About

You must have experience integrating crypto currency into Unity based web game! Please share this past experience in your application. snakey.cash is a fast-paced, browser-based multiplayer snake game where players compete for real-money stakes, inspired by Slither.io. The snake gameplay itself is already solved—we’re using a proven Unity WebGL template that handles movement, collisions, boosting, bots, and cash-out triggers. Our focus now is transforming that template into a fully functioning crypto-powered platform: players will be able to deposit USDC, join live lobbies, compete, and cash out their winnings in a seamless, secure, and production-ready environment. Vision & Context Our goal is to create a lightweight, low-friction crypto gaming experience that feels as smooth as popular .io games but with a real financial layer. We’re not building a complex metaverse or an on-chain-only game; we’re delivering a fun, competitive skill-based experience where users can play instantly in their browser, stake small amounts, and withdraw earnings without friction. To achieve this, we need a rock-solid payment and ledgering system, admin tools for operational control, and production infrastructure that can scale. Project Scope • Integrate the pre-built Unity WebGL snake game into a Next.js (or similar) browser frontend • Implement real-time multiplayer lobbies and matchmaking using Socket.IO, Photon, or similar networking solutions (using the template’s hooks) • Develop crypto deposit and withdrawal flows using USDC on Ethereum, Base, Polygon, and Solana • Build a secure double-entry ledger system for tracking all user balances and game outcomes • Implement reconciliation and webhook/job systems for deposits, withdrawals, and treasury management • Create an admin dashboard to manage users, lobbies, balances, bans, and system health • Connect live leaderboards, friends, and referral systems to real game data • Add reconnect/resume logic tied to balances and cash-outs, plus mobile/touch optimisations • Set up production infrastructure: CI/CD pipeline, secrets management, monitoring/logging, rollback strategy, and staging environment Technical Requirements • Proven experience integrating crypto wallets and payment flows (particularly USDC across EVM and Solana chains) • Strong backend expertise with Node.js/Express and Socket.IO or Photon networking • Familiarity with Unity WebGL builds, multiplayer hooks, and browser deployment (no gameplay coding required) • Experience with modern frontends (Next.js preferred) and Firebase or equivalent authentication • Ability to design and implement secure financial flows and admin tooling • Experience with production-grade DevOps (Vercel, AWS, or similar) and monitoring/logging best practices • Strong communication skills, proactive problem-solving, and ability to deliver from a clear starting point Deliverables • Fully integrated crypto payments and double-entry ledger connected to the Unity game • Functional deposit/withdrawal flows with reconciliation and treasury tracking • Admin dashboard for live operations and player management • Multiplayer lobbies, live leaderboards, and friends/referral systems connected to actual game data • Mobile-friendly WebGL deployment with reconnect/cash-out logic • Production-ready backend and infrastructure with CI/CD, monitoring, and rollback capability • Documentation for setup, deployment, and ongoing maintenance Success Criteria The final product should feel indistinguishable from a polished .io game in terms of performance and UX, while running a secure, auditable financial layer underneath. Players should be able to open their browser, deposit USDC, join a match within seconds, and confidently withdraw winnings. Admins should have full visibility and control of the platform through dashboards and logs.
