Overview

A peer-to-peer sports betting platform developed over 3 months that enables users to participate in decentralized sports betting using any cryptocurrency. The project aimed to create a transparent, secure, and anonymous betting system where users could either create bets for others to accept (bet-to-grab) or direct bets with specific users (bet-to-friend). The platform integrates with Chainlink oracles for real-time sports data and Uniswap for token swaps, with all bets being converted and held in USDC to maintain value stability.

Process

The development began with designing the smart contract architecture, establishing the core betting logic and multi-token support system. Next, we integrated Chainlink oracles for both price feeds and sports data, ensuring reliable match outcomes and token conversion rates. We then implemented the Uniswap integration for seamless token swaps. The frontend was developed to provide real-time match feeds and an intuitive betting interface. Finally, we implemented the anonymity features and automated payout systems. Throughout the development, we conducted extensive testing on Ethereum testnet to ensure security and reliability.

Challenges

Key challenges included ensuring fair and transparent betting while maintaining user anonymity on the blockchain. Managing multiple cryptocurrency payments and converting them to USDC required complex integration with Uniswap and careful handling of slippage. Real-time sports data reliability was crucial, necessitating robust oracle implementations. Additionally, gas optimization for smart contracts was essential to keep transaction costs reasonable for users. The anonymous betting system needed to be both secure and user-friendly, which required innovative solutions in the smart contract design.

Result

Successfully delivered a functional MVP that demonstrated secure, anonymous betting capabilities using any cryptocurrency. The platform effectively handled multi-token support through Uniswap integration, real-time sports data through Chainlink oracles, and automated winner payouts. The system maintained bet anonymity while ensuring transparency in outcomes and payouts. The smart contract architecture proved efficient in gas usage and secure in handling user funds, creating a validated proof of concept ready for further scaling.
