The problem D-Leaf solves

There has always been a lack of security in second hand ticket sales, as the buyer has to trust the words of the owner
that the tickets they are selling are legitimate and they will not sell the same ticket to multiple people. There have
been many cases when people found out that they were sold duplicate tickets or the same ticket was sold to someone else
also. So we try to solve this problem by converting the tickets into nfts and storing them on ipfs. This way the buyer
knows that the ticket cannot be sold to multiple people and the tickets are also legit.

Challenges we ran into

It was a very challenging project for us, we faced difficulties in routing of components, integrating metamask, connecting with IPFS server.
