The problem EtherX solves

This minimal wallet helps the user to store Ethereum-based coins and transfer them between different addresses.

We have used Firebase(firebase_auth package) for authenticating the user and logging him in/out.

Front-end :

• Flutter and Dart for the complete project.
• velocity_x Dart package for designing the homepage of the app.

Back-end :

• MetaMask wallet as the sample/test wallet.
• Truffle for creating and deploying the Smart Contracts written in Solidity.
• Gnache for running a local Blockchain.
• Infura for deploying the Smart Contract on a test network.

We've used the following Flutter packages :

• firebase_auth
• firebase_core
• web3dart
• velocity_x
• http

The apk file for this app can be downloaded at the second link.

Challenges we ran into

• The backend part, specifically connecting our app to the deployed Smart Contract was tricky.
• We had a hard time getting around the web3dart package in Flutter and integrating our server-based blockchain with the app.
• We faced some errors while deploying the Smart Contract using Trufffle as well.
