SSS Bali Raffle Platform

Created a specialized web application for SuperlativeSS (SSS) NFT holders, offering an exclusive opportunity to win an all-expenses-paid trip to Bali through a transparent, multi-phase raffle process. The platform features a three-phase raffle system using Chainlink VRF for verifiable randomization, an ERC-721 NFT Pass system for prize redemption, and a modern React/Next.js frontend for a seamless user experience. The SSS Bali Raffle integrates blockchain technology with a modern web interface, ensuring both transparency and user-friendliness. The multi-phase raffle system strategically reveals winning attributes over time, driving engagement and allowing participants to acquire potentially winning tokens. The project showcases innovative use of smart contracts and decentralized oracles to create a fair and transparent prize system for NFT communities.
