Tracking NFT Transfers using Astra DB and Web3.js

This post introduces NFTs (Non-Fungible Tokens) and explains how to load them into DataStax Astra DB, a multi-cloud database-as-a-service built on Apache Cassandra. It covers the definition of NFTs, their types of smart contracts, and the process of using the Astra DB data loader to store every NFT ever minted in Astra DB. The post also discusses how NFTs are purchased and sold using cryptocurrencies like Bitcoin or Ether via auction house websites like OpenSea or Rarible. It further explains the concept of NFT smart contracts, their programming within blockchain, and the two main standards (ERC-721 and ERC-1155) that guide developers in interacting with NFTs. The post concludes by demonstrating how to pull NFT transfers, grab metadata, store it in Astra DB, and search for an NFT within the database.
