This application facilitates NFT giveaways. Users can connect their wallets, enter a giveaway, spin a slot machine, and win NFT prizes. Admins can add NFTs to different tiers, view the added NFTs, select winners, and remove winners from the participant list. The dashboard interacts with the Ethereum blockchain to perform these operations.

What I Learned
This project deepened my understanding of smart contract development, especially in the realm of NFTs. I honed my skills in creating secure, efficient, and user-friendly decentralized applications. Additionally, I took a deep dive into the react-spring library, discovering its powerful capabilities for creating fluid animations and transitions. I found it to be an invaluable tool and have plans to incorporate it into my future projects. The challenges faced during development provided invaluable insights into best practices and optimization techniques.
Challenges Overcomed
During the development of the slot spinner project, I implemented robust security measures to prevent potential reentrancy attacks. I also ensured gas-efficient contract interactions to optimize user transaction costs. One of the key challenges was addressing potential edge cases in the winner selection and prize distribution process. Additionally, I took on the task of creating a realistic slot machine animation, which provided a seamless user experience. Another intricate challenge was dealing with the display of different NFT image sizes as prizes. I ensured they were displayed properly without any distortion, maintaining the visual appeal and integrity of each unique NFT.
