Create contract

This guide explains how you can create a smart contract for your NFT collection on the blockchain.

What is an NFT Contract?

An NFT contract is essentially a smart contract designed to handle NFTs on a blockchain. It governs how the NFTs are created, transferred, and interacted with. This contract holds all the necessary logic and data structures for minting new NFTs and managing their ownership.

The creation of an NFT contract is the deployment of a new smart contract on a specific blockchain. The concept of a contract can be considered as the creation of an NFT collection.

Let's start by defining your first contract. This contract will represent a collection for the NFTs. We will create a contract on the Polygon (MATIC) testnet chain.
