FirstCrypto - A Finance App for Millennials

Problem with crypto

Everyone wants to own crypto or wants to invest into it. People who are living into currency devaluating countries, they are looking crypto as a future of their daily finance and to beat inflation.

But onboarding to crypto is very complex.

• If you go to Decentralized exchanges, you need to first create a wallet, you need to keep seed phrase at some safe place, you need to understand hard core terms of crypto
• If you go to Centralized exchanges, KYC process takes 1-2 weeks, also a centralization risk, chances scams and much more.

Solution we wanted to build

A complete finance application built on Blockchain with easy and smooth onboarding, free from gas managements, payment solutions and various investment options for millenials to own crypto at better prices.

How it works

We have created a web application, but soon we will create a mobile application. In this dApp, users can easily onboard with their regular web2 method such as Google, facebook, Mobile no and they can easily buy usdt using on-ramp solutions. They can buy their favourite at a regular interval with Dollar Cost Averaging strategy without transaction fees management. And more interestingly they can pay crypto tokens through regular UPIor just by scanning the QR code of linked UPI of user.

Making a smooth onboarding

The biggest chanllenge we face in building a smooth authentication process, After lots of research we implemented the Safe Auth Kit to implement social authentication. Making transactions gasless was also another challenge, so Safe aslo provides gasless transactions relay using Gelato, we implemented that.

Swapping Tokens seamlessly

Initially we were building the swap functionality using UniswapV3 router that made our implementation unviable and hard to implement.Thanks to 1Inch fusion swap, We implemented the Swap usng Fusion SDK and also implemented the user portfolio and dashboard using 1Inch APIs

Pay Crypto via UPI

UPI payments is one of the most successful technical solution ever in financial ecosystem so we thought to leverage that method. We implemented the Pay via UPI method using Waku Communication protocol which is very secure and scalable.
