Usage / Features

1. You can sign up or log in.

2. Go to the "Friends" tab to add a friend whom you want to request money from.

3. Go to the "Requests" tab to request a payment amount from your friend.

4. Your friend will see your requests in the "Dashboard" tab.

5. Your friend can choose to accept or reject your request. This process will take some time (> 12s). Solidity uses a proof of work mechanism which takes up significant time to confirm each transaction on the blockchain.
