Parking in the concrete jungle made easy.

PeerPark is a contactless parking space lending network, that allows users to find parking more reliably and affordably, as well as earn off of their unused driveways and spaces. Users can schedule periodic times they are away from home, like work and school, that become automatically listed. Using the public ledger, unreliability and overparking are deterred through progressive consequences enforced by smart contracts. PeerPark is the solution built for navigating through the chaos of urban cities effectively.

How we built it

The frontend of our web application was built with css, html, vanilla js, and velo. We used Scaffold-ETH to build Solidity smart contracts, which deployed on a test net for this hackathon with Hardhat. React and Moralis were used to implement our web3 integration on our website. The hardware prototype was built using Arduino, and C++.

Challenges we ran into

A challenge we faced was integrating our web3 sign-in and smart contracts with our website.

Accomplishments that we're proud of

We managed to finally figure out an idea quite late; after the first day of workshops. We also created a physical component with the Arduino that we never intended on actually producing as a demo.

What we learned

We learned a lot about web3 smart contracts, and integrating all of that with physical hardware and C++.

Check out our vlog from the weekend!

What's next for PeerPark

Implementing an ios and android version of the application, as well as deploying the smart contracts to the Ethereum mainnet, and possibly testing with a userbase.
