MVP Smart Contract & Backend on Polygon (UMA Protocol)

详细信息

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 WorkDeploy and configure UMA LongShortPair and Oracle contracts on Polygon mainnet.Create 2–3 example markets with testable endpoints for prediction and resolution.
Backend IntegrationModify existing backend to:Translate Pi user actions into Polygon contract callsHandle predictions, resolutions, and result retrievalsConnect to PI Network with wallet and transaction abilities through their SDKImplement wallet gas fee automation (including tracking and auto-funding)
Testing & DeploymentFull testing with mocked and live Pi transactionsDocumentation for admin and future devs
Optional (but preferred):Security best practices for gas wallet protectionTransaction logging and error handling
Deliverables:Deployed and verified contracts on Polygon mainnetUpdated backend codebase with contract interaction logicWorking front and backend integrationGas wallet automation logicBasic admin dashboard or CLI for market creation and resolution controlDeployment and testing documentation
Timeline:Estimated completion: 3–4 weeksStart date: ASAPBudget: 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.
