Week 1 Project - Ethereum Developer BootCamp

Description

In this Project users can:

1. Generate a Private-Public Key Pair
2. Enter a Public key (sender), Amount, Recipient(recievers Address)
3. Click on transfer to Send the amount to the Recipient Address

• Under the hood the Public key cryptography is Incorporated
• Private Key is Never used on server-side , It is only used on client-side for Signing the Transaction.
• Many Ideas were Generated with the help of Alchemy University Community (Everyone who gave Suggestions are Considered Contributors of this Project )

ECDSA Node

This project is an example of using a client and server to facilitate transfers between different addresses. Since there is just a single server on the back-end handling transfers, this is clearly very centralized. We won't worry about distributed consensus for this project.

However, something that we would like to incoporate is Public Key Cryptography. By using Elliptic Curve Digital Signatures we can make it so the server only allows transfers that have been signed for by the person who owns the associated address.

Client

The client folder contains a react app using vite. To get started, follow these steps:

1. Open up a terminal in the /client folder
2. Run npm install to install all the depedencies
3. Run npm run dev to start the application
4. Now you should be able to visit the app at http://127.0.0.1:5173/

Server

The server folder contains a node.js server using express. To run the server, follow these steps:

1. Open a terminal within the /server folder
2. Run npm install to install all the depedencies
3. Run node index to start the server

The application should connect to the default server port (3042) automatically!

Hint - Use nodemon instead of node to automatically restart the server on any changes.
