We are looking for an experienced blockchain developer or a small development team to build a streamlined event prediction market MVP within 4–6 weeks. The platform will leverage PI Network wallets exclusively for user deposits, withdrawals, and authentication, with backend processes executed efficiently using Polygon blockchain smart contracts.
Estimated Budget:
$2500 - $3,000 CAD (negotiable based on experience and proposal quality)
Scope of Work
The MVP must provide essential prediction market functionalities with a strong emphasis on simplicity, user-friendliness, and compliance:
Core Functionalities
Event Prediction Engine (Binary Outcomes) Users predict YES/NO outcomes on predefined events using PI. Events approved and managed via admin interface.
PI Network Wallet Integration Seamless deposit and withdrawal via PI Network Wallet. PI transactions managed securely off-chain until settlement.
Polygon Smart Contracts Simple, transparent smart contracts for outcome verification and PI settlement. Backend covers blockchain gas fees (no user-facing MATIC fees).
Admin Dashboard Interface for managing events, user disputes, and monitoring transactions. Admin approval required for event creation to ensure compliance.
Automated Market Settlement Settlement initiated automatically based on user consensus. Admin intervention for resolution disputes.
Technical Requirements Blockchain & Wallets: PI Network Wallet SDK, Polygon Blockchain (Solidity), Web3.js/Ethers.js Backend: Node.js or Python (FastAPI/Django), PostgreSQL/MongoDB Frontend: React.js/Vue.js compatible with PI Browser Open Source Usage: Preference for legally licensed or open-source libraries
Compliance and Regulation
The platform must adhere strictly to all applicable regulations and best practices regarding blockchain and prediction markets.
Explicit gambling terminology is to be avoided; use "event prediction" or "forecasting" instead.
Compensation & Partnership Options We offer flexible compensation structures: Milestone-based Payments Partial or full compensation in PI (optional) Opportunity for long-term partnership with a potential revenue-sharing model
We seek practical, efficient, and regulation-compliant solutions with an open and collaborative development approach. Interested developers or teams are encouraged to propose their preferred working arrangements and provide examples of relevant previous projects.
