Axie Infinity - Breaking the market with bots

As many of us know, Axie Infinity has quickly risen to become the #1 NFT powered game in the world, with that, and ever growing market reaching $670M worth of transactions in the past month, it is also a great playground for developers to learn and practice new skills.

In this article, will go over one of my github repos, and learn how to setup a bot to scrape data from axie.zone (community website providing leaderboard information) and in combination with axie infinity's graphql API, find the Axies played by the top 100 players on the marketplace.

While we likely are not able to find the exact Axies (same ID), we can find Axies with the same class, as well as parts, that make them practically identical in combat, allowing us to recreate the best teams on budget.

Instructions

Clone the Github repo

Create a Firebase account & Project

Enable Firestore

(optional) Enable Authentication using Google.

(optional) Update security rules to enable any authenticated user to read data (this setup is assuming usage with the provided Web GUI, if used within your own project tailor your security rules to the given project).

Example:

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read: if (request.auth.uid != null);
    }
  }
}

Within Firebase, navigate to Project Settings > Service Accounts, select Python and click on "Generate new private key"

Rename the file to serviceAccountKey.json and import it into the project directory ./database/serviceAccountKey.json (this file is included in .gitignore)

Create virtual environment

Use the package manager pip to install dependencies from requirements.txt file.

pip3 install -r requirements.txt

Run main.py, after script finishes, your data will be loaded into two collections, leaderboards (top 100 players at the runtime, multiple documents) and on_sale (all axies matching one of the most used axies by top 100 players, including their price, which top 100 player it matches, ID, class & parts, see example json below).
