BadgerBadges

Inspiration

UW–Madison students create memories every day: the first snow, an all-nighter at Morgridge, building at hackathons, or hitting academic goals. But there’s no trusted, unified way to record or prove these moments.

What it does

a blockchain-based achievement system that turns real UW–Madison experiences into verifiable, tamper-proof digital badges.

How we built it

Started with Hardhat to build the basic functions and test with local blockchain. Then, we rewrite the whole project using Solana. Lastly, we optimized the UI and fixed some issues to improve user experience.

Challenges we ran into

First time building a blockchain project, trying hard to understand blockchain basic concepts

Accomplishments that we're proud of

successfully built a smart contract for minting custom NFT

What we learned

• Concepts of smart contracts, private key & public key cryptography
• NFTs and how they are minted
