Introduction

A mentor gave me an assignment at web3brigde to explain and build an ERC-721 token. In this article, I will talk about how the contract works, and what the functions in the contract do.

What is an ERC-721 Token

ERC-721 is a standard for creating unique, non-fungible tokens (NFTs) on the Ethereum blockchain.

This is like a fancy way of saying each token is unique and not interchangeable with any other token. For example, each NFT can represent a specific item, like a piece of digital art

ERC-721 as a set of rules and guidelines that developers follow when creating NFTs. These rules ensure that all NFTs created using ERC-721 can be easily understood and interacted with by other applications, wallets, and marketplaces.
