The problem D-Tree solves

We provide a one stop portfolio page just by connecting your wallet address. After connecting wallet, profile page will be displayed and the first part contains the Social Handles of the address owner. The next section contains the link to the block explorer of the address. In addition, we have added few portfolio analyzers such as portfolio.nansen, debank.com and zapper.fi. We have also added a search option to check others portfolios using their wallet address or ENS username. We can also send a raw transaction in thier portfolio page with a message and also send crypto.

We have used ENS API so that we could enable portfolio search with thier ENS username.
For storing data in decentralized manner we have used IPFS for data storage.
We use push protocol in our DApp to Send and Get notifications.
We used polygon matic network to run our Dapp.
We used lens protocol to get users data

Challenges we ran into

The main problem that we faced is when we store data on IPFS we obtain a hash for it. So, when there is a updation in the data by the user the hash of the IPFS changes. So we faced trouble in updating the hash value in the script every time there is a change in data and hash in the IPFS
