City Planner was the second iteration of my City Parks project! I wanted to provide extra fun to the holders of City Parks by using the same constructs to create new, unminted parks.

I first built a drag and drop tool for a user to create their own City Parks. Then I did an auction of a completely blank City Parks, with the winner having the ability to save their custom City Parks on-chain!

The contract for doing this was here. The auction settled at 0.769 ETH.
