Developer2 months ago$35–$50 hourlyFull-timeManhattan, New YorkWe are looking for an experienced game developer to build a standalone, provably fair betting module that integrates securely via API with our existing socifi platform.

Implement real-time price updates using Binance WebSocket API. Build a scalable WebSocket server to handle thousands of users. Implement betting logic (users place bets on live crypto prices). Ensure fair bet settlement based on final price at the end of each round. Implement provably fair gaming using cryptographic verification (e.g., SHA-256, Ethereum smart contracts, or Chainlink VRF). Validate user authentication Check & update player balances Store bet transactions & results in Back Office Ensure the game runs at maximum speed, even under high traffic loads. Optimize WebSocket connections to prevent lag & ensure ultra-low latency. Develop a React.js frontend matching our casino UI/UX. Ensure secure, fair, and high-performance game logic. Write clean, modular, and well-documented code.

Binance WebSocket API (Live Price Updates) Prices must be cached for instant access to reduce API latency. Provably Fair System (Blockchain / SHA-256 Hashing) Users must be able to verify the fairness of the game using cryptographic proof. The game seed must be hashed before the round starts, ensuring that results cannot be manipulated. If blockchain-based, use Layer 2 solutions (Polygon, Solana) for speed instead of Ethereum. Security & Protection Against Cheating Rate-limiting & bot detection must be implemented to prevent abuse. Game logic must be auditable & verifiable to ensure fairness. DDoS protection (Cloudflare/AWS WAF) must be in place to prevent attacks. Failover & Auto-Scaling Must deploy multiple WebSocket servers behind a load balancer.
