Web3 Game Completion - Multiplayer & Token Integration

Project: Web3 Browser Game with Real-Time Multiplayer and Token Gating

Prototype: available on request
Part of the backend is already implemented, including wallet auth, token verification, socket connection, and base game loop integration. Below is a list of completed commits:

❗ What Needs to Be Done
A browser-based Web3 multiplayer game is in development. The core WebGL graphics engine is mostly ready, and now we need to complete the server-side logic, including player handling, prize spawning, token balance validation, and real-time communication.

? Game Mechanics
Runs in browser and Warpcast Frame (v2)

Only token X holders (ERC20, BASE chain) can play

Login via Metamask or Warpcast

Players move around an infinite map and see each other in real time

Player parameters (speed, size, vision) depend on token balance

Prizes appear randomly on the map — first player to reach it gets a claim link

? Backend Tasks
Check token balance (on Ethereum BASE)

Fetch user avatar from Warpcast → resize → upload to S3

Accept player coordinates, validate movement speed (anti-cheat)

Detect and filter duplicate sessions

Return visible players and their data (via WebSocket)

Emit new_prize when a prize spawns

Emit got_prize when a prize is successfully claimed

Admin API to spawn prizes

Store players and prizes in a database

Scalable architecture to support 10,000 users online

Data Structures:

// Prize
{
"x": int,
"y": int,
"id": string,
"custom_data": {...}
}
? Frontend (Partially Ready)
WebGL graphics already implemented in artwork.js

Socket connection initialized in onCompile()

All client-server sync logic happens inside updateCanvas() at 60 FPS

Player coordinates: this.par.Posx, this.par.Posy

? Tech Stack
Current prototype uses Python (server.py)

Open to switching to Node.js, FastAPI, or other performant frameworks

WebSocket + Ethereum Base + Warpcast Frames v2 integration is required

DB: PostgreSQL, Redis, or equivalent

File storage: S3 or similar

? Expected Deliverables
Full backend logic with API + WebSocket

Token validation and real-time coordination

Data exchange with frontend (players, prizes)

Admin endpoint for prize spawn

Deployment instructions

? Timeline & Budget
Start: ASAP

Budget: Open to fixed price or hourly — please include your estimate

Priority: clean, scalable, and stable architecture
