I’ve got cryptokitties, EtherCraft Items, Gods Unchained Cards, Fighting Robots, Collectible Dogs, Artwork, and digital avatars all on my Ethereum wallet…..but man are they tough to figure out how to transfer, sell, or move.

This is what Mintable does, as easily as possible.

If you don’t know what ERC-721s are, here is a brief explainer…otherwise if you know about them, feel free to skip it.

What are ERC-721s

ERC-721 are tokens on the Ethereum blockchain that have data for each token, making them non-fungible (unique and without set value). These are trading cards, where each card is a token, and your collection of tokens make up a deck of cards for a game called Gods Unchained. Each player has many cards (owns many tokens).

You can get these items, called ERC-721 Non-fungible Tokens, by interacting with different services/games on the blockchain. Every week multiple new games are released where items or objects are made as ERC-721 tokens for you to digitally own via your Ethereum address. Items like collectible cats, pokemon cards, baseball cards, trading card games, resource management games, etc.

An Example of NFTs

To help wrap your mind about ERC-721s and NFTs (non-fungible tokens), I like to give this example.

We know tokens are these digital tokens you own, and we can see that you own these tokens by looking at your address, like you can see you own money in the bank. Since its the blockchain, you can see your balance of tokens, anywhere in the world.

A normal token, is just a token, think a digital coin. A coin doesn’t have a unique name for each coin, a coin doesn’t have an ID, its just a penny, and every penny is a penny.

A NFT (non-fungible TOKEN), is also a coin, but this coin has a USB chip in it, that holds data. So now when I give you a penny, it has a USB chip in it, that says my name, my phone number, and a message saying “Thanks for your lemonade, here is payment”.

This is the special metadata that can be put on a NFT. This metadata can be ANYTHING.

Lets imagine you are traveling the world and have an ethereum wallet, like your credit card or bank account, you will have it with you and have access. Since you know you have global access to the blockchain and NFT technology, you can take things a step further.

You upload your passport photo as an image to a NFT.

Don’t actually upload your passport, this is a horrible idea for security reasons.

You upload a picture of your passport, to a new NFT. This NFT is given to your ethereum address and you now own a token that has the special data you put on it. In this case its your passport.

You did this so that:

Now you can access a picture of your passport, anywhere in the world, as long as you have blockchain access.

You can verify that you are who you say you are, by using a KYC method built into blockchain services

If you lose you passport, you have a copy that anyone can get access to

(Note: Don’t actually do this. This is a horrible idea for security reasons — but this is a great example of showing ANYTHING can be used in someway with NFTS)

That’s one example of an NFT. It could be anything. It could be…

a newspaper clipping

a patent you want to have public proof of display

a deed to an item

a certificate

a digital item (video game item)

A token for access (social clubs, or physical access)

so much more…

Mintable— How you can create, manage, and explore all the Non-Fungible Tokens on the blockchain

Mintable is a dApp I’ve been building for the last 4 months. Its’ a resource for anyone who owns ERC-721s to use freely. You can manage 75%* of all ERC-721s out there. You can browse all the ERC-721s created on the blockchain. And its a free¹ generator that allows for you to create ANY ERC-721 you want, and have complete ownership and access to it, immediately.

(*This is the alpha, once the full launch happens, we hope to support 98%+ of all ERC-721s, ¹ Free during the alpha).

What You Can do on Mintable

You can:

Manage any ERC-721 token

You have entered the Address for the contract and it loads it from the blockchain

Also browse within that contract for all its tokens

This is the card you own, and you want to transfer it to a friend or sell it

Mint new tokens for contracts you own or made on mintable

Interact with the smart contract to transfer

Checking out all the other cards on the Gods Unchained Contract and maybe looking for a card you want
