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
