# Senior Full-Stack Web3 Developer Needed (Solana + Mobile + Web) We are building a Web3 ecosystem around an existing YouTube animation brand with an active website and social media presence. The project revolves around a utility token on the Solana blockchain and a reward platform where users earn tokens through verified engagement. We are looking for an experienced full-stack developer (or a small team) who has successfully delivered blockchain-based applications before. ## Project Overview The ecosystem consists of four main components: ### 1. Solana Utility Token The utility token will be deployed on the Solana blockchain. Responsibilities include: * SPL Token creation * Smart contract/program development where required * Security best practices * Deployment on Solana Mainnet * Verification on Solana Explorer * Token mint authority and treasury management * Documentation The architecture should support future exchange listings (CEX and DEX). --- ### 2. Mobile Application (iOS & Android) Develop a modern mobile application with a clean UI. Features include: * User registration/login * User profiles * Secure wallet integration (please propose the most suitable architecture) * Token balance * Reward history * Referral system (optional but preferred) * Push notifications Users will complete engagement tasks such as: * Watching YouTube videos * Subscribing to our YouTube channel * Following our social media pages * Completing promotional campaigns The app must verify completed tasks before rewards are released. --- ### 3. YouTube Watch-to-Earn System One of the core features is a real user engagement reward system. Users should earn tokens based on actual watch time rather than simply opening a video. Please propose the best technical solution using available YouTube APIs together with your own verification methods. The system should include anti-fraud mechanisms such as: * Minimum watch duration * Watch progress validation * Daily earning limits * Bot detection * Device fingerprinting * Duplicate account detection * IP abuse protection * Suspicious activity monitoring Reward calculations should be configurable through the admin panel. --- ### 4. Website & Admin Dashboard Develop a responsive website that mirrors the mobile app. Features include: * Registration/Login * User profiles * Wallet dashboard * Token balances * Task center * Reward history * Referral dashboard * Admin CMS * User management * Reward management * Campaign management * Analytics dashboard The website and mobile app must stay synchronized in real time. --- ## Backend Requirements Please recommend the best stack. Scalable cloud architecture is expected. Examples: * Node.js / NestJS * PostgreSQL * Redis * Docker * WebSockets * REST API / GraphQL Cloud deployment experience is preferred (AWS, Google Cloud, Azure, etc.). --- ## Security Requirements Security is extremely important. The solution should include: * Secure authentication * Wallet security * Rate limiting * Anti-bot protection * API security * Smart contract best practices * Code documentation --- ## Deliverables * Complete source code * Smart contracts/programs * Mobile applications * Responsive website * Backend APIs * Admin dashboard * Deployment documentation * Technical documentation --- ## Acceptance Criteria * Solana token successfully deployed on Mainnet. * Mobile applications successfully published on the Apple App Store and Google Play. * Responsive website fully operational. * Wallet balances synchronized across web and mobile. * Reward engine functioning reliably. * Admin dashboard fully operational. * Clean, documented, maintainable source code. --- ## Please Include With Your Proposal * Portfolio of similar Web3 projects * Solana experience * Mobile apps you've built * Smart contract experience * Estimated timeline * Estimated budget * Recommended technology stack We're looking for a long-term development partner, not just someone to complete a one-time project.

You’ve got a complex ecosystem to build, and the key will be tight integration between blockchain, mobile, and web parts while keeping real-time wallet sync and instant rewards. For the blockchain coin, I’d suggest using Binance Smart Chain or Polygon—they offer cost-effective gas fees and broad wallet support. From past projects, I’ve created and audited BEP-20/ERC-20 tokens with seamless swap features. Have you considered using a layer-2 solution for faster on-chain confirmations needed for instant rewards? The mobile app’s wallet and task flow should be lightweight but secure. Using React Native with wallet connect and third-party identity verification worked well on a similar social rewards app I built. For payment, direct fiat integration via Stripe or MoonPay can accelerate onboarding and reduce friction. On the web side, a React frontend with real-time wallet sync via WebSocket and backend event listeners ensures balances update instantly. I’ve scaled apps to 10k concurrent users with auto claim functionality on task completion. Once APIs and UI assets are shared, I can outline a detailed tech stack and a 12-week timeline covering smart contract dev, audit, then app/web delivery. Ready to start designing a solution that hits all the marks for security, speed, and scale.
