Blockchain Game Developer for 1v1 Project
Budget: €3,000 – €5,000 EUR
Description:
We are looking for an experienced developer with both blockchain and full-stack skills to complete a competitive 1v1 game project built on Polygon mainnet.
The project already includes a verified escrow smart contract, and we need integration with the rest of the platform:
Frontend: Next.js + Tailwind + wallet integration (RainbowKit/Wagmi).
Backend: Node.js (Express), WebSocket (real-time), Redis (matchmaking and game state).
Smart contract: escrow handling, configurable fee, automated winner payouts.
User flow:
login with wallet,
join matchmaking queue,
play on a real-time map (grid system),
when the match ends, the system determines the winner and executes payout through the smart contract.
Technical requirements:
Experience with Web3.js/Ethers.js and Solidity smart contracts.
Strong knowledge of Next.js and React.
Experience with WebSocket/Socket.io for real-time multiplayer systems.
Redis and queue/matchmaking systems.
Server deployment skills (Ubuntu + Nginx + Docker).
Goal:
Deliver a working MVP (login → matchmaking → real-time game → payout).
Duration:
Initial collaboration 1–2 months with possibility of extension.
Note:
Detailed game mechanics and design will be shared privately after selection, for confidentiality.
