Arbitrage Bot for NFT Tokens

During the winter 2022, I discovered a potential arbitrage opportunity by buying and selling NFT tokens using different currencies.

Initially, I created a small UI where people could operate manually, listing the tokens with the current spread and allowing the user to buy and list in bulk. After validating the potential, I created a bot that would manually buy, list, and re-list if it was not the best current offer.
