ECDSA Node

This project is an excercise of the Ethereum Bootcamp for the Alchemy university website.

Further explanation about this project can be found here: https://github.com/alchemyplatform/ecdsa-node

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!

Key-pair generation

In order to get a fresh key-pair (private and public) you can execute the generate script in the server application.

1. Open a terminal within the /server folder
2. Run npm install to install all the depedencies (In case you haven't done it yet.)
3. Run npm run generate to generate and print in console a key-pair and the corresponding ethereum address.

Disclaimer

This project requests the user to input their private key for the sake of simplicity. Normally, we would use a wallet to sign a transaction before pushing it to the backend.

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