About The Project

I initially built DEXcalculator as part of a programming challenge to find arbitrage opportunities between decentralized exchanges. Its main purpose is to calculate the prices of trading particular amounts of cryptocurrencies on particular exchanges. The particulars are chosen by user input, allowing one to find better prices for certain amounts of cryptocurrencies on different exchanges at different times.

Built With

• Python 3.6
• web3

Getting Started

Getting DEXcalculator up and running is easy (and free!).

Prerequisites

Before using DEXcalculator, one must create a free account on Alchemy.com to obtain an API key. The Web3 library is also required for DEXcalculator to make necessary API calls.

Installation

1. To use DEXcalculator, one must obtain their own Alchemy API key. This is quick, simple, and free to do. 1a. First, create a free account on Alchemy.com. 1b. Next, create a blank app using the "+CREATE APP" button (the app's particular parameters are not relevant to DEXcalculator). 1c. That's it! The new API key will be displayed on the Alchemy dashboard.

2. Install the web3 library, which is listed in requirements.txt. The easiest way to do this to download requirements.txt and use pip:

   pip install -r requirements.txt
   

3. Download DEXcalculator.py

4. Congratulations! DEXcalculator can now be used to calculate prices on decentralized exchanges. Simply run the .py file, input an Alchemy API key (or link), and choose the spending parameters to have the current price calculated! DEXcalculator can also be incorporated into other programs as a means of obtaining in-the-moment prices of specific amounts of cryptocurrency traded on specific exchanges.

Usage

Running DEXcalculator.py allows one to choose a cryptocurrency to spend, a cryptocurrency to receive, an amount to spend, and a decentralized exchange to do it all on. Doing so will display the price of per spent cryptocurrency of the cryptocurrency they will receive.

Importing DEXcalculator enables a program to quickly access prices of different cryptocurrencies on different decentralized exchanges. For example, the ArbitrageAggregator program uses it to find profitable arbitrage opportunities, in which a cryptocurrency is bought on one exchange and then sold on another at a higher price.
