Project description:
"I’m building a fast-paced, real-time snake arena where dozens of players can join the same match from either an Android device or any modern browser. Low-latency play is critical—authoritative server logic, WebSocket/UDP networking, interpolation and prediction all need to be in place so movement feels as smooth as the original [login to view URL] even when the room is crowded.

Every round a player’s snake is tied to an Ethereum address. Sign-in, item ownership and post-match rewards must flow through Coinbase Wallet; the game should auto-detect the wallet, request a signature for login, and push ERC-20/ETH transactions for cosmetic purchases or prize payouts. Keep this wallet layer modular so we can drop in additional options later without rewriting core code.

Deliverables

* Android APK plus Play-Store–ready bundle
* Browser build hosted on a staging server
* Solidity contract (testnet first) covering score proofs, reward minting and basic in-game purchases
* Backend code and deployment guide for the authoritative multiplayer server
* Coinbase Wallet integration with clear documentation and unit tests
* Brief PDF with build steps, contract verification and go-live checklist

I’ll supply UI mock-ups and gameplay rules; you choose the engine (Unity, Godot, HTML5 + Node, etc.) that best meets the performance target. Clean, well-commented code in an active Git repo is expected. Once the prototype is up we’ll run a live play-test to confirm latency stays under 100 ms with 50 concurrent users. If you’ve shipped real-time multiplayer or blockchain titles before, let’s discuss timeline and milestones." (client-provided description)
