Wallet-based user registration (BSC Testnet only)
Automatic network detection & switching
Supabase-backed user management
Automatic virtual card generation (Bronze / Silver / Gold)
Token staking system with transaction logging
Referral system with rewards tracking
Dashboard with analytics & history
X (Twitter) OAuth integration
Discord bot with XP & invite tracking
A detailed README and database schema are already prepared.
 
✅ Responsibilities
 
You will be responsible for:
 
Completing and stabilizing the Next.js App Router implementation
Finalizing wallet connection & network enforcement (Chain ID 97)
Ensuring Supabase RLS policies are correct and secure
Implementing or completing:
Staking flows (stake, unstake, claim, emergency withdraw)
Referral tracking & reward logic
Dashboard analytics & transaction history
Finalizing X (Twitter) OAuth integration
Reviewing and improving overall code quality & structure
Fixing bugs, edge cases, and UX issues
Preparing the app for Railway deployment
(Bonus) Improving performance and Web3 UX
 
🛠 Tech Stack (Must-Have Experience)
 
Required:
 
Next.js 14/15 (App Router)
TypeScript
Wagmi v2 + WalletConnect
EVM chains (BSC preferred)
Supabase (Postgres, RLS, triggers, SQL functions)
Tailwind CSS
Web3 transaction handling & logging
 
Nice to Have:
 
Discord bot development (Node.js)
OAuth 2.0 (X / Twitter)
Smart contract interaction (staking contracts)
Framer Motion
shadcn/ui / Radix UI
 
🔒 Security Expectations
 
You must be comfortable with:
Wallet validation & chain enforcement
Preventing self-referrals & abuse
Transaction hash uniqueness checks
Secure handling of OAuth tokens
Supabase RLS & role-based access
 
📦 Deliverables
 
Fully working, deployable application
Clean, documented codebase
Verified Supabase schema & policies
Functional staking & referral systems
Deployment-ready build (Railway)
Basic handover documentation
 
⏳ Timeline
 
Estimated duration: 2–4 months
Start: Immediately
Potential for long-term collaboration
 
💰 Budget
 
Open to fixed-price or hourly
Please include:
 
Your estimated timeline
Relevant Web3 / Next.js projects
Any questions or suggestions to improve the system
 
🧠 How to Apply
 
When applying, please answer:
 
Have you built production Web3 apps with Next.js + Wagmi before?
Have you worked with Supabase RLS & SQL triggers?
Share 1–3 relevant projects (GitHub or live links)
What risks or improvements do you see in this architecture?
Generic proposals will be ignored.

I am seeking a world-class Systems Engineer / Rust Architect to build a proprietary asset extraction engine on the Solana network. This is not a "Web3 App" or a "DEX UI." This is a purely backend, low-latency machine designed to capture micro-value from market volatility.​The system mimics a "digital sluice," using high-precision math to harvest fractional differences that standard rounded-math bots ignore. We are scaling from a prototype to a 30-node distributed network managing 100+ concurrent execution "hands."​Core Technical Requirements​Low-Level Rust Mastery: You must be an expert in the Tokio runtime, asynchronous programming, and memory-safe mathematical operations.​Solana Network Physics: Deep understanding of the Sealevel runtime, custom WebSocket/Lumen bridges, and avoiding gRPC bottlenecks.​Jito & MEV Optimization: Proven experience with Jito Bundles, transaction shredding, and tip-optimization to ensure first-block inclusion.​Distributed Orchestration: Ability to architect a master-node system that manages 30+ regional nodes with seamless failover and zero-loss state management.​Precision Math: All logic must operate on u64 integers (Lamports) to avoid floating-point rounding errors. We do not "round" to the dollar; we capture the 9th decimal.​Key Responsibilities​Engine Hardening: Audit and optimize the core Rust logic for 0-latency execution.​Node Orchestration: Build the "Master Switch" to deploy, monitor, and update 30 nodes across global regions simultaneously.​The "Tax" Logic: Implement a secure, automated "sweeper" protocol that collects fractional value from all child-nodes into a master treasury without interrupting execution.​Redundancy: Ensure the system is "Anti-Fragile"—if a validator or node fails, the 50-drop safety protocol must trigger an instant failover.

Create intuitive, responsive user interfaces that deliver exceptional user experiences across our platform. You'll transform designs into pixel-perfect, performant applications while ensuring smooth interactions and real-time data visualization. We're looking for developers who are passionate about user experience, have an eye for design details, and can build complex web applications that handle large datasets efficiently while maintaining responsive, accessible interfaces across all devices and browsers.
Responsibilities:
Build responsive, performant web applications
Implement designs with attention to UX detail
Integrate with backend APIs and manage application state
Ensure cross-browser compatibility and accessibility

Build and maintain infrastructure for quantitative research and trading systems, bridging the gap between research and production. You'll work at the intersection of software engineering and quantitative finance, building high-performance systems for backtesting, simulation, and live trading. This role requires strong programming skills, understanding of financial markets, and the ability to translate complex mathematical models into reliable, production-ready code that executes strategies in real-time with minimal latency.
Responsibilities:
Develop backtesting frameworks and research tools
Implement trading algorithms and execution systems
Optimize code for performance and low latency
Collaborate with researchers to productionize strategies
