Betinho

Betinho is a Telegram Mini App that revolutionizes the sports and entertainment betting experience by seamlessly integrating Web3 technology with the popular messaging platform. Our project aims to make sports betting more accessible, social, and engaging for both cryptocurrency enthusiasts and newcomers to the Web3 space.

Core Concept: Betinho transforms Telegram into a comprehensive sports betting platform, allowing users to place bets, follow live updates, and interact with other bettors without ever leaving the app. By leveraging Telegram's vast user base and familiar interface, we're bridging the gap between traditional messaging and decentralized betting applications.

Key Features:

1. Seamless Web3 Onboarding: Utilizes Web3Auth for a frictionless entry into the world of cryptocurrency betting. Users can log in using their existing Google accounts or other social login methods. Automatic wallet creation and management, eliminating the need for users to handle complex crypto wallets.

2. In-App Betting: A wide range of sports and entertainment events to bet on. Real-time odds updates and live event tracking.

3. News and Updates: Integrated sports news feed to keep users informed about the latest developments. Personalized notifications for favorite teams, players, and upcoming events.

4. Social Betting Experience: In-app chat functionality powered by XMTP for secure, decentralized messaging. Leaderboards to gamify the betting experience.

5. Technical Implementation: Built as a Telegram Mini App for seamless integration within the Telegram ecosystem. Utilizes the Chiliz blockchain for fast, low-cost transactions and token management. Implements Web3Auth for user authentication and wallet creation. Incorporates XMTP for decentralized, secure in-app messaging. Smart contracts deployed on the Chiliz Chain to manage bets, payouts, and user data. React-based frontend for an intuitive user interface.

6. User Experience: Betinho offers a streamlined user experience that combines the familiarity of Telegram with the excitement of sports betting. Users can easily navigate between chat conversations, betting interfaces, and news updates. The app's design focuses on simplicity, ensuring that even those new to cryptocurrency can participate without feeling overwhelmed by technical complexities.

7. Impact and Potential: By bringing Web3 sports betting to Telegram, Betinho has the potential to introduce millions of users to decentralized applications and cryptocurrency. It serves as a gateway for mainstream adoption of blockchain technology in the betting industry, offering increased transparency, security, and global accessibility.

Betinho represents the future of social sports betting, combining the best of Web3 technology with the convenience and reach of Telegram. It's not just a betting app; it's a community-driven platform that makes the excitement of sports wagering accessible to everyone, anywhere in the world.

How Betinho was built:

Telegram Mini App Framework: Developed using the Telegram Mini App SDK to create a seamless in-app experience. Utilized Vite(React) for building the user interface, ensuring a responsive and interactive design. Implemented TailwindCSS for rapid styling and consistent UI components.

Web3 Integration and Authentication: Leveraged Web3Auth for user onboarding and wallet creation. Implemented the Web3Auth PnP No Modal for a customized authentication flow. Integrated the OpenloginAdapter for social login capabilities, allowing users to authenticate with their Google accounts.

Blockchain Integration: Deployed smart contracts on the Chiliz Chain testnet (Spicy) for managing bets, user balances, and game logic. Utilized the Chiliz Chain's native CHZ token for all in-app transactions and betting activities. Implemented viem library for interacting with the Chiliz Chain, handling transactions, and reading contract states.

Backend Infrastructure: Developed a Node.js backend to handle off-chain logic, user data management, and serve as an intermediary between the frontend and blockchain. Utilized Nitro for creating RESTful APIs to handle betting logic, user profiles, and game management.

Real-time Communication: Integrated XMTP (Extensible Message Transport Protocol) for decentralized, secure in-app messaging. Implemented real-time updates for live odds, game scores, and betting results using broadcast.

Smart Contract Development: Wrote smart contracts in Solidity, focusing on gas optimization for the Chiliz Chain. Implemented a factory pattern for creating individual game contracts, allowing for scalable and isolated betting environments. Used OpenZeppelin libraries for standard token functionalities and security best practices.

Frontend State Management: Utilized React Context API for global state management, particularly for user authentication status and wallet information. Implemented custom hooks (e.g., useAuth) for encapsulating Web3Auth and blockchain interaction logic.

Faucet Implementation: Created a custom faucet smart contract on the Chiliz Chain testnet to distribute initial CHZ tokens to new users.

Testing and Deployment: Utilized Froundry for smart contract testing and deployment to the Chiliz Chain testnet.

By leveraging the power of Web3Auth for seamless onboarding, the speed and efficiency of the Chiliz Chain for transactions, and the security of XMTP for messaging, we've created a robust and user-friendly sports betting platform within Telegram. The combination of these technologies allows us to offer a unique, blockchain-powered betting experience that's accessible to both crypto-native users and newcomers alike.
