On-Chain NFT Creator User Guide

Everything you need to know to create, manage, and trade your fully on-chain NFTs

Introduction

Welcome to the On-Chain NFT Creator! This powerful tool allows you to mint NFTs where all metadata and images are stored directly on the blockchain, ensuring permanent availability without relying on external storage solutions like IPFS.

What does "on-chain" mean? Unlike traditional NFTs that often store images and metadata on IPFS or centralized servers, on-chain NFTs store everything directly in the Ethereum blockchain, making them truly permanent and decentralized.

Getting Started
