That’s a wrap! The Replit and OpenSea virtual hackathon “Hello NFT World” has ended! We’d also like to give a shoutout to our partners, DoraHacks, and Buildspace.

Hello World meets web3 🖥️

The Hello NFT World Hackathon encouraged the advancement of web3 by bringing together creators, artists, developers, and entrepreneurs as “BUIDLers” to create innovative web3 NFT Projects.

Together, they pushed the boundaries of NFTs and surfaced new types of utility. Over the course of eight days, projects explored various concepts ranging from web3 education, NFT DeFi, and even blockchain dating!

In summary, a total of 73 teams submitted BUIDLs to the four Hello NFT World tracks:

How winners were chosen

Each BUIDL track had a $5K first place prize, but it didn’t stop there. The top three BUIDLs in each track advanced to the $25K Quadratic Voting round. A total of 12 teams battled it out in the Quadratic Voting round.

What is Quadratic Voting, you ask?

A voting scheme introduced and often discussed in the Radical Markets community. It is often considered an innovative improvement of the traditional 1-person-1-vote or 1-dollar-1-vote voting schemes. The simplified formula on how quadratic voting functions is cost to the voter = (number of votes)².

The First Place Track Winners

Gaming and Metaverse

Belly NFT

A collectible, craftable NFT experience!

Belly.io rewards loyal fans with NFTs. As content creators, Belly wanted to BUIDL a way to reward their loyal fans. As developers, they wanted to do something fun and creative, and since so much of their content in the past revolved around food, a collectible, craftable NFT experience seemed like the perfect way to do all of that! Check out the demo, visit the Belly NFT BUIDL.

Most Hilarious

Spamazon

Buy anything with anything.

Have you ever wanted to trade your 10 ETH NFT for a $20 book? Well, Spamazon has the place for you! Spamazon gives NFTs a new purpose: payment for a purchase, on or off the blockchain. If your local food or furniture store has a risk appetite, they can accept NFTs as payment or collateral until payments are made using all Spamazon. Buyers can benefit from bartering with their NFTs or posting them as collateral until they daytrade for enough money to repay. A store that adopts this concept can reach a new market that doesn't require an intermediary trade for currency. Ready to LOL? To learn more, visit the Spamazon BUIDL.
