OpenMinter – An NFT Minter That Provides A Gateway For NFT Creation & Interaction

In this article we explore OpenMinter and how it can interact with other NFT/DeFi components such as the Kukai Wallet and the Kalamint NFT marketplace.

What Is An NFT?

An NFT is a Non Fungible Token. This means that these tokens are exclusive and unique. Unlike fungible tokens, like BTC, ETH or XTZ. Fungible tokens are like coins.

If you have a stack of dimes, they’re all the same, it doesn’t matter which one you take out of the stack. They all look the same and they all have the same value.

An NFT on the other hand, is unique. Compare it with a stack of playing cards. All of them are cards, but still they’re all different. It matters whether you pick an ace of hearts or a jack of diamonds.

They are both unique playing cards with unique features.

NFT’s are big on Ethereum and used for a whole lot of different use cases. They are used to tokenize art for example. Or objects in games, digital card games for example.

Ethereum transaction costs are beginning to become an issue though.

Here’s where Tezos comes in to play. Tezos’ transaction fees are on average 3,000 times cheaper than Ethereum. So this use case on Tezos is a great step forward for anyone who wants to mint and trade quality NFT’s in an affordable way.

We have heard about Kalamint, which is an NFT minting and trading platform on Tezos that is about to launch the 18th of this month. Additionally, TQ Tezos just announced OpenMinter.


OpenMinter is not a platform that also enables trading, but it is a tool for creators who want to do their own minting, or launch their own marketplace. So it enables you to mint an NFT straight to your wallet, or it could function as a component that developers can implement in a marketplace, or trading platform they are building.

OpenMinter is a free tool that offers sovereignty for creators without intermediaries. All you pay are transaction costs, which are obviously minimal on Tezos.

And due to the use of the Tezos NFT token standard, the produced NFT’s are compatible with other Tezos-based components. This means that NFT’s that are minted can be sent to Tezos wallets, or to platforms like Kalamint.

Paying for mining costs can initially be done in XTZ, but OpenMinter supports FA2 compliant tokens like USDS and later others as well.

USDS is a stablecoin that is being deployed on Tezos and makes use of a function that’s called “TZIP-17 permits”. This is basically a small scale Layer 2 (L2) solution that enables users to send a transaction through a second layer, off-chain, which the user can pay in a different currency before the second layer sends the transaction to the blockchain.

The second layer will pay the XTZ needed for the transaction. This could be very convenient for users that are just being introduced to the Tezos ecosystem.

People have already been experimenting with OpenMinter including NFT artist Chris Carella who minted what is thought to be the first NFT using OpenMinter here. This can be seen on the Tezos blockchain here.

If you are interested in testing out OpenMinter there is an initial guide and tutorial here. It is expected more in-depth and user-friendly guides will be published in the coming weeks.


Another convenient component in the Tezos ecosystem is the Kukai wallet. OpenMinter will integrate with a number of wallets, Kukai being one of them.

Kukai wallet enables you to send XTZ to and from Twitter, Reddit, and Google accounts. This means that if you are logged in on, for example, on Twitter, your browser connects Kukai with your Twitter account after you open Kukai. And that’s it.

Now you can send and receive XTZ from Kukai. No private key, or public key to store. That whole process is moved to the back of the user interface.

On top of that, you can send XTZ to Twitter, Reddit, or Google accounts that have never opened a Kukai wallet before. You could send XTZ to a friend who never even heard of Tezos before. They’d get a DM (Direct Message), or an email that notifies them they received XTZ and explains how they can open Kukai.

OpenMinter and Kukai bring a new dimension to this. Kukai just added token support, which includes NFT’s. Now you can send digital collectibles of any kind and any value the same way.


Maikeul is an NFT artist that is about to take the leap from Ethereum to Tezos. He was mostly working with KnownOrigin and Rarible. You can check out some of his work here. He plans to use both OpenMinter and Kalamint.


Maukeul’s first collection to be published on Tezos is called ‘Faces’ and will be minted and offered on Kalamint.

You can see an example of the collection that will be available as a first drop exclusive to Kalamint here:

My journey into the unknown… By Bruno Magnifico

I am glad I eventually read one of the Manchester United emails last December 2022. I have learnt so much about the power of Tezos, how artists, companies and brands use the power of the technology. More and more big brands, small brands, football clubs will all soon join the ‘revolution’ of the digital collectible and offer utilities to people.
