How to Mint an NFT on the Kaleido Platform

NFTs, or non-fungible tokens, are a type of token native to the Ethereum ecosystem. Defined in ERC-721, NFTs are a provably unique digital asset where end users can easily distinguish each NFT from another. Whenever a NFT transaction occurs, it is recorded by the block chain. NFTs can represent anything from digital art to actual physical assets.

Why mint NFTs on Kaleido?

Kaleido makes it very simple to deploy your own NFT smart contract and start minting NFTs. There are many reasons to mint a NFT on Kaleido. For one, minting and transferring NFTs on Kaleido requires no  gas meaning there is 0 transaction cost to you! On platforms such as Opensea, Rarible, or others, NFTs are hosted on public chains. You will need to connect and fund a wallet with an appropriate cryptocurrency in order to do any sort of transaction because those chains require gas to pay for the transaction..

A second reason is platforms such as Opensea, Rarible, and others are inherently centralized. For example, Opensea takes a service fee of 2.5% in addition to gas fees for any sales of NFTs. On Kaleido you are able to mint NFTs on your own chain and dictate custom properties. For the purposes of transparency, Kaleido also offers tethering services to public Ethereum which allows you to share the state of your private ledger which gives you history re-write protection from thousands of public Ethereum nodes, while retaining the privacy of a private chain. For more information on tethering, refer to our article, Pin State Proofs From Your Private Chain to Public Ethereum Networks.

In this article we'll go through the four simple steps needed to mint a NFT on Kaleido—all of which can be done in 5 minutes or less.

4 Steps to mint a NFT on Kaleido

Step 1: Create a Kaleido account

If you haven’t already, sign up for a Kaleido account here. Create an account and password and you will be all set. NFTs can be created with any plan on Kaleido, starter tier (free) included!

Step 2: Create a blockchain network

To get started, create a blockchain network. You will need to name your network and select deployment region(s). This is where your resources will be hosted and there are various options for AWS and Microsoft Azure.

After your network is created you will need to create an environment. There are options for different protocols, however, to mint a NFT make sure you create an “Ethereum” one. You will also need to select a provider.

For our purposes any will do but if you are curious about the differences here is a technical overview.

You’re almost there. Once your environment is created, set up a node and leave the default configurations of “small” and “signer” on the final panel.

Step 3: Create a Token pool

Now that your blockchain network is created, navigate to the “digital assets” selection in the left panel and click “tokens”. Select the Signing Account as the node you created in the previous step which will be used to deploy the token contract to the blockchain and create using our Token Factory. To mint a NFT, make sure to select either KaleidoERC721Mintable or KaleidoERC721MintableBurnable.

Next, give your token a name and symbol and click “deploy token instance”.

Step 4: Mint your NFT

Now that you have deployed a ERC721 contract, the next step is to mint your NFT. Go back to the left navigation and click on “tokens”. You should now see your created NFT. In the top right, click “select signing account” and pick the same account you used to create your NFT.

Next click mint, give your token an unique numerical ID, and token URI if applicable.

The token URI is used to point to a unique image for the NFT which contains metadata (example below).

‍

{

   "name": "NFTexample",

   "description": "Example of a NFT",

   "image": "https://example.com/NFTexample.png",

   "attributes": [

       {

           "trait_type": "ease_of_use",

           "value": 100

       }

   ]

}

The URI is optional but recommended and more information can be found here. Congratulations, you have now minted your first NFT!

Repeat step 4 to mint as many NFTs as you would like.
