NFTs on Signum

Signum is a pioneer of truly sustainable, decentralized blockchain solutions, which also makes it perfect for green NFTs without wasting neither energy nor blockchain space. — NFT portal

On the 2nd of May 2022 the Signum-Network started its own NFT portal providing artists a green alternative to mint, buy, and sell NFTs.

Powered by the underlying sustainable blockchain technology from Signum, anyone can use the portal without hesitation to show the world their unique digital arts.

Decentralised and serverless

The portal is using a decentralized storage of the data for the NFT with IPFS and In addition, the setup of the portal is completely serverless and able to manage thousands of millions of requests.

The logic of the NFT to buy, sell, transfer, give it a Like and even more is managed by the smart contract logic build on the Signum chain.

And unlike other blockchains, Signum is not storing the same smart contract over and over again, instead the code is stored only once on the chain. When an artist deploys a contract the code is a transaction reference which costs no space on the chain and only the data stack which is used to handle the logic of the NFT is individually saved to the chain.

Using this smart approach makes the minting of NFTs on Signum incredibly affordable — with only 0,4 Signa (currently 0,0024 $).

We believe no other chain can beat this taking into account that Signum is truly sustainable and nearly C02 neutral, with a fixed minimum fee of 0.01 Signa.

Easy onboarding to the portal

The portal is built by the current Signum-Network development team, but the input and the feedback loops together with the Signum community in the last 3 months, while creating the MVP (Minimum viable Product), was amazing.

Finally, we even did much more than a MVP and the portal has a wonderful user experience to onboard new artists or collectors.

Roadmap for the portal

The current portal is just the start of a journey with our community to grow the functionality and eco-system around the NFTs.

Next Milestones:

  • A mass upload tool
  • A candy machine — fully onchain
  • Token economics for royalties
  • NFT Gaming support


NFTs are not new to Signum, but with the new portal it makes it easy to join and mint, buy, and sell. We hope you will enjoy the new portal under and mint soon your first green NFT.
