Uvote

Inspiration Uvote is a decentralized prediction market platform built on blockchain technology. The project was inspired by the need to create a transparent, trustless system where creators can launch their own tokens and users can make predictions on various outcomes, all secured by smart contracts.

What it does Uvote allows users to:

Create creator tokens (ERC20) to build reputation and community Create prediction markets with multiple outcomes Bet on predictions using creator tokens Trade tokens on a decentralized exchange Participate in a governance system where token holders have voting power The platform operates on blockchain networks (Ethereum/Moonbeam) using smart contracts to ensure transparency and security.

How we built it The project was built using:

Smart Contracts: Solidity contracts for CreatorToken, CreatorTokenFactory, PredictionMarket, and TokenExchange using OpenZeppelin libraries Development Framework: Hardhat for contract development, testing, and deployment Frontend: React with TypeScript, using Vite as the build tool UI Components: Radix UI components with Tailwind CSS for styling Backend: Node.js with Express for API services Blockchain Integration: Ethers.js for wallet connections and contract interactions The system supports both local development (Hardhat network) and deployment to Moonbeam/Moonbase networks.

Challenges we ran into Key challenges included:

Managing complex contract interactions between multiple smart contracts Handling gas optimization for prediction market operations Implementing proper access control and permissions between contracts Creating a seamless user experience for wallet connections and transactions Ensuring proper token economics and exchange mechanisms Managing state synchronization between frontend and blockchain Accomplishments that we're proud of Successfully deployed a complete prediction market ecosystem Created a modular architecture with separate factories and exchanges Implemented creator token system with reputation mechanics Built a responsive and modern frontend interface Established proper contract deployment scripts for different networks Created comprehensive testing suite for smart contracts Implemented proper error handling and user feedback systems What we learned Deep understanding of DeFi mechanisms and token economics Advanced smart contract development patterns and best practices Frontend integration with blockchain technologies Importance of gas optimization and transaction management User experience considerations for Web3 applications Network deployment strategies and configuration management Security considerations in decentralized applications What's next for Uvote Planned future developments include:

Advanced Features: Creator verification systems, notification systems, advanced analytics UI/UX Improvements: Dark mode, mobile responsiveness, accessibility improvements Governance: On-chain governance system for platform decisions Staking: Staking mechanisms for creators and token holders Mobile Apps: Native iOS and Android applications External Integrations: Sports APIs, financial data providers, social media sharing Advanced Prediction Types: Multi-outcome predictions with weighted outcomes Caching and Performance: Redis caching for improved performance Email Notifications: Email alerts for prediction outcomes and important events Feedback submitted

Working on the business model to make this system profitable, we thought about doing it this way:
When a user buys tokens from a creator, the money is distributed as: 2% for the creator, 1% for the platform, and 97% to the liquidity reserve (ensuring users can always sell their tokens).
The 3% "loss" on entry isn't a real loss—it's the cost of entry. The real opportunity is in predictions: users can bet their tokens and, if they win, double or more their initial amount.
Example:
User puts in 100 DOT → receives tokens worth 97 DOT
Wins in predictions → now has tokens worth 194 DOT
Withdraws → receives ~192 DOT
Net profit: ~92 DOT
The 3% is the "entry ticket" to a system where you can multiply your investment by playing well in predictions.

This system is 100% functional and includes: Anti-fraud reporting system: if a creator publishes a prediction with false or manipulated results, users can report it. The system investigates and, if fraud is confirmed, automatically refunds all affected users. Penalties for fraudulent creators: creators who attempt to scam with fake predictions are penalized, thus protecting the ecosystem's integrity and user trust. Automatic price conversion: when a creator modifies their coin's price, the system performs the necessary conversions to maintain consistency in user balances. Token redemption for DOTs: users can redeem a creator's tokens for DOTs (the native currency) at any time, with guaranteed liquidity thanks to the reserve system.
