About Xentrium

History in short

The name Xen3c was derrived from the word "eccentric" in both its geometric and social terms. Needing the space for my creativity, Xentrium was founded in 2012 as a tech/hobby-site and was part of my exploring days. In the following years it turned into the homepage for my artworks, whilst still experimenting with different technologies & cryptocurrencies. Around the end of Q1 2020, I joined as a team member of Digitalnote (XDN) Now evolution allows me to combine the best of both worlds into a new digital era.

Frequently Asked Questions

How to redeem NFT locked content?

Visit Rarible marketplace, log in with your Metamask and go to "my collectibles". Click on the collectible and look for the details. You will find a button to unlock/reveal the content. * In some situations NFT's can contain wallets, those are represented by mnemonic phrases, You can import them in any wallet supporting this method. I recommend Mycrypto wallet on desktop or Metamask for online wallet. - Importing a mnemonic in Metamask can only be done when you are not logged in. It's best to backup any existing accounts in the current MetaMask instance before importing a mnemonic. When logged out, you can click Restore from seed phrase, right under the Login button. There, enter your seed phrase and set a password.
