Dpay

Inspiration:

A decentralized Paytm-like app has several advantages over a traditional centralized app: 1)Increased security 2)Increased privacy 3)Censorship resistance 4)Improved accessibility 5)Reduced fees

What it does:

It is a decentralized Paytm-like app

How we built it:

We will implement currency exchange in a decentralized manner

Implement QR facility to Solve the problem of money transfer from one wallet to another

Do currency exchange without involvement of any intermediate token

Whenever a user opens an account their wallet address gets hashed into a QR code (For hashing we can use QR JS)

To receive a transaction the user can share their QR code to anyone

Using JS QR library we will decode the QR to find out the user's wallet

The address will be passed in the smart contract to complete the transaction

Transactions will be stored in a decentralized database

We will use oracle chain link and price feed for ether to usdt conversion

Challenges we ran into:

Accomplishments that we're proud of
