What is a NFT?

In short, an NFT is a digital asset that represents real-world objects like art, music, in-game items and videos. You can think of it as a digital representation of the creator's signature authenticating that a digital artwork is the original version and not a copy.

An NFT is ideal for preserving the rarity and establishing the ownership of digital and real-world assets. This is why many artists, celebrities, and collectors are increasingly adopting NFTs.

NFTs in the World of Art

In the context of art, creating a NFT (also called 'crypto art') of a digital artwork assures that is provably unique, scarce and only one person can hold ownership. You can just sell that particular artwork like you would have done offline.

NFT Artworks have gained massive popularity in the media. The most famous example is "Everydays: The first 5000 days" by artist Beeply. It was sold for almost $70 million through an online auction by Christie's.

NFT Minting Service

Are you ready to put your artwork on the blockchain? Colonia-Art has created its own NFTs (say 'Nifties') and created them for artists as well.

There are two ways to do this. The first option is that Colonia-Art creates the NFT for you, and then hand it over. We charge a fixed amount for this. Then we will proceed to send it to a wallet-address, that you manage yourself. You can decide to put it up for sale on one of the various NFT-marketplaces, gift the NFT or keep it for yourself.

This is what you need to do:

  1. Tell us more about the digital artwork: title, characteristics, and files.
  2. Request a Quotation.
  3. We mint the artwork and transfer it to your wallet. It is 100% yours.

The second option is that Colonia-Art takes care of everything: creation, presentation ánd selling the NFT. A big advantage of this is that you do not need to manage a wallet yourself nor have the blockchain's native currency to pay for fees when you mint or transfer the artwork.

Usually, we put the artwork up for auction/sale through our gallery on one of the largest NFT-Platforms: OpenSea. If you prefer an alternative NFT-marketplace, i.e. Nifty Gateway, Rarible, or Foundation instead, let us know. This is also possible.

Regarding the 2nd option, we work on a commission basis. Contact us and make sure to attach information about the artwork via the contact form or mail us directly at

Of course, all crypto artworks will also be presented via Colonia-Art. The purchasing process will be handled via the NFT-marketplaces.
