Fintech Finder is an application that its customers can use to find fintech professionals from among a list of candidates, hire them, and pay them.
I was tasked with integrating the Ethereum blockchain network into the application in order to enable customers to instantly pay the fintech professionals whom they hire with cryptocurrency.
I completed the code that enables customers to send cryptocurrency payments to fintech professionals.
To develop the code and test it out, I assumed the perspective of a Fintech Finder customer who is using the application to find a fintech professional and pay them for their work.
The fintech_finder.py file contains the code associated with the web interface of the application.
The code included in this file is compatible with the Streamlit library.
The crypto_wallet.py file contains Ethereum transaction functions.
By using import statements, I integrated the crypto_wallet.py Python script into the Fintech Finder interface program that is found in the fintech_finder.py file.
Integrating these two files automates the tasks associated with generating a digital wallet, accessing Ethereum account balances, and signing and sending transactions via a personal Ethereum blockchain called Ganache.
The steps for testing out the application are as follows:
- Import Ethereum Transaction Functions into the Fintech Finder Application
- Sign and Execute a Payment Transaction
- Inspect the Transaction on Ganache
Below is the resulting webpage from running the Streamlit app:
To test the app, I chose a candidate I would like to hire. Then, I entered the number of hours that I would like to hire them for:
I then navigated to the Transactions section of Ganache. See below a screenshot of my address balance and history on Ganache:
Below is a screenshot of the transaction details on Ganache:
I then returned to the original transaction, and clicked the transaction’s To address. Below is a screenshot of the recipient’s address balance and history from my Ganache application:
