How it's made
Challenges we ran into Writing the marketplace contract was the biggest challenge I faced. But fortunately, Devfolio had organized mentorship sessions which help me a lot in solving problems. Another challenge was displaying data fetched from blockchain to the frontend as I was new to frontend development. But once I got familiar with the web3.js library it was very easy.
