Polygon or MATIC).

Scope of Work:

Smart Contract Work
Deploy and configure UMA LongShortPair and Oracle contracts on Polygon mainnet.
Create 2–3 example markets with testable endpoints for prediction and resolution.

Backend Integration
Modify existing backend to:
Translate Pi user actions into Polygon contract calls
Handle predictions, resolutions, and result retrievals
Connect to PI Network with wallet and transaction abilities through their SDK
Implement wallet gas fee automation (including tracking and auto-funding)

Testing & Deployment
Full testing with mocked and live Pi transactions
Documentation for admin and future devs

Optional (but preferred):
Security best practices for gas wallet protection
Transaction logging and error handling

Deliverables:
Deployed and verified contracts on Polygon mainnet
Updated backend codebase with contract interaction logic
Working front and backend integration
Gas wallet automation logic
Basic admin dashboard or CLI for market creation and resolution control
Deployment and testing documentation

Timeline:
Estimated completion: 3–4 weeks
Start date: ASAP
Budget: Open to proposals, but targeting $1,000 - 1,375 CAD for MVP build (milestone-based). We would like to offer partial payment in PI to interested Devs.
