CeFi DeFi Arbitrage

A simple Cefi-Defi live arbitrage opportunity detection tool.

Project Architecture

There are 3 apps in this project:

• cefi app, where crypto prices are pulled using the Binance public api.
• defi app, where crypto prices are pulled from the 1inch data aggregator.
• arbitrage app, the prices between the cefi and defi are compared to identify arbitrage opportunities.

The cefi and defi apps are APIs with processes running in the background to pull prices.

The arbitrage app is a Flask web application which displays a dashboard with the prices, expected profit and is used to notify the user when there is an arbitrage opportunity.

Unit Testing

Unit tests were written using the pytest library. There is a tests folder in each app. To run the unit tests, navigate to the project directory in the command line and type "pytest" followed by the path to the test file. An example is shown below to run the unit test from the cefi app:
