Punchable

What it does

It allows users to create, sell, and buy boxing-related NFTs. Also, new users have the option to mint a (random) NFT.

How Chainlink is used

Chainlink's VRF is used in the getRandomNFT function to randomly pick a URI from an admin-created list, which is then used to mint a new token and assign it to the user who called the function.

Other Technologies used

• Polygon / Matic
• Alchemy to connect to the Polygon Mumbai testnet
• NFT.Storage to save off-chain NFT metadata to IPFS
• Moralis to manage users and react-moralis for user-management hooks and context
• OpenZeppelin's Contract library
• Metamask to handle Smart Contract transactions
• Solidity, Truffle and Ganache

Challenges I ran into

I think the hardest part was coding the FE (spent like 2/3 of my time doing it) since I kept making tweaks to the UI; but, overall, I'd like to thank the sponsors for making it easy to implement their products/tools.

Accomplishments that I'm proud of

Delivering an MVP on time.

What I learned

How easy it is to go from an idea to an app in the new decentralized Web thanks to all the tools I was introduced to in this hackathon.
