The safe way to giveaway

“Privacy is not something that I'm merely entitled to, it's an absolute prerequisite.” — Marlon Brando

Giveaways are ubiquitous in the blockchain space, especially on platforms like X. Typically, users must post their wallet addresses in the comment section to participate and claim their prizes. However, this practice poses significant privacy risks and offers no guarantee of entry into the raffle or giveaway.

Trophy is an innovative use case of Solana Blink, utilizing embedded data to streamline interactions with links posted on X. This approach makes giveaways and raffles systematic and secure, requiring just 0.0001 SOL for participation. Here’s how it works:

1. Sign-Up: The user enters the giveaway by completing a transaction of 0.0001 SOL.
2. Data Capture: The link captures the user's public key/wallet.
3. Entry Queue: The user's wallet is added to the participant array.
4. Capacity Check: The system monitors if the maximum number of entries has been reached.
5. Winner Selection: Once the participant limit is met, a random index is generated to select the giveaway winner.

This process ensures a seamless and secure one-click participation in giveaways.

Utilizing Solana action, we create a use case of Blink and develop the project using TypeScript, Next.js, Node.js, and Vercel for deployment. We also use Solana Explorer to test our project and check how many participants are currently in the giveaway.

We have a diverse skillset, with strengths in UI/UX and other programming areas. However, our experience with TypeScript, the primary language for this project, is limited, especially for some newer programmers. This necessitates additional support to ensure everyone can effectively contribute. Additionally, balancing this project with existing commitments like academic workloads and other events presents a time constraint. Despite these hurdles, the team remains dedicated and committed to attending the build station and actively participating in the hackathon.

The hackathon was a great learning experience for our team. We explored new programming languages for us, TypeScript and Tailwind CSS, and used them to build a Blink. We familiarized ourselves with Git, as well as how to make get and post requests. This hands-on project helped us solidify our understanding of these languages. We also honed our teamwork skills by sharing ideas, splitting tasks, and collaborating effectively. The hackathon provided a platform for connecting with others. We talked to fellow participants and learned from their experiences. The time constraints pushed us to be more selective with our ideas, prioritizing features achievable within the timeframe.
