How to mint ERC-721s and sell those digital items using Mintable

A guide to selling NFTs (ERC-721s) using Mintable

This is a guide for understanding how to create Non Fungible Tokens (NFTs) to represent digital items and how to sell these tokens for Ether.  This guide is a bit of a beast but we wanted to make the minting process super simple and have you making your very own smart contracts in no time.

But before we do - If you are not familiar with the terms Non Fungible Token (NFT) or Smart contract, or want more clarity on what they are, have a read of this. If you are new to Blockchain this is pretty important.

If your into solidity coding or you already know what you are doing, just go straight to Mintable.app/create and get going.

If you are a true crypto head- you have probably heard about the smart contract standard ERC-721  and its term as a Non Fungible Token (NFT). Most often NFTs (digital items) are discussed as game changing technology and will revolutionize the world we live in  - allowing peer to peer trading and establishing trust in ownership among digital items.

These NFTs have been around since 2017 gaining notoriety for their use in crypto collectable games like Crypto kitties, Axies, Gods Unchained and a whole raft of others. They work very well for collectable games and give us a glimpse of their potential. But there are other use cases that most people don’t even begin to consider...

Outside of digital cats and card games how can they be used? What else can be tokenized as a digital item? How do you make your digital item? How can you actually use them to exchange your own digital items?

Mintable has the answer and this guide is here to help you do just that. Read on and we will show you how to create your own NFT for anything you like and how you can sell that NFT for Ether - all using the blockchain without needing any documentation or knowledge.

What can you create using Mintable?

Mintable allows you to create your very own ERC-721 standard smart contract and mint non fungible tokens for that contract. - nerd talk

Mintable lets you create a digital item that you can sell for cryptocurrencies on NFT marketplaces. So you can take a picture, some characteristics, give it a name, make it rare, and sell away for a profit. With each smart contract you can create multiple tokens and these tokens can be used to represent your digital items.

Here is an example: You are a graphic designer and you can make really cute or scary monsters. You make 50 of these unique cute things, and create a smart contract using Mintable called “My Scary Monsters - Limited Edition 2019”.

Then each token, is actually a picture of each one of your monsters. You can sell each token for whatever price you’d like, and if someone wants it - they can buy it!

If you promise to only make X amount - or have a social media following - users will find value in your creations. These types of tokens are best for people who have social media followings like Youtube creators, Twitch Streamers, or Twitter personalities.

Mintable also lets you manage all of your current digital items you have - such as any Gods Unchained Cards, Axies, Blockchain Cuties, CryptoRome Items, Crypto Assault units…. And the list goes on. It’s the easiest way to transfer, browse, and interact with your digital items - guaranteed. 3 clicks to transfer an item and it doesn’t matter if your wallet even knows about your token (some wallets don’t display your items, but as long as you own it, it will work)!

 

How is Mintable Unique

Dapps like crypto kitties and Marble cards have their own smart contracts and tokens however what the tokens represent is already predetermined. In these DApps the tokens you own are restricted in what they represent; Cryptokitties tokens represent a line of code and Marble Cards represent a web link.

Mintable is unique because it allows you to create and own the smart contract. You decide what the contract is for and you choose what the tokens represent and how many there are.

So how can you use these tokens in the real world?

There are a number of ways you can use your tokens, some of these include:

  • Establishing ownership of an item external to the token
  • Establishing who is allowed access to content or locations
  • Linking the token owner to a web URL, a photo, video or other web based asset
  • Establishing ownership of something in the tokens Metadata
  • Creating tokenized assets that you are a middle man for
  • Creating content to sell
  • Tokenizing content
  • Tokenizing anything that could have value
  • Creating value with a token and data - if you have an online store you can accept that token as a discount card
  • Utilizing tokens for your business in the form of credit, discounts, or coupons
  • Event ticketing as a token
  • The list goes on….

There are probably many more ways to use them but this is where you need to get creative

Example 2: You might be a photographer who wants to create a smart contract to sell your photography on the blockchain. You can create the smart contract on Mintable and then mint tokens to represent the photos you are selling. Each token could relate to a different photo and give the owner of that token ownership of a specific photo that token relates to. You can then sell these tokens with the smart contract ensuring the transaction works and is successful.

Don’t worry if you aren’t a photographer, there are many other things you can create and sell with Mintable:

  • Create your own crypto collectable cards (like crypto kitties or Marble cards)
  • Sell tickets to an event where whoever owns the token gets access
  • Sell your digital photography or digital artwork
  • Design new content such as characters or badges
  • Raise funds for a project by selling tokens which give rights to something (just like Kickstarter does)
  • Sell access to videos or audio content you have created
  • Create a link between your real world business and the token (could be a discount card, a form of credit)
  • Create public verification of some data: such as: “I published here publically this patent idea on the day of XYZ” for public proof (its always on the blockchain!)
  • Sell rights to the tokenized asset if you can mediate the content transfer

How can you represent your asset as an NFT?

Ok, so now we have some ideas on what to create lets look at the how you can create your smart contracts with Mintable’s ‘Create’ function

Mintable offers an easy to use Smart Contract generator that takes you through the process of creating ERC-721 standard contracts and NFTs step by step.

Don’t worry if you don’t know how to code, we’ve got your back. With Mintable you can create a smart contract without any knowledge of how to code. We do all of that for you, all you have to do is put in the right information when prompted.

When creating a Smart Contract you are creating 2 things:

  1. The smart contract to hold your tokens. This is the ‘store’ for your items. If you wanted to make a Pokemon Card Game clone - the name of the smart contract would be Pokemon cards. Where each token in the contract would have its own name, like pikachu, charizard, etc.
  2. The first token made in the contract is made when you create the contract. You can think of this as your “genesis” token. It can contain extra data about the contract, or it can just be another normal token. It will have an id of 0 (zero).

See our guide on 20 different items you can make here: 20 Items you can make as an NFT on the Ethereum Blockchain

 

How to sell NFTs for crypto using Mintable

Mintable is unique because it allows you to create and own the smart contract. You decide what the contract is for and you choose what the tokens represent and how many there are. Below are 20 examples of what you can do.

Note: If you are an existing retail business you can sell your items via NFTs — verify ownership of the token via customer support and then you can send them the physical item. Information on how to perform all this should be included in the NFT you make for consumers to buy.
