The Most Popular Type of Digital Item — Blockchain Avatars — Create your own

The most common item on the Ethereum blockchain as an NFT is an avatar. These are just images or characters — that are actually tokens. Read more if your confused….

If you don’t know what ERC-721 digital items are (called NFTs) or non-fungible tokens on the blockchain — see more about these digital items here

These are all items you could consider to be avatars.

Each of these items are NFTs (non-fungible tokens) and they are mostly for games. Meaning your cryptokitty is a token and that token has meta-data on it — that controls how it looks or acts.

Think about it this way — token 1 = “Brown fur, Blue eyes, Spots”. token 2 = “White fur, no eyes, scary face”. This is basically what an NFT is — a holding-pen for a character’s data.

The most common type of NFT made on the blockchain — are avatars. Such as cryptokitties, crypto celebrities, cryptohorses, etc. Most of these (90%) are game items meaning the data is used within a game or system that says “ok you have a blue cat with furry hair!” then displays it and lets you interact with it in someway (either battling, trading, breeding, etc).

So we are going to show you how to make your own blockchain avatar in 5 minutes.

Non-fungible tokens are powerful — from selling artwork, to cryptokitties, to creating an avatar. Here is an example of how its done — its super simple here are the steps:

  1. Make your Smart Contract — 3 mins
  2. Mint however many tokens you want — 3 mins
  3. Sell and advertise these tokens — (???) mins
  4. User buys token and can show off their avatar in their wallet
  5. User can resell avatar if it has value

Community gives an item its value — if you want your avatar to have value — you need to create a community around it

Or use your social media following….. if you have a large following there is a good chance people will buy these avatars you make.

First off: “Why would I do this?”

  1. Your a graphic designer who wants to put out some art/content
  2. You want to earn crypto from selling stuff — its super easy to do it now, so why not? Instantly sell items for ETH/DAI on using Mintable
  3. You have a game or business and don’t know how to make smart contracts or don’t want to pay thousands to hire a smart contract developer

Before you Start

If you are new to blockchain you will need to do a couple of things. If you already have this nailed you can jump to the next step:

  1. Install Metamask — Link or use a mobile wallet like Ambo or Coinbase Wallet
  2. Set up your wallet and load it with ETH — You can buy ETH directly via metamask via https://coinbase.comguide to set up your wallet

Step 1: Create a Smart Contract on Ethereum (time: ~3 min)

Using the UI on Mintable you can create your contract without needing to know how to code. Here is how I would set up my Smart Contract if I was a graphic designer who wanted to make a blockchain avatar as an NFT.

My smart contract I’ll create.

Go through and add any information you think is related or relevant for your group or users to know. You have 20 fields of data that could include:

  • Your website
  • Details about the avatar/character
  • terms and services
  • Stats/data for the item
  • Cost of purchase, etc etc.

After you’ve confirmed its looking good — submit your transaction via metamask an Ethereum wallet in your browser.

If you don’t have Metamask or If your on mobile — use Coinbase Wallet or Trust wallet on iOS/Android

You just made a smart contract in this step — that contract has a unique address that no other contract will ever have — this is called the contract address — you can manage your token at anytime by going to:

Step 2: Mint your tokens (time: ~2mins)

After you have confirmed your ethereum transaction you will have an email copy — and also a screen that presents a receipt page

Load your token in the manager by either:

  • going directly to it via the url style above (
  • going to your profile and seeing your history then pressing view
  • Finding it via the contract address on the manager page

Once loaded you’ll be able to do this…

Going to mint 5 tokens at a time because I only picked 5 batch minting

Here is where you mint new avatars — or items. In order to create tokens on your smart contract — you need to mint them. So here we are going to mint 5 tokens of my character — because maybe I only want 5 — or because I didn’t buy the 40 batch minting package.

Making my avatars under my genesis shop contract (where all my items are stored)

These are also automatically added on — the leading exchange to buy and sell NFTs (digital items)

Step 3: Go to Opensea and sell away! (time: ~5mins)

Now that you are done minting tokens — you can go to and search for your contract’s name — or go directly to your contract using a link like this:

or press sell on OpenSea

Here you can set the price for the sale — and then share the link to buy it. Thats it. Your done.

Its that simple within ~5 minutes you’ve created a smart contract and tokens a digital items on the blockchain. How cool!

What Else Can I Create Using Mintable?

Mintable lets you create a digital item that you can sell for cryptocurrencies on NFT (digital items like ERC-721s) 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.
