Case Study: Raffle Maniac

Overview

Raffle Maniac is a decentralized raffle platform built to redefine transparency, automation, and fairness in online prize draws. Designed and developed by Performix Business Services, the platform enables creators to launch verifiable raffles on-chain using NFT-based tickets and Chainlink-powered randomness.

Performix led the full-cycle development, encompassing smart contracts, automation logic, UX design, and operational readiness for mainnet deployment. The result: a secure, scalable, and provably fair platform ideal for community giveaways, brand activations, and reward-based campaigns.

Project Objectives

Performix was tasked with building a raffle ecosystem that:

• Eliminates bias through verifiable randomness (Chainlink VRF)
• Enables creators to launch raffles independently with transparent rules
• Supports automated winner selection and payout
• Delivers NFT-based ticket ownership and on-chain traceability
• Maintains audit-ready security and financial isolation between raffles
  
  

Core Architecture

Smart Contract Layer

• Raffle Engine (Raffle.sol)
  Handles ERC-721 NFT ticketing, ticket validation, prize pool accounting, winner selection, and payouts. Includes full reentrancy protection and configurable safety mechanisms.
  
  
• Factory Contract (RaffleFactory.sol)
  Deploys new raffles with constraints (e.g., one active raffle per creator), enforces minimum ticket prices, and applies a creation fee. Maintains systemic control and consistency.
  
  
• Chainlink VRF & Automation
  
  
  
  • VRF (Verifiable Random Function): Generates tamper-proof randomness for winner selection.
    
    
  • Automation: Periodically scans raffles to trigger draws, handle payouts, and reclaim unclaimed prizes without manual input.

Technical Features

UX & Platform Design

Performix emphasized a clean, intuitive UX to make blockchain interaction seamless for non-technical users.

‍

Key Screens

• Create Raffle: Intuitive form for setup with progress indicators and input validation.

• Overview Gallery: Searchable list of active and ended raffles with real-time prize pools.

‍

• Profile Page: Displays raffles created, tickets owned, and transaction links.

‍

• Admin Dashboard: Manages factory settings, system fees, and manual draw triggers.

• Wallet Connection: Secure entry point via MetaMask or WalletConnect with chain guidance.
  
  

Design Principles

• Glassmorphism UI for a polished Web3 aesthetic
  
  
• Auto-save for drafts and fault-tolerant session recovery
  
  
• Guided onboarding for wallet and gas fee understanding
  
  

Security & Fairness Framework

Performix implemented multiple layers of trust:

• On-chain Prize Pool Isolation: Only winner payouts are authorized.
  
  
• Verifiable Randomness: Chainlink VRF ensures immutable, unbiased results.
  
  
• Fail-safe Recovery: If automation fails, winners can claim manually within the claim window.
  
  
• Operational Safeguards: Multi-sig controls for factory parameters and fee withdrawals.
  
  

Deployment & Readiness

Performix ensured full deployment integrity through the following steps:

1. Deploy Raffle.sol and RaffleFactory.sol
   
   
2. Configure Chainlink VRF (coordinator, subscription ID, gas, key hash)
   
   
3. Fund contracts with LINK for randomness and upkeep
   
   
4. Register Chainlink Automation (150k–250k gas limit)
   
   
5. Seed and verify test raffles end-to-end
   
   
6. Integrate frontend UI with live contract events and admin APIs
   
   

The system passed comprehensive unit and integration testing using Hardhat, covering:

• Ticket sales and bulk purchase validation
• Refund and emergency pause handling
• Automation flows for draw, payout, and prize reclamation

‍

Impact & Outcomes

Through this project, Performix demonstrated its ability to deliver enterprise-grade blockchain solutions with real-world usability.
Key achievements include:

• A fully decentralized raffle platform ready for production deployment
• End-to-end automation with minimal operational overhead
• Transparent and fair randomness powered by Chainlink
• Secure smart contract architecture with modular upgradability
• User experience tailored for both Web3 natives and newcomers
  
  

Conclusion

The Raffle Maniac project showcases Performix’s expertise in bridging blockchain engineering and user-centric design.
By combining audited smart contracts, secure automation, and a refined UX, Performix successfully delivered a platform that embodies trust, transparency, and technological sophistication — setting a new benchmark for fair digital raffles.
